Scuba Diving in Lombok: Everything a Diver Needs to Know

Beneath the turquoise surface of Lombok's waters lies one of Southeast Asia's most impressive underwater worlds. The Gili Islands alone rank among the world's top ten destinations for reliable turtle encounters, while sites around Lombok's eastern coast offer dramatic reef walls, shark patrols, and fish life of staggering diversity. Whether you're completing your first Open Water course or seeking advanced drift dives on pristine reefs, Lombok delivers.

Why Dive Lombok?

Lombok sits within the Coral Triangle — the global epicentre of marine biodiversity, home to more species of coral and fish than anywhere else on Earth. The waters around Lombok benefit from the meeting of Indian Ocean currents and the Lombok Strait, creating nutrient-rich upwellings that support extraordinary marine ecosystems. Combined with exceptional water clarity (often 20–30m visibility) and warm temperatures (26–29°C year-round), the conditions for diving here are outstanding.

Top Dive Sites

Shark Point (Gili Trawangan)

Despite the intimidating name, Shark Point is one of Lombok's most popular dives — and for good reason. White-tip and black-tip reef sharks gather here in impressive numbers, resting on the sandy bottom at around 18–22 metres. These are harmless reef sharks that divers can observe at very close range. The site also features excellent coral gardens and abundant reef fish.

Turtle Heaven (Gili Meno)

As the name suggests, this site offers almost guaranteed turtle encounters. Multiple green and hawksbill turtles inhabit the reef here, and on a single dive you might encounter 5–10 individuals. The reef itself is healthy with good coral coverage and diverse fish life. Suitable for all certified divers.

Manta Point (South Lombok)

Seasonal manta ray sightings occur at various sites around Lombok's south coast, particularly during the dry season (April–October). Mantas are filter feeders and gather at nutrient-rich upwelling points. An encounter with a manta ray — with its 4–5 metre wingspan gliding effortlessly overhead — is among diving's most extraordinary experiences.

Halik Reef (Gili Air)

A beautiful sloping reef with excellent hard coral coverage, abundant soft corals, and a huge diversity of reef fish. Halik is particularly good for macro photography — look for nudibranchs, ghost pipefish, pygmy seahorses, and flatworms in the coral rubble and sea grass areas.

Simon's Reef (Gili Trawangan)

Named after a long-time local dive guide, Simon's Reef is a classic Gili T dive featuring healthy coral gardens, sea turtles, reef fish, and regular visits from schools of bumphead parrotfish. One of the most photogenic sites in the area.

Magnet (Gili Trawangan)

A dive site characterised by dramatic coral pinnacles rising from the sandy bottom. The pinnacles attract large pelagic fish including barracuda, trevally, and rainbow runners, as well as the usual complement of reef species.
