There are two ways to get to Ko Kut from Ko Chang's Bang Bao harbour. Either the slower Inter Island Hopper, which takes 3-4 hours, or by speedboat. The price by speedboat is 900 baht (as of Jan/Feb 2008) one way, which includes a pick up or drop off at your hotel on Ko Chang. The trip takes about 1-2 hours, depending on conditions and how many stops the boat has to make at the islands between Ko Chang and Ko Kut (Ko Mak, Ko Wai, etc.) and how many resorts on Ko Kut the boat stops at before it gets to yours.
Getting around can be a bittle of a hassle since taxis are not available. The best way to get around is by motorbike (expect to pay around 300 Bath per day) which can be rented at almost all resorts. Road conditions vary between dirt roads and pathed roads. Maps are available though a bit confusing.
Bang Bao Boat has a speedboat and one or two competitors.
Not much, really. Except swimming in the crystal clear waters, sunbathing, scuba-diving, snorkeling or reading a book. There are virtually no roads or cities on Ko Kut so sightseeing is pretty limited. The fishing village of Ao Salat (on the North East of the 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 gruelling road trip to get there. Expect to pay around 1.000 baht for the trip as cars are quite scarce. Or rent a scooter to get around.
There is a souvenir shop in Ao Salat. Other than that, you'll be hard pressed to find anything in particular to buy outside your resort.
Cross your fingers and hope your resort has a good restaurant. You can't go anywhere else to eat. But most of them do.
Singha, Chang, the usual.
Compared to neibourhing Ko Chang infrastructure is generally thin. Some resorts offer internet access (such as Siam Beach Resort) while others do not.
