About this site
The Lagoon sits within the Koh Haa island group off the coast of Krabi in southern Thailand, an area typically reached by boat from Ao Nang or Koh Lanta. The islets enclose a sheltered inner lagoon between the limestone outcrops, and this particular site is shallow, with a maximum depth of around 2 metres over a reef bottom, making it a beginner dive. Divers have reported damselfish among the reef here.
