The island is geared towards diving tourists more than backpackers on a budget and offers both basic through luxury accommodation. There are hardly any currents and a wide selection of dive sites and dive shops, schools and resorts.
Ko Tao is a small island of approximately 21 km² and receives over a 100,000 visitors per year. To minimize your impact on the eco-system, notice that there are no garbage disposal facilities, so everything that can't be burned has to be taken away. Try to avoid plastic bags that are given out for every purchase you make. There is also no department to clean the roads or other public areas, so don't dump your waste on the open landscape. Water is scarce and electricity expensive, so don't waste them.
Historically Ko Tao was once a detention place for political prisoners similar to Ko Tarutao in Satun Province
Peak seasons in Ko Tao are from December to March and July to August. July/August is actually high season due to Northern Hemisphere summer and rain dominating most of the rest of the country. The Gulf of Thailand is on a separate weather system and is usually sunny, however regional instability - such as Typhoons in the South China Sea can provide daily bouts of rain. Monsoon is in Nov-Jan and can be constant rain for days at a time. It is a quite popular destination among Thais also, so it can be nearly fully booked on Thai holidays.
Note on safety: there is an ongoing Murder trial into two British tourists killed in 2014. This has uncovered the significant issues of drugs, police corruption, and mafia-style families which run the island. In addition several tourists have drowned while swimming in the last few years.
This option is one of the fastest to get to Koh Tao and generally much less expensive than via Samui Airport.
Nok Air  operate two daily flights between Don Mueang Airport (DMK), Bangkok and Chumphon Airport, Pathio with van transfer for the 55 minute ride to the ferry terminal. Nok Air sell an integrated Fly 'an' Ferry combi ticket from Bangkok to Ko Tao via Chumphon Airport directly on their website, this combines flight, transfer and high speed ferry in a single ticket.
Fame Tours and Services have a counter at arrivals hall offering transfer and hotel services. This is the best option for transfers as the airport doesn't have a meter taxi service.
Lomprayah has a counter offering transfers and tickets for high speed catamarans.
The TAT Tourism Authority of Thailand, Chumphon has a tourism information counter offering information on the region adjacent to the airline counters.
Note in 2015 Lomprayah will move the main ferry terminal and pier to a new purpose built facility at Cape Pathiu about 2 km from the Chumphon Airport in Pathiu. This will reduce travel time from the airport to pier by 50 minutes and cut 90 minutes from the bus journey from Bangkok to the ferry pier. The new pier will likely be complete mid 2015.
Samui Airport IATA Code (USM)
Samui is fairly well connected to major cities in the region such as Bangkok, Penang and Singapore. Thai Airways, Bangkok Airways and Silkair operate from the private airport in Ko Samui and both charge artificially high rates. Bangkok Airways operates more daily flights to and from Ko Samui than Thai Airways. There is a 300 baht departure tax for all flights.
Several airlines, including Thai Air Asia, Nok Air and Thai Airways operate from the Surat Thani Airport.
The closest departure point for the island ferry service is Chumphon. Numerous agents sell tickets for a variety of boats and speeds travelling. The fastest Lomprayah High Speed Catamaran takes about 90 minutes, the slowest night boat almost 5 hours. Lomprayah have a pickup service from your hotel to the pier for 100 baht. The ticket itself is 600 baht wherever you book it.
These ferries depart Chumphon at 07:00, 13:30, 23:00 and midnight. The ferries at 07:00 and 13:30 are the normal passenger ferries offered by
- Lomprayah  - High Speed Catamaran service about 90 minutes
Both Lomprayah and Songserm sell packages from Bangkok by bus or Nok Air  offer a fly / sea combi ticket.
The late night ferries are normally vehicle or cargo ferries, making for a slower (5-6 hour trip, arriving at 05:00) and offer a comfortable bunk bed in a dormitory included in the 300 baht ticket. If you are arriving via bus or train, be sure to arrive well before the ferry times, as the ferry terminal is around 1 hour travel time from the train station, and a missed connection either results in a late night trip on the vehicle/cargo ferry or an overnight stay and a 05:30 start to catch the bus to the ferry terminal for the first ferry the next day.
A good option for travelling from Bangkok is to book Sleeper Train #85; leaving Bangkok around 19:30 and arriving in Chumphon at 04:00 and then have a ticket booked for the 07:00 ferry. Most ferry operators can pick you up from the station where you can while away the 3 hour connection gap. You can also buy your ferry ticket at the station when you get off the train at 04:00.
If you're coming from the south, you can take a ferry from Don Sak pier, 60km from Surat Thani on the mainland with a travel time of around 3 hours for the morning ferry, or from Ko Samui, 1.5 hours, or Ko Pha Ngan 1 hour. If you're taking a boat from Surat Thani, one possibility might be an overnight ferry. These depart around 23:00 and arrive in the morning, about 06:00 (subject to changes). It's advisable to arrive early to grab a mattress as most of the boats are former cargo boats and so the passenger facilities are basic.
You can also day trip on diving charters from Ko Samui. Many have high speed boats that can make the trip to Ko Tao in about 1 hour.
Lomprayah High Speed Catamaran  or Seatran  are the fastest and most comfortable way to get to Ko Tao. They run twice a day from Ko Samui, Ko Pha Ngan, Surat Thani, and Chumphon. They also have online booking - useful for checking availability at peak times and all their boats have air conditioning and movies for passengers.
Booking from Ko Samui can cost 500-1000 baht on the streets. You can get a ticket for the slower boat (2.5 hours) as low as 250 baht if you buy it in the ticket office next to the pier (next to 7 eleven). You can get a ticket on the spot, no need to book in advance.
Poster warning of motorbike rental risks in Ko Tao
There is no car rental in Ko Tao. Your only options are motorbike/ATV rental, or 4WD/boat taxi hire.
The roads in Ko Tao will set you for some of the most dangerous driving to be found in the country. A labyrinthe maze of concrete and eroded dirt roads that often go beyond a whooping 45 degree inclination, means that if you want to be really sensible, 4WD taxis (apart from boats) are the only vehicles that can safely reach these destinations. An average trip will set you back an exorbitant 500 baht one way (per car).
When it comes to self driving, 70% of the island is meant to be accessible only by the most skilled of off-road motorbike riders, but unfortunately everybody seems to be giving it a go in Ko Tao. The result is that there are accidents on a daily basis, sometimes with a very bad ending. The roads are extremely steep, deformed by intense rainfall with deep cuts that has carved the road in slices, and your flimpsy scooter (or even worse your ATV), especially with 2 people, has little chance of not skidding on the crusted fine gravel all the way to the bottom of the road grazing everything along the way. It is a common sight to see people bandaged up in Ko Tao. This is not the place for anyone to learn how to drive, and case of trouble, serious medical attention is several hours away. Furthermore, there is a bizarre island-wide agreement amongst renters in Ko Tao that dictates that damaged motorbike parts are to be replaced, not repaired, something quite unique in Thailand. The slightest implication in a fall or wipeout can set you back several thousand baht and you may see very fast the ugly face of your friendly renter.
There is one main road running north to south on the island with many smaller roads diverting off it. Some roads lead over the spine of small mountains that run along the middle of the island and are all dirt, can close out after rain, and can be challenging even to a skilled driver. If you are looking for an adventure, the dirt roads are a good place to find it, also be aware as distances can be quite deceiving due to the quality and elevation changes of the trail.
Be aware when filling up any vehicle with gas (petrol or gasoline to non Americans). Attendents will often distract you (particularly in pairs) and try to draw your attention away from either the fact that the pump has already been used and not refreshed, thus charging you for both transactions; or they will quickly refresh the pump used for your vehicle and point to an adjacent pumps higher reading. This is particularly the case at the gas station up the hill from the pier in Mae Haad, whilst you may need fuel immediately the next station is less than 1km away in Sairee. Due to the intimidating nature of the three or more men working at the Mae Haad station, as anywhere in the region it would be advisable to buy gas from the minutely-inflated roadside stalls dotted across the island, gas is pre-measured in whiskey bottles.
There are usually plenty of taxi cars available on both Sairee village and Mae Haad, however they tend to be expensive given the distances travelled. The best way to travel is by renting a small scooter or motorcycle, and this gives you the freedom to explore all of the treasures of the island without paying the large taxi costs.
Taxi drivers have begun carrying around a small piece of laminated paper with the 'official' minimum prices for journeys, whilst the official prices state no journey can be less than 300 baht they will dip to 200 baht (100 per person). Whilst the majority of people will stay within 1 kilometre of the pier these prices are extortionate. It is cheaper to rent a scooter for 24 hours and transport your luggage yourself.
You can rent bicycles and motorcycles at a few places on Sairee Beach, Mae Haad, and Chalok. Be careful if you rent a motorbike as the dirt roads can get dangerous. ATV's (all terrain vehicles) are dangerous (ask any medical clinic) and expensive (500+ baht/day) and should be avoided in favour of Honda Dreams (150-200 baht/day) or Sonic's (200-250 baht/day).
It is normal practice for motorcycle rental places to ask for a passport as deposit, this is due to the fear of drunken tourists crashing their bike and not returning it. You should be wary of handing over your passport unless you are positive of the legitimacy of the operation.
Be aware that an increasing number of rental shops are charging large amounts of money for non-existent scratches on bikes when returning them, notably the shop next to 7-11 in Sairee Village (Save Way travel) and Owen Bikes opposite the petrol station in Sairee Beach. Make sure you note down and photograph all scratches and dents before you rent a bike from anyone. A good option is to hire a bike from your bungalow/resort.

Longtail boats offer rides to and from certain beaches on the island. They are a more comfortable way of getting to isolated beaches than attempting to ride over the mountains, however they are noisy. Round island longtail can be as much as 2,000 baht, whereas some short trips will only be 100-200 baht.
Take a bike around the island. Shark Bay is a good place to go snorkelling for the day (don't worry too much about sharks, they are only small black-tip reef sharks). Ko Nang Yuan, Freedom beach, Laem Thian, Mango Bay, Hin Wong Bay and Tanote Bay are good day excursions, and are accessible by road or boat. Some roads, such as to Mango Bay, are more suited to dirt bikes or cars rather than scooters.
Many rental scooters come equipped with off-road tyres, which help tremendously with navigating the crevasse riddled dirt trails. Mango Bay and Laem Thian are accessible by scooter but are challenging rides and suited to more experienced riders.
However, to see the best places, go by foot as some are inaccessible to motorists. There are a number of good viewpoints around the island such as John Suwan Mountain Viewpoint in the south of the island, Two View in the centre, and Fraggle Rock in the north.
All beaches in Thailand are public. Some property owners may try to give the incorrect impression that "their" beach is private.
Freedive training and education worldwide is generally done through AIDA , SSI , Apnea Academy  and Apnea Total  freediving courses.

Scuba diving is still the biggest attraction on Ko Tao. Diving in Ko Tao is easy, fun, and you can see turtles, stingrays, barracudas, lots of small fish, reef sharks and there is a very small chance of seeing a whale shark.
At Chumphon Pinnacle you are likely to see juvenile bull sharks which have, until recently, been misidentified as grey reef sharks. Caution: the bulls are curious and very aggressive though for many years thousands of people have dived this site without a single shark-related incident.
Nearly any time of the year except November is good diving weather in Ko Tao and visibility can exceed 40 m. Average visibility is around 15-20 m, which in November is reduced to 5 m and the seas are choppy.
It is possible and perfectly comfortable to swim and dive without a wetsuit year round. However, as with most diving a wetsuit is recommended to help reduce risk of cuts or injury. Avoid contact with coral reefs.
There are a huge number of dive operators on the island, many offer budget or even free accommodation, but this is not really true as you will usually get a discount if you stay elsewhere. In 2012 the price for PADI open water certification including the new PADI training manual, professional instruction, rental equipment, boat dives and certification was around 9,800 baht, and for SSI open water certification including, professional instruction, rental equipment, boat dives and certification around 9,000 baht; insurance and basic accommodation may also be included.
Things to consider before taking your courses:
1. Class size - Smaller the class size means you will get more personal instruction. Scuba diving is not like swimming in a pool with goggles. A couple of deep dive points and a wreck and cave. Ask the shop how many divers are in the class. Big classes then the weakest diver will get the most attention.
2. Instructor Level - Not all instructors are the same, after doing multiple fun dives technique can clearly be an issue here with the dive masters and dive instructors. As a rule of thumb where the instructors have had their experience at usually rates them as how good of a diver they are. Ask instructors how many dives they have had, where they recieved their certifications, and years of experience.
3. Price - cheaper is not always better, try to check either on the internet or once on koh tao, the dive shop that is corresponding the best to you. Make sure teaching materials are up to date, equipment is in good condition, and people are talking the language you need properly, your first steps in diving are very important and it is a special time for you, so make sure you put all the chances on your side, and choose a dive center that fits you!!
Dive Instructor trainees looking for jobs here are tough as there is always applicants in waiting.
A common method for teaching new divers is to train in a pool first by being taught about 20 basic skills before being taken out into the open water. Others will instead take you to a secluded beach so you will see fish and coral from the start and you might be able to squeeze in a short extra dive in this way, depending on your group and instructor. Some shops have a private pier, some shops depart with a longtail from the beach, and some use the public pier, where you will have to climb some other boats. Ask if this matters to you. Most important: find out the maximum number of dive students in a group, and make sure you get an instructor who speaks your language if you are not absolutely sure about your English. These are the little things that will make the difference between an OK course and a great one.
Watch out for dive instructors who may offer you the Nitrox-course without telling you they charge extra for it.

A huge selection of Thai food is available, including lots of seafood. Barbecued fish is one of the local favourites. As a large portion of the population are expats, you will find plenty of other cuisine as well. Prices range from 60 baht for stuff-on-rice through to 250 baht for a nice hunk of fresh barbecued fish at a decent restaurant. 30 baht would get you a fresh banana pancake, and 60 baht a bowl of porridge with honey at a budget resort restaurant. 200-300 baht would get you a bowl of freshly made Italian pasta, and 160-200 baht for pizza.

When you get a break from diving, there are a few bars on the island. The bars on the island rotate nights, so the best bet is to ask someone working at dive shop which bar will be crowded that night or check the posters. Many start off the evening at the bars located at the north end of Sairee, and after they close at 01:00, go onto whichever club is open for the rest of the evening at the south end of Sairee.

You can usually find accommodation at the pier when you arrive. However, during peak times it is worth booking ahead unless you want to sleep on the beach or spend the night in one of the more expensive lodgings. If you are planning on taking a scuba diving course whilst on the island, most dive schools have an attached resort and will either discount the accommodation or throw it in for free when you book a course. During busy periods, most resorts with dive outfits will not want you to stay unless you are diving at least every second day with them. If you don't want to stay with your dive operator and use their free accommodation, you may want to ask for a discount.
The majority of the accomodations on Ko Tao are centred around two main areas: Sairee Beach and Chalok Bay.
This is the largest beach on Ko Tao, located on the west side of the island from the ferry terminal on the southwest corner of the island and running almost the length of the island. All along this beach you will find dive schools, resorts, restaurants, and bars. The southern and central sections of the beach are well-known for their night life, and the northern end has a large number of shops and restaurants which tends to be a bit quieter at night, but with the bars only a short walk down the "Yellow Brick Road".

More populated than other east coast beaches, but this doesn't mean it's busy. There is no town or village here and only 4 resorts, each with an attached restaurant and one really tiny shop which is up the hill behind the resorts. There are no ATM machines. There are no really cheap places to eat as there are in Mae Haad.
The sand on the beach is coarse and there is an unbelievable amount of broken glass in it. Likely because of people drinking while sitting on the rocks. Careful where you step and do your bit to pick up some of the glass. The shore is rocky and there is plenty of coral right off the beach. You can rent snorkelling equipment for 100 baht per day. There is a large rock just out to sea for those interested in cliff diving.
There are regular trucks that go back and forth 3-4 times per day at 100 baht per person. Ask at your resort for taxi times. Alternatively you can charter your own truck for 400 baht minimum or 100 baht per person.

This is the main spot of Koh Tao where any ferry will arrive at a pier. There are a lot of shops: Restaurants, 7-Eleven, Diving Shops, Travel Agents, Post Office, Banks, Motorbike Rentals and anything else you will need.
The number one way to stay safe on Ko Tao is to not drink and drive. Motorbike accidents are very common, especially when driven under the influence, on the wrong side of the road, in the dark. All Terrain Vehicles (ATV) are becoming numerous on the island. They are considered a menace by many as they are expensive, slow, noisy, and more people injure themselves on them under the mistaken belief that they are safer. Walk or hire a smaller motorbike instead. Be aware that motorbike hire is cheap, but can become very expensive if you so much scratch the vehicle. Hire an older bike rather than a brand new one.
Be always careful when renting bikes and be honest to the motorcycle owner.
Please be as honest and specify any damage to the rental bike at the return to the lender. A concealment of damage, and strain it even the smallest scratch, cause the next customer will be held liable. Not without reason is in most cases not to blame the rental shop that there is a problem at the return of the motorcycle, but unfortunately the previous guest who has made no indication of the damage. Therefore, you are always honest with each other, please: as a tenant for Bike Rental and as a motorcycle owner to tenant. Be fair to each other, it also works with a frictionless renting motorcycles. There are a high percentage of travelers who have never had any problems with the hiring and the return that shows us that a motorcycle rental is working very well. Please be fair to each other!
Owen Bike which has several locations on Ko Tao such as one on Sairee Beach. You must give them a passport as a deposit, and even though you may take photos and return the bike in perfect condition, the lady will find small scratches and demand an exorbitant amount.
Also avoid the overweight lady with a large mole on her nose who has a shop joining the petrol station in Sairee Beach (across from the 7-11). She runs the same scam, as sadly many other shops do.
Koryan Shop on a road from the pier to the main road. They will rob thousands of baht for smallest scratch. The police does not help in such situations. They only suggest, that the only way to avoid the payment is to "lose" your passport and report it in Bangkok on a way home. There you will pay only 1000baht for a paper to get into plane.
Siriwan Kahn. It's located opposite the Capuccino, next to Ying Yang restaurant in the south of the island. Same as everywhere else, the owner insists on scratches you didn't make, but unlike other places, this guy also gets violent and might punch you in the face.
CJ Guesthouse & Supermarket 13/1 Moo 1, Had Sairee Beach, situated on the same street as New Way Divers. They will not issue receipts if you do not ask, and later demand that you have not paid the cumulative rental fee when you return the bike. Without a receipt, it will be frustrating and difficult to argue your case. Do not trust the husband-and-wife team.
Sometimes bike rentals in the island claim a high amount for a unexisting scratch so be really carefull. They will all look like good guys but they will try to claim your money.
Bing in the middle of Sairee beach seems to be trustworthy. If you do get in such trouble the Ko Tao the police are helpful. A friendly police officer named Chet who speaks very good English who might encourage you to file a report, saying that this happens several times a day on Ko Tao. If you don't file a report, the police can help you negotiate a better fine. There is only 6 police officers in an island who receives a lot of tourists per day, If you do file a report, contact your embassy and eventually the company will have to release your passport because it doesn't belong to you but to your government.
INSIST on a receipt when you have paid the rental fee, or for every subsequent payment per rental day. Do not trust the shops to write accurate information in their own books. If you do not want to provide your passport as a deposit, some shops will ask for a amount as a one-off deposit instead. Again, take as many detailed photos as you can on the condition of the bikes.
According to the Bangkok Hospital Samui in Koh Samui there are a lot of dengue cases coming in from Koh Tao. Always use mosquito repellent, even during daytime and under clothes, and use long sleeves and pants whenever possible. Favor air conditioned rooms and always use a mosquito net tucked in under the bed. Read up on how to avoid mosquito bites.
Should you be unfortunate enough to need minor medical attention there are numerous clinics on the island. These, however, are only clinics, there are no formal medical facilities on the island. The closest hospitals are on Ko Samui or in Chumphon. Any medical condition not treatable locally will require a minimum of two hours ferry travel to reach a hospital. If the weather is bad, the physical rigours of such a trip can complicate medical treatment significantly. The local clinics can take blood samples and send them to Koh Samui for analysis. They will charge you for this even if you have a traveller's insurance, but you can insist on getting a receipt and get a refund from your insurance company. You can also insist on going to the hospital in Koh Samui in which case you should get your money back and the hospital will likely deal directly with your insurance company.
The entire island of Ko Tao has no sewage processing. Water contamination far exceeds Western standards at nearly all times. This includes both ocean waters and tap waters. Sewer water drains across the beach and even the roads in several areas and are easily encountered by unwitting tourists.
Small scratches or mosquito bites can become seriously infected if swimming, and ear/eye infections are extremely common among divers, more than many equivalent resort locations. Susceptible individuals and especially parents of young children should be aware of these dangers and exercise great caution.
Tap water supplied by shallow well pumps should be held suspect even during showering. Low-lying areas in Sairee and especially in Ban Chalok are the most polluted. The eastern areas far from the population centres are the cleanest.
Be also aware of the safety of your hotel room. There are many reports of stolen money especially in the resorts on Sairee Beach. Normally the thieves, sometimes even hotel staff, sneak into the room while you are out diving and take your cash from your wallet or from your bags.
