Ko Kut (also Koh Kood) is an island in Trat Province in the Gulf of Thailand and the easternmost island before Cambodia. The island is a popular spot for package tourists and families. The island has virtually no night life, so if you are after partying this is definitely not the place to go.
Boonsiri High Speed Ferry or Koh Kood FantaseaCatamaran  . These two are the same, just different calling. (starting on 15 November 2013) 600 THB per person one way or 1200 baht per person incl. bus transfer from Bangkok. Pick up point in Bangkok is Khao Sarn Road and Shell Gas Station in Bang Na, at 7-8am. Sailing time between 70-90 Minutes. Departures at 2pm. daily from Laem Sok to Koh Mak(Ao Nid Pier) and Koh Kood(Bang Bao Beach), also during low season. free taxi from Trat to the pier in Laem Sok and Koh Kood.
However. do note that during 15 May-15 October which is considered monsoon season, Boonsiri's departure time is changed to 11.45 from Trat to Koh Kood, and 9.45 from Koh Kood back to Trat.
Ko Kut Express 350 THB per person one way. 1h15m. The boat ticket includes a free taxi from Trat to the pier in Laem Sok and on Koh Kood from the pier to your resort. Taxi's in Trat depart from the Market near the big clock/thermometer or your accommodation. Leaves the market in Trat at 11:30 sharp! Departs from Laem Sok daily at 12.30pm. Departs from Koh Kood daily at 10am, also during low season.
Koh Kood Princess 350 THB per person one way. 1h15m. The boat ticket includes a free taxi from Trat to the pier in Laem Sok and on Koh Kood from the pier to your resort. Taxi's in Trat depart from the Market near the big clock/thermometer or your accommodation. Leaves the market in Trat at 11:30 sharp! You can also buy ticket at Trat Bus Station. Departs from Laem Sok daily at noon. Departs from Koh Kood daily at 10.30am, also during low season.
Note that despite the same ticket price, same departure time, and same duration time, the difference between these two ferry companies is the boat. Koh Kut Express's Boat has only indoor seats with only one exit, though you can sometimes sit on the roof of the ferry with the cargo. While Koh Kood Princess's Boat is bigger, with both indoor and outdoor seats, and many exits. The other difference is the arrival pier in Koh Kood. Koh Kut Express arrives at 'Nam Luek Pier' which is on the west coast, where virtually all of the resorts are located. And Koh Kood Princess arrives at 'Ao Salad Pier' which is on the east coast, and will involve a 30+ minute ride from the pier to your resort.
Siriwhite Speedboat / CP Laem Sok Group 600 THB per person one way. 60-90 Minutes. Two speedboats depart daily from Laem Sok on the mainland near Trat. Stops are made on demand at most west coast piers on Ko Kut, finally terminating at Ko Kut's Bang Bao Bay. Boat departs from Laem Sok at 9am and depart from Ko Kut daily at 12pm. The speedboat tickets also include a free taxi from Trat to Laem Sok pier. The speedboats do not operate during low season due to the weather conditions.
Koh Kood Speed Boat / Ao Thai Marine Express This service is only available for private charters.
Note that the boat fee (350 baht slow boat, 600 baht speedboat) includes transport to/from Trat, but only when using taxis that are assigned by the boat companies. If you take the speedboat, you will usually be dropped at or very close to your destination.
Kai Bae Hut Express (speedboat) 900 THB per person one way. Daily from Kai Bae pier on Koh Chang at 9am.
Bang Bao Boat (speedboat) 900 THB per person one way. Daily from Bang Bao pier on Koh Chang (9am & 12pm)
The trip can take 1-2 hours depending on conditions and the number of stops at the islands between Koh Chang and Koh Kut, (Ko Mak, Koh Wai, etc.) and the number of stops around Koh Kood. The boat ticket includes a pick up or drop off at most hotels on Koh Chang.
Public taxis are available since 2013 on Koh Kood. Rates & times are not quite standardized yet, but that should not be long. Siam Beach Resort (located in Bang Bao Bay) also runs a taxi service. Another fun way to travel around is by motorbike. Expect to pay around 300-350 baht per day, resorts often charge 400-450 THB. Road conditions vary between dirt roads and paved roads but since 2009 there is a small concrete road covering the Western coastline from North to South. Maps are available though a bit confusing. Bicycles can also be hired (around 150 baht per day), but the heat and the hilly nature of the roads makes them of limited usefulness for all but die-hard cyclists. For those that are not in a hurry: small fishing boats can be hired to tour around the island.
Beaches The West coast has some breath-taking beaches, many of them bordered by undeveloped plots of land. Most resorts are along this coast. Bang Bao Bay is known for its calm water. The water is warm, and many beaches are essentially empty.
Klong Chao Waterfall The largest, with a huge pool that you can swim in. About 20-30 minutes' walk from the turn-off, sometimes you can hitch. Organized tours usually visit the waterfall in the afternoon.
Klong Yai Ki Waterfall In the North-West of Koh Kood. This waterfall is smaller, more quiet and also with a pool where you can swim. Follow the signs to Bann Makok.
River estuary Near the turn-off to the Klong Chao Waterfall is a mangrove-lined estuary. Many places (hotels, restaurants, guest houses) rent kayaks cheaply here. The top of the estuary is a rocky area, if you want to be alone in nature you can pass it by carrying the kayak then swim in a natural pool surrounded by forest. Very few people can be bothered to go here, so it is very clean. There is also a tributary flowing from a mangrove forest part-way up, on the western side. This is quite spooky and has more pollution as the top is a road and there are some houses at points the way, but you can still appreciate the natural environment, which is pretty spectacular at points and maybe see some rare bird life. You can also kayak out on to the ocean, which is often very still and without waves, and being shallow a long way out the water is warm.
Ao Salat is a fishing village in the North of the island. It can be reached by motorbike. This is also the departure and arrival terminal for the Koh Kood Princess ferry. It has a few very good sea food restaurants (including a home-stay & souvenir shop) where you can choose your own seafood straight from the fishing-nets.
Ao Yai A typical fishermen village (a real one!) at the extreme South-East of the island. The new concrete road brings you all the way to it. Good place to enjoy fresh seafood. Cheap snorkeling and fishing trips can be arranged here with local fishermen. Crowds of nice people will be happy to receive you there, even if they can only speak Cambodian or Vietnamese.
The 300 year old Macca Trees Certainly worth a visit, on the way to the Secret Waterfall  surrounded by impressive jungle.
'Khao Rearub This is an old kind of cave in a remarkable shape and it's a religious place for the Thais. It's also part of a trekking path.
Swimming in the crystal clear waters, sunbathing (there can be sand-flies depending on beaches and season), scuba-diving, snorkeling, kayaking, jungle trekking, trekking to the waterfall or just relax and read a book.
There are virtually no towns on Ko Kut so sightseeing is pretty limited. The fishing village of Ao Salat (northeast island) is home to around 300 people, making it the largest settlement on the island. The village is built on stilts in the water, and is quite interesting and well worth the the rather long road trip to get there. Expect to pay around 500 baht for the trip as cars are quite scarce. Or rent a scooter to get around.
Scuba diving is a great way to discover the underwater world around Ko Kut. Diving off Ko Kut is easy, fun, and you can see turtles, stingrays, barracudas, lots of small fish and sometimes sea horses.
Nearly any time of the year except from July till end of September is good diving weather in Ko Kut and visibility can exceed 30 m. Average visibility is around 15-20 m. From July till September visibility is reduced to 5 m and the seas are choppy.
It is possible and perfectly comfortable to swim and dive without a wet-suit year round. However, as with most diving, a wet-suit is recommended to help reduce risk of cuts or injury. Avoid contact with coral reefs.
Various dive locations around Ko Kut are:

Many of the resorts, but not all, have good restaurants. Outsiders are always welcomed . Now also a few restaurants are popping up including the rustic locally-run Chiang Mai Restaurant (by far the best food in koh kut. Big portions, amazing tastes and really cheap. Make sure you visit and try the sweet red curry)  and a Thai/Italian-run Italian pizza and pasta house . But for the ultimate in ambience View Point Cafe is tops. Located on top of the waters of Klong Chao with great views across to the ocean.
Prices on Koh Kood are slightly above mainland. The cheapest feed is roughly 60 baht for a bowl of noodles. Expect to pay 80-200 baht for a main course at non high-end places (usually 100-150 baht).
If you want to cook for yourself then a small selection of fruit/vegetables is available at a stand/shop operating some distance across the bridge from Ban Klong Chao, before the Sunset Bar. Basic staples and ice cream are available at a number of shops around the Khlong Chao.
Sunset Bar across the bridge (1 km) down the road from Klong Chao, just before you reach Away Resort. Admire the sunset there around 18:00 or just go later to enjoy the drinks in a cool atmosphere. Parties going on every Saturday until midnight..(local police regulations) and on special occasions.
View Point Cafe new location near Away Resort on the main road near the bridge. The new View Point Cafe is build directly above the water with magnificent views, sunsets, and ambience. Real fresh-ground Vietnamese-style coffee, fruit shakes, and interesting non-alcoholic cocktails. The Australian/Thai proprietors of the View Point Cafe are a great source of local and SE Asia information. Same owners, same great coffee, drinks, and snacks menu.
For high season (November - February) it is recommended to book ahead, especially in weekends. Although there are many different places to stay, most of them can easily be fully booked during Thai holidays that Western tourists are usually unaware of. Also, apart from the Klong Chao area, Koh Kood is not an island where you can easily stroll from resort to resort.
About 40% of the resorts remain open during the rainy season (May-September). Expect services to be limited during that period. Some restaurants, bars & shops close, diving is not always possible etc...
Accommodation is widely spread out over the island with Klong Chao in the middle where most activity is. Low budget/backpacker accommodation can be found there. Most beach resorts are connected to the main concrete road by dirt tracks.

Compared to neighbouring Ko Chang, infrastructure is much less developed. Electricity regularly cuts out, and many resorts do not have backup generators. Some resorts offer Internet access (such as Siam Beach Resort, Hindard, and Koh Kood Resort) while others do not. Internet appears to be offered via 3.5G UMTS (i.e., mobile, quite slow) and is prone to dropping out. Mobile phones with "happy dtac" sims work on 2G (SLOW) other networks unconfirmed.
Local tourist information is hard to come by, but Internet searches will reveal maps of the island.
NO ATMs OR BANKS! Take cash. Only higher-end resorts take credit cards. If you run out of money, second-hand sources report that credit card cash advances are possible at the larger resorts for a 5% fee.
