Just 200 kilometers from Bangkok in the Gulf of Thailand, the T-shaped island of Ko Samet is famed for its white sandy beaches, exotic coral and crystal clear waters. Ko Samet has developed steadily over the past decade or so, but it hasn't been the victim of over zealous construction which has hit the likes of Ko Samui (or even Ko Chang). The island is typified for its splendid beaches and white silky sand, surrounded by tropical coral reefs and crystal clear sea. Tourists can also enjoy a plethora of delicious cuisine and fine nightlife.
It's a popular tourist destination for Thais and foreigners alike. As Ko Samet is so near Bangkok, the island is ideal for those in the capital wanting to chill-out with their families for a couple of days, without having to go through all that rigmarole of having to travel down south. It's only a 2.5 hour ride (in good traffic; expect 3- 4 hours in normal congestion) to Ban Phe, where one can take a 20-minutes ferry to the island.
Even though Ko Samet is only a few kilometers from the mainland, the island with its micro-climate (the driest archipelago in Thailand) gets much less rainfall than the rest of Eastern Thailand. The rainy season is May to September but even then it still has significantly less rain than the other islands in Thailand. Tourists should, however, be careful of occasional storms.
It is believed that once upon a time, Ko Samet was the home of pirates and that to this very day there are still lost treasures buried somewhere on the island. Thailand's legendary poet Sunthorn Phu was the first one to put this island on the map when he set his classical epic there, Phra Aphai Manee "The Story of Princes, Saga, Mermaids and Giants".
Even though Bangkokians had known about the beauty of Ko Samet for decades before, the Thai government put this island off limits and restricted overnight stay there until 1981. In that year, on 1st October, the Forestry Department of Thailand declared Ko Samet and its surroundings to be a National Park.
Most of Ko Samet, including all the good parts, is part of Khao Laem Ya-Mu Ko Samet National Park and thus has an entry fee. Thais pay 40 baht for adults, 20 baht for children (current as of October 2015); foreigners pay 200 baht for adults, 100 baht for children (current as of November 2018). The entry ticket, issued by uniformed officers at the National Park gate, is only valid for 5 days, so if you stay longer, you may need to renew your ticket. This two-tier pricing policy is applicable to all national parks. If you can explain, however, that you actually live or work in Thailand, then you may not have to pay the "tourist" price. One excuse for the difference is that "Thai citizens pay taxes". If you are a teacher and work in Thailand you may bring out some form of Thai ID - Driver's License, Teachers card or something like that and you will get the Thai fee. It seems like the fee is only during peak tourist season, as several tourists walk in and out without buying the pass.
If your ferry arrives at the main pier and you take a songtheaw to the beaches, there will be a stop at the main ticket checkpoint. The journey from the pier to the town centre is a fairly short stroll, taking less than ten minutes. If your ferry arrives at one of the beaches, an officer will collect the fee as you step out of the surf. Note that there is plenty of foot traffic in and out of the park to the 7-Eleven, ATM or other shops and restaurants and if you have no bags you can nonchalantly walk into the park without anyone checking your ticket. There is a road via the temple which avoids the checkpoint entirely. Note: some bungalows might give the impression that the entry fee is included in their booking, but it is not. You may also be asked to pay the park entry fee when boarding the ferry on the mainland, but if you mention you are staying outside the park boundaries they won't make you pay.
By car and taxi
As Ko Samet is an island, you first have to drive to Rayong. From Bangkok, you can take Sukhumvit Rd (Highway No. 3) passing Chonburi, Si Racha, Pattaya, Sattahip and onto Rayong. The total distance to Rayong is approximately 220 kilometers. If you drive onto Highway No. 36 at Bang Lamung (before Pattaya), you'll take a shortcut inland and save about 45 kilometers (but the scenery is not as impressive). There is also less traffic.
Taxi services are available from Bangkok. You need to specify Ban Phe since the pier at Ban Phe is at the lower outskirts of Rayong itself. The metered fare is approximately 1600 baht, but most drivers will want to go "off meter" for a fare ranging from 1500 baht (some drivers don't realize the meter is slightly higher) to 2000/2200/2500 baht. Expressway tolls of about 100 baht are additional. You can pick up a taxi that will go directly to the ferry piers at Ban Phe at the airports as you can for any other destination. You can also either grab a taxi from your hotel or guesthouse that is willing to make the drive on the spot, or pre-arrange a pickup from a taxi driver you like by asking for his cellphone number and calling to make a booking — the latter routine works best if you have a native Thai speaker to help you. Look for a later model taxi if you can. If fact do not get into older taxi's period. They are poorly maintained and will give you the run around. No one catches them and so he will try make up for it by taking you the wrong way, driving too quickly or slowly. Take new well maintained taxi's that look clean and you are less likely to be ripped off. The older drivers have been doing it for years and know all the tricks and all the scams and you will be in an argument before too long.
Pai Rayong Pow - means "Do you go to Rayong?".
If you are coming from Bangkok, there are a few main spots to take the bus to Rayong or Ban Phe, from which you can take a ferry to Ko Samet: Ekkamai, Mo Chit, Victory Monument, and Sai Tai Mai.
From Ekkamai: the bus from Bangkok's Eastern Bus Terminal (Ekkamai) to Ban Phe usually takes 3.5 to 4 hours, costs 200 baht (current as of May 2016), and terminates opposite the ferry piers. Tickets for the ferry from Ban Phe to Ko Samet can be bought at the same counter where the bus ticket was purchased. The bus may take a number of side roads or the main road, but could be slow due to road quality or congestion.
From Mo Chit: There is no direct service to Ban Phe from Bangkok's Mo Chit Bus Terminal — it only brings you to Rayong, from where you can take a Songthaew for about (20 Baht) to Ban Phe. Updated: there's mini-vans in Mo Chit.
From the Airport (direct route not possible, as of May 2016): There are direct first class bus services between Rayong and Bangkok's Suvarnabhumi Airport (as of May 2016, this bus between the airport and Rayong is no longer running; on the website, it still exists, but when inquiring at the airport, it doesn't exist. You need to go into the city to take a bus.). From the airport you can go to Pattaya. So, if you take a regular bus from Pattaya or Sattahip, you'll need to take a songthaew or charter a tuk-tuk to the ferry piers.
Updated, all mini-vans around Victory Monument have been moved to mini-van terminal opposite of Mo Chit bus terminal. From the Victory Monument: There are also mini-vans that leave from Victory Monument in Bangkok's Phahonyothin district. They charge 200 baht per person and bring you directly to the ferry piers. You can find the vans in the lane by Century Cinema near Exit 2 of the Victory Monument Skytrain Station. If you have a lot of luggage, it's customary to buy one extra seat. If just a backpackers' backpack or roll-on, you can usually fit it in the aisles. These buses only leave in the morning. So make sure you arrive here early.
Since all mini-vans in Victory Monument have been moved to Mo Chit. To take mini-van, you have to go to Mo Chit mini-van station instead. It's easy and cheap to go to Mo Chit if you know the way. The cheapest way to go from BTS Mo Chit is simply taking bus. From BTS Mo Chit, take exit 4, once go down stairs, turn around and walk for around 150m (Chatuchak park should be on your left on the opposite side of the road, parking lot should be on your right. You will pass mrt (subway) entrance and soon will arrive at a bus stop. Almost all buses that stop there will go to Mo Chit. Take 145 or 96 bus (6.5 bath or 11 baht for air conditioned). Mo Chit terminal is the terminal station. Once arrive, cross the road and you will arrive at Mo Chit mini-van terminal.
From the Mo Chit mini-van terminal to Ban Phe, there's van number 915 located in building C which costs 220 baht (with 20 baht discount on return trip if you keep receipt of the departed trip). The vans are comfortable and fast. Only one stop at gas station. Take around 3.5 - 4 hours. You can tell the drivers which pier you want to get off (recommend Nual Thip). For return trip, you can get off at Lat Krabang airport link station which is one station away from Suvarnabhumi surprised. You can book [www.thaiminibus.com online] (250 thb). Or you can buy directly at the counter in the van terminal.
From Sai Tai Mai: There is a minibus operating from Southern Bus Terminal (Sai Tai Mai) leaving ca. every 2hrs. It will take you directly to Ban Phe (220thb dec 2014). (make sure you get dropped at the main boat ticket office (24hrs open) at the departing pier, even if you get there late in the evening. Usually they take you to a travel agent that sells you overpriced speedboat tickets. Shared speedboat price should be around 300thb - max 500thb dec 14).
Going back: If you plan to get back directly to Suvarnabuhmi airport Bangkok, you can take a minibus from Ban Phe pier (200 thb May 2016). The tickets can be bought directly from an improvised booth a few meters from the pier main building. Just walk out of the pier building, turn left and find the minibus station on the left side. The bus takes you to Pattaya or the Bangkok Airport link train station, from where you'll need to take the train one station to the airport (15 thb feb 2015).
Bangkok Airways operates a flight daily from Phuket and Ko Samui to Pattaya's U-Tapao Airport. For more information, contact Bangkok Airways at number +66 2265 5678 or contact a travel agent. From the airport, it is about one hour by car or bus to reach the pier. This way of transportation is only recommended for travellers from Southern Thailand.
There are two main types of boats to Ko Samet, ferry boat or speed boat. The ferry boat should cost around 50 - 70 baht (one-way), depending on where you are taking it to, but is at least 30 - 40 minutes to get there. Ferry boats leave approx.every hour. Ferry boats are mostly used by domestic tourists. Speed boats are more expensive, between 200 - 400 baht (one-way), depending on your destination, but take only 10 - 15 minutes. Speed boats leave when they are full.
The boat ticket office is open 24 hours.
Ferries from Ban Phe or Nuan Thip (they are about 1/8 mile apart, with Ban Phe to the north opposite a 7-11) to Ko Samet take around 30 to 45 minutes. Only buy a one-way ticket (70 baht), as there's no discount on round-trip tickets (100 baht) and you won't have to worry about losing it or finding that your ticket isn't valid for the most convenient return ferry.
Note: The ticket sellers may state that you must buy your national park ticket from them also but this can be done at the gate as you enter the park. They may also state that you cannot buy the return from the island, and must buy it at the Ban Phe pier. This is not true. Only buy a one-way ticket at Ban Phe pier. If you arrive late in the evening at Ban Phe taxi or minivan drivers will tell you that the ticket office is closed and they will try to sell you an overpriced speedboat ticket. Just go to the boat ticket office (open 24 hrs), where the boats (speed and others) departs, and get tickets there (dec 2014, a shared speedboat from Ban Phe to Ao Wong Deuan after 8 pm: 300 THB). Most of the stuff from the island (hotel, restaurant workers and so on) gets chartered daily to and from the island by speedboat, so you will get a ride quite easily to and from there, until fairly late in the evening. The ticket office at Nadan pier quoted 200 baht for a one-way trip on the speed boat to be paid beforehand, but locals were seen to pay the speedboat crew only when they disembarked at Ban Phe, and they appeared to pay just 50 baht each. However the speed boat is really fast (10 minutes vs 40 for normal ferry) and waiting time is also shorter, so it depends whether you are willing to pay a premium for much faster service. If you arrive after the ticket office is closed you will not have to pay the entry fee.
Nuanthip pier (tel +6638651508/+6638651514) runs boats to various piers on Ko Samet. One-way tickets are half the price of a round-trip, you might need to insist of booking one. The boats tend to wait until full so you might be waiting a long time.
Alternatively, there are two speedboat companies that operate from Ban Phe. You will need to take a Speedboat if you arrive when the ferry is not operating. Prices can range from 500 baht for the boat to NaaDaan pier to a few thousand baht for the outer-lying bays and beaches. Service is available 24 hours a day, what you will end up paying is based on how many others also want to go to your destination. One advantage of taking a speedboat is that it will drop you off on the beach so you can avoid taking a taxi from the pier. The speedboats may make a number of stops along the beaches of Koh Samet but will still be a lot faster than the ferry which will take no less than 40 minutes as opposed to the 15-20 of the speedboat including stops.
For the return from the Ko Samet public pier, take either the Nuan Thip or Ban Phe piers for your destination — it doesn't matter which one you departed from as they are only a short walk apart, and you might get an earlier boat back if you are willing to be flexible and return to a different pier. Both are served by songthaews: Ban Phe has an informal "taxi stand" in front of the 7-11 across the street with passenger cars used as cabs but no need to go looking for them as they will find you. It costs 200 baht for a ride from Ban Phe to the Novotel, quite a distance down the coast, in early 2009.
There is a single main road and short, bumpy dirt roads branching off to the beaches.
The distance from the main town by the port to the beaches is not actually very great, much of it can be reached on foot by walking along the coastline. Many tourists are not aware of this & end up hiring vehicles they do not really need if all they intend to do is go to and from the main town.
A basic map of Ko Samet is available here. 
You can take a songthaew (usually a green pickup truck with two benches in the back), which costs up to 600 baht for a private trip, or between 20 and 100 baht per person for a full car, depending on which beach you are going to.
The alternative is renting a scooter for 100 Baht/hr 200-300 Baht/day. Gasoline is often included. You can try and negotiate better deals for 3 or 6 hours if that is all you want. It is best to hire one from close to the pier (Hat Sai Kaew) where there are many deals. Rental prices tend to increase as you move away from the main pier. The roads are of a good quality but there are some steep hills towards the South of the island. Leaving your passport or a deposit is not necessary or advisable.
Also available are ATV (4 wheeled motorbikes) for around 400 Baht/1hr or 1200 Baht/day or golf cars.
Remember to exercise diligence and caution when entering into a rental agreement.
Single Use Plastic Bag Ban: single use plastic bags are banned in the National Park, with a 1,000 baht fine applicable. The 7-Eleven outside the park entrance will not give you plastic bags (or any bags for that matter) when you buy anything, but will happily sell you a 50 pack of small plastic bags, which the Police/Rangers will then confiscate and demand you take everything out of the bags as you enter the park. So, best trick, if you need to shop from 7-Eleven and bring anything back into the park, bring a backpack. (They’ll also fine you for any single-use bags within the bag you are carrying, so bear that in mind...)
Most beaches are on the eastern side of the island. The beaches hide in small bays and stretch some 200 m. From the north, there are Hat Sai Kaeo, Hat Hin Khrong, Hat Khlong Phai, Ao Phutsa, Ao Thapthim, Ao Naun, Ao Cho, Ao Thian, Ao Wai, Ao Kio Na Yok and Ao Karang. The only beach on the western side is Ao Phrahis.
Note, the spelling of beach names can vary.
Beaches from north to south on the east coast:
Hat Sai Kaew (Diamond Beach) One of the most beautiful and most popular beaches on Ko Samet, Hat Sai Kaew is 1 km long and 25-30 m wide. Most of this space is taken up with deck chairs from the restaurants. The name speaks for itself, Hat Sai Kaew, which literally means Crystal Sand Beach, is a nice beach filled with activities. Visitors can enjoy sunbathing, swimming, jet skiing, windsurfing (700 baht/hr), catamaran sailing (1000 baht/hr) a banana boat or even partying at night. It can get a bit noisy due to all the motorised activity though.
Ao Hin Khok is separated from Hat Sai Kaew by a small rocky sea point where a mermaid statue is located. The beach is half the size of Hat Sai Kaew. There are some monk's accommodation along this stretch of sand that have signs asking people to be quiet. It makes for a peaceful spot just past the noise polluted Hat Sai Kaew Beach.
Ao Pai Located two beaches down from Hat Sai Kaew and just past Ao Pai. More or less of the same white, sandy stretches with a few nice restaurants at night and a big, concrete block of a bar where most party goers end up late at night.
Ao Put Sa is a small walk from Ao Pai Beach over a small headland. Suitable for those who are tired of crowded beaches and nightlife activities. Ao Put Sa has a small pontoon with some OK snorkelling around it. Best time to stick you head under and have a look is at low tide.
Ao Nuan is located a 10 minute walk through the bush from Ao Put Sa and is a perfect hideaway for holidaymakers in search of tranquility. All bungalows are handmade by the owner. Some have great character.
Ao Cho is a bit of a scruffy beach and if you have been following the "next beach" signs along the coast, you feel like you've seen better.
Ao Wong Deuan is the second largest beach on the island (the first being Hat Sai Kaew). Ao Wong Deuan has a ferry service with the mainland. It's best to talk to one the bungalows to book this than try and find it yourself.
Ao Thian (Candlelight Beach) Ao Thian’s topography is painted by rocky beach in which some nice spots for skin diving are available. This beach is very quiet and free from group tours.
Ao Wai is located within a short walking distance of Candlelight Beach but far from city center and no lights at night. Shaded by coconut trees, the beach is a quite, scenic and serene spot for sea lovers.
Ao Kiu Nok This bay is a secluded den for those planning to keep their distance from the busy, crowded beaches and vibrant nightlife. There is currently a huge resort being built with a swimming pool and the small bungalows are slowly being knocked down. The eatery isn't the best, but because it's the only one on the beach, it's pricey. From Ao Kiew Nok, visitors can walk to Ao Kiew Nai along the road, but getting a lift is better as it's hot, there's no breeze and not much to see.
Ao Karang is at the southern tip of Ko Samet. It's very quiet down here and could be the best place to experience the traditional lifestyle of the residents of Ko Samet.
Ao Wiang Wan is on the west of Na Dan Pier, a large bay where lots of sport activities such as fishing, etc., take place.
Ao Phrao ((See Oil Spill Update)) is one of the quietest beaches of Ko Samet. Located quite far away from the lively nightlife of Ko Samet. Ao Prow is an upmarket beach with no budget options. The blue sea, white sand and sunsets are all top notch. How to get there: Four operators: Nuanthip, Si Ban Phe, Phe Port, and Saphan Pla around Ban Phe offer shuttle boat services between their ports and the main port of the island. All operators charge a flat rate of 100 baht per person for a round trip or 50 baht for a single journey. Boats can leave anytime when more than 20 passengers are waiting. The service is available around the clock, seven days a week. It's best to just buy a one way ticket from the pier and head down to the end to wait.
For groups of at least 7 persons, Nuanthip Boat (+66 3865 1508) offers a shuttle boat service to other bays as well, such as Ao Wong Duean (120 baht each) and to the last bay Ao Pakarang (200 baht each). Si Ban Phe Boat (+66 3865 1902) also runs a scheduled boat service during weekends between Ban Phe and the main port of Samet. The hourly boat service from Ban Phe runs from 08:00 to 18:00. On the return trip from Samet, the boat leaves at 10:00, 14:00, 16:00, and 18:00. The company also offers a speed boat service at 1,000 baht a trip for 12 people to the main port, or higher rates for other routes. A parking service on the main land is available.
Ko Kruai, Ko Kham, and Ko Pla Tin (เกาะกรวย เกาะขาม และเกาะปลาตีน) These islands are some 600 m north of Ko Kudi. With coral reefs, tourists can enjoy fishing here. A rental boat service is available at the port in Ban Phe.
Ko Kudi or Ko Kut (เกาะกุฎี หรือเกาะกุด) The island is on the east of Ko Samet, 6 km from the mainland. Ko Kudi totals an area of 63 rai. A nice beach and coral reefs make it a nice place for a hideaway. Nearby islands are Ko Thai Khangkhao and Ko Tham Ruesi. Without accommodation, the national park office on the island offers a tent for rent at 200 baht per person/ night. Pitching a private tent requires paying a fee of 20 baht per person/night. For more information, call Tel. 0 3865 3034, or in Bangkok at Tel. 0 2561 2919 and 0 2561 2921.
Ko Thalu (เกาะทะลุ) Some 6 km east of Ko Kudi, the island is another scuba diving site among coral reefs. The island totals an area of 69 rai, most remains lush forest. While high cliffs occupy the west, white sandy beaches occupy the east and south of the island. Ko Thalu is a habitat for seagulls, flying fox, and turtles.
Tourists visiting Ko Kudi, Ko Kruai, Ko Kham, Ko PlaTin, and Ko Thalu should rent a boat from Ban Phe or Ko Samet. They should prepare food and water, as there are neither facilities nor food supplies available on such islands.
Ko Samet is a laid back island paradise where the emphasis is less on things to do and more on enjoying the islands beaches.
For those people who do want something to do, the island does have a few activities to enjoy if the beauty of the beaches is not quite enough to keep you occupied. From the simplest of activities such as walks along the beach, all the way through to taking your PADI Scuba Diving certificate, there is an array of ways to keep yourself active.
Ways to see the island - The island is very small in comparison to the more tourist populated Thai islands around, so exploring the island can easily be done on foot, bike riding or by hiring a motorbike/ATV and driving down the island to visit a few of the smaller more secluded beaches and taking in some of the more naturally forested areas further down to the south of the island.
Mountain Bike Rental - Mountain bikes can be rented from various locations in Ao Noi na and on the main road. Prices are normally 200b for one day.
Motorbike Hire - The island has more motor bike hire shops than any other shops so they are not hard to locate and prices are 300 baht per day for manual or automatic bikes.
Gold Shop - This motorbike hire shop is just up from the national park entrance and 7-11 (opposite Chilli Restaurant). This family take very good care of their motor bikes and ATVs. The owner 'Jep' is a very friendly guy and always willing to help. His son also rents their vehicles from next to the 7-11 by the park entrance and 'Bow' is also very helpful. If you rent for a few days he will often offer good discounts.
Boat Trips - There are several companies on the island offering a variety of different boat trips from around the island on a large slow boat to a 7 island speed boat day trip visiting many of the surrounding islands from Samet. These trips are all a good value but be sure to have a chat before you book and make sure you are getting the trip you want and that they are not talking you into another trip as they cannot do the one you are asking for. Also all trip are dependent upon weather conditions.
Samet Boat Trip - One of the original boat trip families on Samet still offer a daily round-the-island boat trip. If you're lucky it could be a private trip or one with just a few other chilled out people on board. Their fleet consists of 2 large slow boats and 4 speed boats so different trips are available daily.
Scuba Diving - With the calm surrounding waters and coral reefs Ko Samet has something to offer those of all levels of diving, but it is an especially good place to learn to scuba dive with classes nearly always on the smaller side and often one-on-one with an instructor. With depths ranging from 5 m down to 25 m, there is a variety of local sites to dive on and explore and there are also the outer islands that surround Ko Samet which offer stunning coral reefs, such as Ko Talu.
The only diving school on Koh Samet is UDI's Scuba Diving at Ao Phai. Prices: 2 Fun Dives: 3500 Baht, PADI Open Water: 13500 Baht, Advanced Open Water: 13500 Baht
Some of the best barbecues are found along Ao Phai and Haat Sai Kaew beaches but they are found on all beaches and most serve the same as the next. There's also local food, curries and Western like pizza, steaks and hamburgers. Almost every hotel and bungalow operation has its own restaurant but it's only the movies that differentiate them. Many also set up tables and chairs at night for dining on the beach. Crowds don't always mean they are good. The day trip companies make deals with restaurants and take their customers there.
If you are relaxing on the beach during the day there are plenty of hawkers selling fresh fruit, BBQ chicken wings, dried squid, papaya salad (can be extremely spicy) and even ice creams slightly more expensive than if you got up to get it.
At night check out the Roti stands that pop up everywhere. This crepe-like desert can be filled with banana and topped with chocolate syrup or sweetened condensed milk, or any number of other combinations from 40Bht.
In town (Na Dan), there are a few traditional Thai eateries that serve good quality Thai food priced for locals. Most have menus in English.
If you are after a traditional Thai breakfast there are a couple of ladies who set up their mobile eatery daily next to the Tourist Police checkpoint that services Haat Sai Kaew. They serve boiled chicken on rice (khao man gai tom), fried chicken and rice (khao man gai tort) or rice porridge (jok) for 20-30 baht. The food is fresh and they do a brisk trade serving locals as well as a few tourists.
Although Ko Samet is not a renowned party island, Hat Sai Kaew and Ao Phai do get their fair share of backpackers, and therefore have their fair share of parties. Everyday on Ao Phai, flyers are handed out from the different bars that advertise the drink specials for that night, and might even give you a free drink. Biggest nights are generally Thursday-Saturday, when more backpackers, expats, and locals from Bangkok come to the island.
The main bars along Hat Sai Keaw:
*Old-Amsterdam bar ,a Dutch bar on the mainstreet ,free wifi ,sports on demand tv ,very good cocktails ,cold beer and entertainment
Along Ao Hua Khok/Ao Phai are:
The local special cocktail can be reproduced as follows:
Place all ingredients in sand bucket and drink via straw. Repeat until the sandy beach rises up to meet you.
There's also the usual assortment of Thai beer - Chang, Tiger, San Miguel, Leo, and Carlsberg. Prices are significantly higher than on the mainland, but most bars have some form of happy hour. Alternatively, there's always the option of buying a 6-pack and sitting on the beach; for non-drinkers there are tropical fruit drinks.
Most of the accommodation centers around the beaches on the east coast; try to arrive on the island as early as possible to have the best selection to choose from. Tourist season on Ko Samet is generally from November till February and from June till August, at which time finding vacant accommodation can be a challenge. Also, beware of weekends and public holidays — the island then fills up like crazy!
The northern-most beaches of Hat Sai Keaw and Ao Hin Kok have many bugalow operations with typical Thai concrete bunker-style rooms. If your room doesn't have air-conditioning it can get a little hot during the day
At the very northern end are a few upscale resorts. At beaches further south you'll find the bungalows ranging from dismal shacks to four-star, air-conditioned mini suites.
Best idea: Arrive on island with little baggage. Hire a motorbike. Drive around until you a find a decent place at a decent price that you can afford. Avoid the green taxi type vans if you can. They rip you off. In low season no reason to book in advance.
Unless you've made the mistake of booking your room with the touts back at the dock you'll find a place by strolling down the beach. As this island becomes more and more popular it's getting harder to find rock-bottom prices. On some beaches you can expect to pay 600 baht for the basics. Most of the accommodation is first-come, first-served and the cheaper bungalows tend to go fastest. High-end establishments usually take reservations by phone, fax, and via the web, the cheaper ones do not.
Notice May 2013 A lot of the information in this section is dated by 2 years, the prices for many places in the budget range mentioned here have gone up and the standard prices for most now start from 700+ baht for fan rooms and 1500+ baht for rooms with Air Conditioning, especially places mentioned in Lonely Planet. Airbnb is starting to get popular on the island, so you may be able to find some cheaper options there.
Most accommodations on Ko Samet offer a variety of different types of rooms, most of which fall in the mid-range category. If you are willing to spend between 1000 and 2000 baht/night, you shouldn't have any trouble finding accommodation, no matter what beach you are on. A few such places are:
