Diving & snorkelling
The Similans, Koh Haa, Koh Bida and Koh Tao. Best from November to April on the Andaman, and year-round in the Gulf.
The Andaman's best sites are liveaboard territory: the Similans and Koh Bon are three to five hours offshore. Day trips from Phuket and Krabi reach Koh Haa and the King Cruiser, which are good but not the same.
If you are not certified, a discover-scuba day is a sensible first step; if you are, tell us your logbook level and we will match the boat rather than the price.
