MARINE LIFE & DIVE SITES
Gili Islands Marine Life: Turtles, Reefs & Dive Sites
From resident green and hawksbill turtles to named dive sites like Turtle Heaven and Meno Wall — what actually lives on the reefs around the Gili Islands.

Three tiny islands barely a few kilometres apart share one connected reef system, and the diving punches well above what the islands' size suggests. Coral gardens ring the shallows close to shore before sloping into deeper terrain further out, giving both brand-new divers and experienced ones a reason to get in the water. What draws most people back, dive after dive, isn't a single showpiece site but the sheer consistency of the encounters — turtles on nearly every dive, healthy fish life, and a reef that, in the areas actively looked after, has visibly recovered from decades of pressure.
The turtles
Green and hawksbill sea turtles are the signature sighting, and they're common enough that the islands are sometimes described as one of Southeast Asia's best places to see them reliably rather than by chance. Green turtles graze on seagrass and algae in the shallows and are often seen resting on the reef, apparently unbothered by nearby divers; hawksbills favour coral crevices, using their narrow beaks to feed on sponges. Local dive operators and conservation groups have tracked returning individuals over the years, and some turtles are recognisable enough by shell markings that regular divers and instructors start to know them by sight.
Reef sharks, rays and the smaller stuff
Beyond turtles, the reefs support blacktip reef sharks — small, shy and harmless to divers — along with occasional rays resting on sandy patches. Look closer and there's plenty more: cuttlefish that change colour as you approach, moray eels tucked into crevices, nudibranchs on the coral, and dense schools of reef fish moving over the coral gardens. None of this is guaranteed on any single dive — reef life varies with the site, the season and a bit of luck — but the density of sightings across the three islands is a big part of why the Gilis have such a strong diving reputation for their size.
Named dive sites worth knowing
Local dive centres refer to a set of named sites scattered around the three islands, each with its own character — a shallow, current-light site sometimes called Turtle Heaven or Turtle Point for its consistent turtle sightings; deeper sites off Gili Meno, including a wall dive generally known as Meno Wall, that step down into cooler water; and current-swept sites such as Deep Turbo and Halik, better suited to certified divers comfortable with drift conditions. Naming and exact boundaries vary a little between operators, so treat these as the kind of local shorthand a dive briefing will confirm on the day rather than a fixed, official map.
The underwater statues
One of the more unusual sights in Gili waters is a cluster of underwater sculptures installed as part of a coral-restoration effort, generally referred to locally by names including Nest — human figures arranged on the seabed that double as a frame for coral to grow on over time. It's the kind of installation that turns a dive into something closer to visiting a slowly changing artwork: bare on installation, then increasingly colonised by coral and small reef life as the years pass. Ask your dive centre which sites currently include the sculptures, since access and exact positioning can shift.
Reading the reef without damaging it
Good buoyancy control matters more here than technical skill — a fin kick that clips live coral can undo years of growth in an instant, and reef damage is one of the main things local conservation groups are actively trying to reverse. Keep hands off the reef, avoid resting on coral even briefly, and give turtles space rather than chasing them for a closer photo; they'll often continue feeding calmly if left alone. A short buoyancy refresher before your first dive, which reputable centres build into their briefing, pays off in both safety and how much marine life you actually get to see.
