Halik is a sloping reef available to all divers. Beautiful coral formations are found in the shallows, and along the reef coral bommies, gorgonian fans and barrel sponges are intensely inhabited with hundreds of species of reef fish. A perfect drift dive, and commonly Lionfish, Moray Eels, Coral Grouper, andBumphead Parrotfish (around the full moon) are to be found. Green and Hawksbill turtles inhabit the reef, and cephalopods are abundant in the nooks and crannies.
For the more experienced diver, there is Deep Halik, a series of coral canyons perfect for a multilevel dive. The coral is pristine, and Reef Sharks, Eagle Rays, Manta Rays are often seen during wet season and barracuda tornado school in the deeper trenches.
One of the most varied and interesting dive sites around the Gili's, Andy's is a vast open site available to all levels of diver certification. The site starts with a shallow sloping reef, with a series of ridges and valleys leading into deeper water.
Shark Point is one of the most popular sites of the Gilis situated at approximately 28m. An impressive variety of marine life inhabits this reef with White-tip and Black-tip Sharks, Jacks, Trevally, Fusilier, Angelfish, Snapper, and Blue Spotted Stingrays all commonly seen.
This site is a gently sloping reef. The reef ends in a sandy bottom beyond about 20m and has a flat reef top about 3-5m. The site is rich in many varieties of coral - Staghorn, Plate Acropora, Brain, Star, Elephant Ear, Leather and a good variety of soft corals and anemones. The fish population is diverse, including lots of Sweet Lips, Groupers and Snappers, many Damselfish and Basslets, a good number of Angelfish of different varieties, Parrotfish, and Butterfly fish. Sunset is one of the best sites to see Manta Ray between December and February as they skim the plankton rich shallows. White-tip Reef Sharks inhabit the flat sandy areas around 18m and the occasional Black-tip will swim through the shallows.
BioRock Technology was brought to the island 7 years ago and the BioRock Reef is now home to several of the islands reef regrowth structures. Electric currents attract coral spawn and limestone particles to steel structures in various sizes and shapes along the 6-12m slope. Juvenile corals are thriving in these artificial environments and smaller reef fish take refuge in the shelter of these structures. Filefish, Boxfish, Cowfish, Bannerfish and Moorish Idols are common along with Frogfish, Pipefish and the occasional Crocodile fish. Much research is undertaken along these reefs and often divers are able to watch as measurements and statistics are taken.
Goodheart Reef begins in Shallow Turbo and runs parallel to the East Coast of Trawangan. Gently sloping from the shore into deeper water, coral bommies and outcrops protrude from sandy areas, each thriving with smaller species and juveniles seeking the shelter of shallow shore waters. Damsels, Butterflyfish, Antheas and Angels in great numbers can be found along with Cuttlefish and Octopus.
This is a huge dive site available to divers with Advanced Open Water onwards. An abundance of large coral bommies. or hills covered in soft and hard corals, Deep Turbo will interest divers as exploring the reef and its marine life makes for a fascinating dive. The majority of the dive is around 20-30 meters, with the opportunity to multi-level the dive at the top of the bommies.
