Koh Phi Phi
Thailand · Andaman Sea
Iconic limestone karst islands rising from turquoise water between Phuket and Krabi. Reef walls drop 30 m alongside granite boulders, leopard sharks rest on sandy plateaus year-round, and seasonal whale sharks pass through the channel during March and April. The shallows of Bida Nok and Bida Nai hold some of the healthiest hard coral cover in the Thai Andaman.
