Your Travel Guide to Thailand
All information & tips to prepare your trip in Thailand
Ferries to Koh Samui, Koh Tao and Koh Phangan (which also carry cars and scooters) leave from Donsak, 70 km from Surat Thani; speedboats to the same islands also leave from Chumphon. For Koh Chang, Koh Wai, Koh Mak and Koh Kood, boats leave from Laem Ngop, south of Trat. For Railay, which is not an island but a peninsula only accessible by sea, boats leave from Ao Nang or Chaofa Pier in Krabi. For Koh Phi Phi and Koh Lanta, boats leave from Krabi, Railay and Phuket, and for Koh Samet from Ban Phe near Rayong... If you have booked a hotel, it sometimes also arranges the boat transfer to the island.
The easiest way to buy boat tickets is from travel agencies or at the boat companies' desks at the pier, or online on this website. Check the companies' websites (see below) to get an idea of prices before you go; some also offer online booking. Be careful during ferry crossings if you are traveling with a combined bus + ferry ticket: don't leave anything valuable on the bus, even in your luggage, as bags are sometimes searched and items stolen during the crossing.
