Use the quicklinks below to jump to the desired section regarding transport in and around Ko Kut.
The closest airport for regular people is at Trat, which is served by Bangkok Airways, with multiple flights a day and fares starting at around 2,500 baht. The flight takes an hour. Soneva Kiri has a private airstrip on Ko Maisi Lek which lies just offshore from the resort. The airstrip is for guests only -- we have no idea what it costs!
Boats to Ko Kut leave the mainland from Laem Sok, about 30 kilometres from Trat, from Ko Mak and from Ko Chang. Boats from Trat should include free transport from Trat to the port and from the pier on Ku Kut to the general area of where you are staying. If you want to take a motorbike to the island you have to catch Ko Kood Princess (which is better anyway) as they have enough space for a bike. There is a 200 baht surcharge for a motorbike.

There is also a boat service that runs between Ko Kut and Ko Chang, stopping at Ko Maak on the way. The most popular service seems to be Bang Bao Speedboat.
Bang Bao Speedboat
Departs Ko Kut 09:00 and 12:00 taking 1.5 hours to reach Ko Chang (Ko Maak and Ko Wai are stopped at en route). In the reverse direction it departs at 09:30 and 12:00. Ko Maak costs 400 baht, Ko Wai 700 baht and Ko Chang is 900 baht.
Travel around the island is a little tedious and a little expensive. A taxi ride to your bungalow or resort should be included as part of any boat ticket Ko Kut.
Motorbike rentals are possible, but it's expensive at 300 baht to 400 baht a day (versus in Trat, where it's 150 to 200 baht per day). The main north-south road is sealed the entire way but it gets extremely hilly in places and with no shoulder and a light sprinkling of sand it can be treacherous at speed -- be careful and always wear a helmet.
If you bring a bike over from the mainland you'll need to pay a 200 baht ferry surcharge for the motorbike each way.
