Thailand :: Koh Lanta : Koh Hah

A group of five islands around 25km west of Koh Lanta separated by deep water channels. There are six different places to dive here and visibility is usually good. Marine life is plentiful here with all the regular visitors including morays and nudibranchs with the bigger tuna, jacks and trevally hunting in the deeper waters. There is a series of caves at the largest island, Koh Hah Yai, where natural light filters into a large underwater chamber. The entrance is at about 12 meters and you can actually surface inside to view some spectacular overhanging stalagtites.
