About this dive site

This dive site is the crescent-shaped Biaha, located on an island surrounded by a rich and dense coral reef with sections of rugged black walls and slopes. It's considered suitable for advanced divers, being the favorite of AquaMarine’s owner, Annabel Thomas. The diving experience varies between the slightly more protected southwest end of the crescent and the more turbulent north side. Inside the crescent, a small cave offers an opportunity to encounter sleeping White-tip reef sharks. A diverse marine ecosystem can be found here, including Leaf scorpionfish, cuttlefish, anglerfish, and various nudibranchs. The site’s stunning landscape and natural beauty consistently draw divers back year after year.
