Hin Klang

A large, shallow submerged reef in the channel between the northern tip of Phi Phi Don and Bamboo Island. There is nothing above the water, so it is visited by boat on snorkelling and dive trips for its hard coral gardens, anemones and dense reef fish; currents can be noticeable, so stay close to the boat. Inside the national park.

Hin Klang is on Bamboo Island (Ko Mai Phai), the small island north east of Phi Phi Don, visited by boat trips from Tonsai.

Not that we know of. This page on kohphiphi-live.com shows what Hin Klang is and where to find it.
