Things to do in Phuket & the Thai Islands

Thailand's islands come in two seas. On the Andaman side, Phuket is the big hub, and boats run from it to the cliffs and lagoons of the Phi Phi islands; further south, Koh Lanta is the base for longtail trips through the quieter Trang islands, with Koh Kradan's beach and the Emerald Cave on Koh Mook. Inland, Khao Sok National Park hides Cheow Lan Lake, where karst towers rise straight out of green water.

On the Gulf of Thailand side, little Koh Tao is known for snorkelling and diving, and its neighbour Koh Nang Yuan is three islets joined by sandbars. This page gathers our island and lake trips from all of these bases.
