This group of stunning and remote islands is situated about half an hour boat trip from AquaScuba’s Dive Center in koh Lanta. (Haa means 5 in the local dialect and since Koh Haa is actually made up of six small islands someone must have miscalculated!).

This is one of our favorite destinations. Five (?) beautiful limestone islands with a shallow lagoon and white powder beach above the surface, and a magical diving experience both for beginners as well as experienced divers. The islands are separated by deep water channels, and are famous for the exceptional visibility. With a choice of at least six dive sites, provide excellent diving for all levels of diver. Here you will find colorful coral gardens and fringing reefs, impressive walls, strange pinnacle formations, and huge cathedral like caves.

The marine life that can be found at Koh Haa varies from rare Ghost Pipefish measuring only a few centimeters, to an abundance of Porcupine fish, lionfish and Octopus hiding amongst the rocks and crevices. A Hawksbill Turtle is often seen swimming amongst the pristine coral. You can also find banded sea snakes, lionfish, crustaceans and beautiful cowries. Huge schools of silverside fish, glassfish, and barracudas abound. While Manta Rays, Eagle Rays and even Whale Sharks are spotted here occasionally. You can’t predict exactly what you’ll see, but it’s always a pleasant and rewarding surprise!

One of Koh Haa’s highlights is the series of caverns and swim-throughs. The largest cavern has three chambers. The first two chambers are connected by a shallow swim through at about 9 meters. There are also various chimneys and other systems for the more experienced divers to explore.

Our favorite is a cave with two entrances one at a depth of 5 meters and the other at 16 meters. The light finds its way in and creates a magical atmosphere by reflecting on the resident glass fish. When you are inside this cave you always have open water above (i.e. you can surface at any time) so all certified divers can safely dive here.

The clear waters and consistent visibility of 25m+ make Koh Haa an un-forgettable diving and snorkeling destination.
