Gili Biaha Dive Site
is island of rock, with a rounded cap of grass and it is the most remote of the Amuk Bay sites, located about four kilometres northeast of Tepekong. It is a beautiful steep drop-off reef, nicely fissured and terraced in places, rings most of the island, going to a slope in the north. The inside of the island’s curve is always protected from the current, but heavy swell can make things worse up near the reefs wall face, particularly for your boat captain who picks the divers up. End of the rugged and terraced reef wall will lead into blowhole where a number of Reef Sharks can always be found under the overhang of the blowhole wall, inside also lives abundance of lobsters in between the cracked wall.
To dive into blowhole should you carry a quality light, inside it is really dark. There are swarms of reef fishes at this site, the beautiful Mayer’s Butterfly fish are rare through out of Bali reefs, is common in this site. It is the only possible penetrating into blowhole when a small surge laps the reef wall and water is pounded out from blowhole. The swirling current can occur at some places of the site, to be safe, is to stay close to the reef wall face and ascend a little distance from the reef wall face. The water temperature dips as below as 20 degrees C, so get ready with the proper wet suit to stay warm.
