How ferries work on the Eastern Gulf
Koh Larn from Pattaya
Koh Larn is the closest island to Pattaya. Public ferries and speedboats leave from Bali Hai Pier at the south end of Walking Street and land at Na Ban village or Tawaen Beach. It is an easy day trip, but check the time of the last boat back.
Koh Samet from Ban Phe
Koh Samet lies off the Rayong coast, a few hours from Bangkok. Ferries and speedboats leave from the piers at Ban Phe for Na Dan pier or the beach resorts. The island is a national park, and an entry fee is charged on arrival.
Koh Chang, Koh Mak and Koh Kood
Further east, near the Cambodian border, car ferries cross from the piers at Laem Ngop on the Trat coast to Koh Chang. High-speed boats leave Laem Sok for Koh Kood and Koh Mak. In the dry season, speedboats from Bang Bao on Koh Chang link the three islands.
