Koh Ha - Caverns diving
Ko Ha is a small group of islands almost directly west of Ko Lanta. These tiny islands, separated by channels over 50 meters deep, jut straight out of the Andaman Sea. However, unlike at Phi Phi, the water here is ordinarily quite clear and visibility frequently exceeds 25 meters.
The highlight of diving here is a series of caves, or caverns on the largest of the islands, Ko Ha Yai. The caves are safe to enter, even without a light, as the entrances are large and there is only one way in and one way out.
The best part of entering these caves is that you can surface inside the island to view stalactites hanging down from the ceiling over 30 meters above the surface. The quality of light filtering through the water from the entrance is magical.
At these Dive Sites you'll have the opportunity to see many types of fantastic pelagic creatures such as Manta Rays or even the giant of the fishes - the Whale Shark.
