Reef Sharks and Turtles Around the Gili Islands: A Diver’s Paradise
The Gili Islands, just off the coast of Lombok, are among Indonesia’s most stunning natural gems. Known for their pristine beaches, turquoise waters, and laid-back island vibe, the Gili Islands are the perfect destination for those seeking a slice of paradise. But beyond the beautiful sunsets and vibrant nightlife, there lies a whole other world beneath the surface that is equally mesmerizing. Reef sharks and turtles abound in the waters surrounding the Gilis, making it one of the premier spots for snorkeling and diving enthusiasts.
If you are planning a holiday in the Gili Islands, experiencing the underwater life is an absolute must. Whether you choose to snorkel with one of the local operators or take the plunge with a dive center like Oceans 5 Gili Air, exploring the marine life here will leave you in awe. The Gili Islands offer some of the best opportunities to see both Hawksbill and Green Sea Turtles as well as the elusive yet captivating reef sharks. Let’s take a closer look at these fascinating creatures and where you can best encounter them.
The Turtles of the Gili Islands: Gentle Giants of the Reef
One of the most iconic sights in the waters surrounding the Gili Islands is the sea turtles. There are two types of turtles you are likely to encounter during your underwater adventure—the Hawksbill Turtle and the Green Sea Turtle. These gentle giants are easy to spot and are present in almost every snorkeling and dive site around the Gili Islands.
Green Sea Turtles
The Green Sea Turtle is perhaps the most commonly encountered species around the Gilis. Named for the greenish hue of their fat, which comes from their herbivorous diet, these turtles can be seen gracefully gliding through the water or feeding on sea grass. With their calm demeanor, they are often unperturbed by the presence of divers or snorkelers, allowing for an incredible up-close experience.

Green Sea Turtles are often spotted at popular snorkeling spots like Turtle Point, which is located just off the shores of Gili Trawangan. This spot is perfect for those new to snorkeling, as the turtles are easy to find and often rest in shallow waters, making it ideal for viewing.
Hawksbill Turtles
Hawksbill Turtles are also frequently found in the waters surrounding the Gili Islands. Unlike the Green Sea Turtle, Hawksbill Turtles have a more distinct, pointed beak, which they use to feed on sponges and other invertebrates found in coral reefs. Their beautiful, intricately patterned shells make them a favorite among underwater photographers.
These turtles are often found on reef sites where coral is abundant. Hawksbill Turtles are an essential part of the ecosystem, as their feeding habits help maintain the health of coral reefs by controlling sponge populations. In the Gilis, you can spot Hawksbill Turtles at many dive sites, including Turtle Heaven near Gili Meno, which is known for its excellent visibility and abundant marine life.
Encountering Reef Sharks: The Thrill of the Dive
For those seeking a little more thrill during their underwater exploration, diving with reef sharks around the Gili Islands is an unforgettable experience. The waters around the Gilis are home to two main species of reef sharks—the Blacktip Reef Shark and the Whitetip Reef Shark. Unlike their larger cousins, these sharks are relatively small and pose no threat to humans. In fact, encountering these sleek predators in their natural habitat is a highlight for many divers.
Blacktip Reef Sharks
Blacktip Reef Sharks are easily recognizable by the distinct black tips on their dorsal and tail fins. They are agile swimmers and are often found in shallow waters, making them a common sight during dives around the Gilis. Blacktips are curious creatures and may approach divers, though they are generally shy and quick to swim away.
The best places to see Blacktip Reef Sharks around the Gilis are the dive sites of Halik and Sunset Reef, both located off the coast of Gili Trawangan. These sites are known for their gentle currents and excellent visibility, providing an ideal setting for spotting these beautiful creatures as they patrol the reef.
Whitetip Reef Sharks
Whitetip Reef Sharks, on the other hand, are more commonly found resting on the sandy bottom during the day. They are nocturnal hunters, which means they are more active at night, but divers can still encounter them resting under ledges or in crevices during daylight dives. Whitetip Reef Sharks are slender, with a characteristic white tip on their dorsal fin, and they can often be found in slightly deeper waters compared to their blacktip counterparts.

Sharkpoint, a dive site aptly named for its frequent shark sightings, is one of the best spots to encounter Whitetip Reef Sharks. Located near Gili Trawangan, Sharkpoint offers divers the chance to see these sharks resting or slowly cruising along the reef, often accompanied by schools of colorful fish.
The Best Dive Sites for Shark and Turtle Encounters
The Gili Islands boast an array of dive sites suitable for all experience levels, from beginners to advanced divers. Here are some of the best sites to visit if you want to see reef sharks and turtles during your dives:
- Turtle Heaven: Located near Gili Meno, Turtle Heaven lives up to its name, with an abundance of Green and Hawksbill Turtles. The shallow depth and gentle currents make this site perfect for both snorkelers and beginner divers. The site features a vibrant coral garden where turtles can often be seen feeding or resting.
- Sharkpoint: As the name suggests, Sharkpoint is one of the best places to see Whitetip Reef Sharks in the Gilis. The dive begins with a gentle slope covered in coral, eventually leading to a sandy bottom where sharks can often be seen resting. This site also features large schools of snapper, trevally, and sometimes even eagle rays.
- Halik: Halik is a dive site located off the northern coast of Gili Trawangan. It is known for its beautiful coral formations and diverse marine life, including Blacktip Reef Sharks. The site has a mix of shallow and deeper areas, making it suitable for a range of diver experience levels. With its clear waters, Halik is a great spot for underwater photography.
- Sunset Reef: Situated off the west coast of Gili Trawangan, Sunset Reef is a fantastic site for spotting Blacktip Reef Sharks. The best time to dive here is during the afternoon, as the sun begins to set, giving the site its name. In addition to sharks, divers can also expect to see a wide variety of reef fish, moray eels, and the occasional turtle.
