The closest bay to Shark Island

Sai Daeng Beach

Sai Daeng Beach, Koh Tao

Sai Daeng Beach is a small sized sandy beach with crystal clear water and a great view of Shark Island, It is a good place to see the ‘Golden Shark Island’ phenomenon which occasionally happens just before sunset depending on weather conditions and cloud cover.

Sai Daeng Beach is also the closest bay to Shark Island, taking just 10 minutes to get there by kayak in calm weather. Underwater here is good to explore with more chance to find blacktip reef sharks or sea turtles that live nearby around Thian Og Bay, Taa Som Bay and Sai Daeng Beach.

Good snorkelling spots are on the west and east end of the bay where there are various kinds of coral combined with rocks. You may swim east around Cape Gong Sai Daeng to Hin Ngam Bay (which means beautiful rocks in Thai). As its name suggests, the bay is laid about with beautiful big round shaped rocks underwater and with the many corals make it a very good snorkelling spot, though be careful of the current around the cape.

The roads to this beach have been blocked, so visitors must pass through either one of the two resorts. Vsitors are welcome and there is no charge.

A remote bay but not difficult to access. There are only two resorts located on this beach. You will have the choice of a brand-new luxury resort or a chilled out family run resort…
