About Gili Air

Map of Bali and Lombok islands in Indonesia, showing major towns and geographic locations.

Gili Air is the smallest and most relaxed of the Gili Islands, located just off the northwest coast of Lombok, Indonesia. Known for its crystal-clear waters, abundant marine life, and no-motor-vehicle policy, it offers a truly unspoiled dive experience. Depths range from 5m to 30m+, with visibility frequently exceeding 20m. The island sits at the heart of the Coral Triangle, making it one of the world’s most biodiverse marine environments.

Dive Sites

  • On the west side of Gili Air, Air Wall has something for everyone with its diverse topography - a gentle sandy slope with colorful coral bommies transitioning into a wall. Turtles rest here alongside cuttlefish and clownfish, while stingrays and garden eels hide in the sand. Parrotfish, angelfish, triggerfish, sweetlips, and whitetip and blacktip reef sharks are also commonly seen.

  • Nestled on the north of Gili Meno, Turtle Heaven offers amazing encounters with large green and hawksbill turtles. A pinnacle reaches up to 10m making it accessible for beginners, while it drops to 35m for deeper divers. Nudibranchs, pipefish, frogfish, and crustaceans can all be found here.

  • A coral reef plateau at 10m follows the north side of Gili Trawangan before sloping down to 18m, transforming into rolling valleys and canyons that extend to 35m. Numerous green sea turtles inhabit the shallows, with juvenile whitetip reef sharks sheltering beneath bommies at depth. The deliberately sunk Glenn Nusa Wreck adds an extra draw. Currents can be strong around new and full moons — best for intermediate to advanced divers.

  • Located further from shore, the shallowest point is around 18m, dropping through huge pinnacles and ridges covered in gorgonians and coral formations - like underwater skyscrapers. Reef sharks, stingrays, and an abundance of nudibranchs are regularly encountered. Advanced divers only due to depth and currents.

  • Located in the channel between Gili Air and Gili Meno, divers drop onto a plateau at roughly 12m and drift along as the reef grows gradually deeper. For a deeper dive, a sloping reef wall reveals trevally, large snappers, Spanish mackerel, and barracuda. Suitable for all levels and considered a must-dive.
