The Dive Sites Koh Lanta

The dive sites surrounding Koh Lanta truly have something to offer everyone.  From secluded to lagoons to the deepest drop off in Thailand - Koh Lanta has something amazing to offer for all levels of diving & snorkelling.  Find out more on our famous dive sites below.  

Koh Haa

Koh Haa to the west is our closest collection of Dive Sites - taking us just a little over an hour to reach due to our southerly departure point in Klong Nin.  Koh Haa is a group of 5 islets suitable for both diving and snorkeling. This area is home to about 12 great dive sites, and it is quite common to experience 30m+ visibility here.

A beautiful lagoon area is perfect for first-time diving and courses, where you can see anything from ornate ghost-pipefish and harlequin shrimps to turtles, barracudas and even Whalesharks.  More experienced divers can experience deeper sites, undersea caverns and stunning swim-throughs - the most famous being the 'cathedral' at Koh Haa Yai - where the huge cave entrances make it possible to enter without lights, and even surface inside the island where beautiful limestone formations form a 'cathedral' like ambiance.

Schooling tunas and trevally hunt beside rainbow runners and barracuda.
