Scuba Diving Gili Islands
Three tiny islands off Lombok with crystal-clear water, resident sea turtles, reef sharks, and some of the cheapest PADI courses on the planet.
1 day in Scuba Diving Gili Islands
Only got 24 hours? Here's how to experience the best of Scuba Diving Gili Islands in a single action-packed day.
Two Fun Dives & Beach Snorkelling
Shark Point & Turtle Heaven
Meet your dive boat at the harbour by 7:30am for the first dive at Shark Point — a sloping reef where blacktip and whitetip reef sharks patrol the sandy bottom at 18–25m. The reef is covered in hard and soft corals teeming with fusiliers, sweetlips, and giant trevally. After a surface interval on the boat with tea and fruit, descend at Turtle Heaven — a gentle slope of coral bommies where green sea turtles rest and feed. You will almost certainly see multiple turtles here. Two-dive trips cost around Rp 900,000–1,200,000.
Halik Reef & Beach Snorkelling
After returning to shore and grabbing a Nasi Goreng lunch for Rp 25,000–40,000, walk to the east coast of Gili Trawangan where turtles come right up to the shallows. The snorkelling here is free — just walk in from the beach with a mask and snorkel. The coral starts a few metres from shore and green turtles graze on seagrass in waist-deep water. Halik Reef, accessible from the northeast shore, has the densest turtle population on the island.
Sunset & Night Market
The west coast of Gili Trawangan faces directly into the sunset with Mount Agung on Bali silhouetted against the sky — one of the most photographed sunsets in Indonesia. Grab a bean bag at a beach bar, order a Bintang beer (Rp 35,000), and watch the sky turn orange. After dark, the night market near the main strip serves fresh grilled seafood — pick your fish from the ice display and they grill it for Rp 50,000–80,000 with rice and sambal.
3 days in Scuba Diving Gili Islands
A carefully curated route mixing iconic landmarks, hidden gems, street food, culture, and adventure — designed for younger travelers.
PADI Open Water — Pool Session & Theory
Course Sign-Up & Knowledge Development
Day one of the PADI Open Water course begins with knowledge development — watching videos, reading the manual, and completing quizzes at your dive shop. Most shops on Gili Trawangan run courses daily with groups of 2–4 students per instructor. The course costs Rp 5,500,000–7,000,000 and includes all equipment, certification fees, and usually 3 nights of basic accommodation. Compare shops in person — prices vary and equipment quality differs significantly between operators.
Confined Water Session — First Breaths
The afternoon confined water session takes place in a pool or shallow bay. You will learn to assemble your gear, breathe underwater for the first time, clear your mask, recover your regulator, and practise buoyancy control. The sensation of breathing underwater for the first time is unforgettable. Your instructor will run through each skill multiple times until you are comfortable. This session typically lasts 2–3 hours.
Study & Island Exploration
Complete the remaining knowledge review chapters and prepare for the theory exam. The Gili Islands have no motorised vehicles — the soundtrack is horse carts, bicycles, and reggae. Rent a bicycle (Rp 50,000/day) and ride the flat 7km loop around Gili Trawangan in 45 minutes, stopping at quiet beaches on the east coast. Dinner at a warung on the main strip — Nasi Campur for Rp 30,000–45,000.
Open Water Dives 1 & 2 — Into the Ocean
Open Water Dive 1 — First Ocean Dive
Your first real ocean dive takes place at a sheltered site with gentle currents and good visibility. At 8–12m depth, you will repeat confined water skills on the sandy bottom while surrounded by reef fish, coral, and potentially your first turtle sighting. The Gili Islands have exceptional visibility — 15–25m on good days — making them ideal for learning. Your instructor stays within arm's reach at all times.
Open Water Dive 2 — Deeper Skills
The second open water dive goes slightly deeper (12–18m) and introduces navigation, deeper equalisation, and more advanced buoyancy skills. The reef life at this depth is richer — look for nudibranchs, moray eels tucked into crevices, lionfish, and schools of fusiliers. You will also practise a controlled emergency swimming ascent, an essential safety skill. After two dives, most students feel significantly more comfortable underwater.
Theory Exam & Sunset
Complete the PADI theory exam at the dive shop — 50 multiple choice questions covering dive physics, physiology, equipment, and planning. Most students pass first time if they have studied the material. After the exam, reward yourself with sunset drinks at a beach bar. The post-exam feeling of relief combined with a Gili sunset is hard to beat. Fresh grilled fish at the night market for dinner.
Open Water Dives 3 & 4 — Certification Day
Open Water Dive 3 — Reef Sharks & Coral Gardens
Dive three takes you to one of the Gilis' premier sites. At Shark Point, blacktip reef sharks glide along the sandy channels between coral bommies at 18–22m. You will also practise underwater navigation using a compass and natural references. By now your buoyancy should be noticeably better — you will use less air and move more gracefully. The marine life on the Gili reefs is extraordinary for such shallow, accessible sites.
Open Water Dive 4 — Certification Dive
Your final certification dive is the most enjoyable — fewer skills to demonstrate and more time to simply explore the reef. Your instructor will sign off remaining skills and then lead a guided tour of the site. Turtles, reef sharks, octopus, cuttlefish, and colourful reef fish are all common. When you surface from dive four, you are a certified PADI Open Water diver — qualified to dive independently to 18m anywhere in the world.
Celebration & Gili Nightlife
Celebrate your certification at one of Gili Trawangan's famous beach parties. Monday and Wednesday nights are the biggest party nights, with bars along the main strip hosting DJs and fire dancers. If you prefer something quieter, Gili Air has mellower beach bars with live acoustic music. Many dive shops offer discounted fun dives for newly certified divers — book a two-dive trip for the next morning before you leave the islands.
Budget tips
Compare dive shops in person
Walk along the main strip on Gili Trawangan and compare prices at 3–4 shops. Prices vary by Rp 500,000–1,000,000 for the same PADI course. Ask about equipment age, instructor ratios, and included accommodation.
Free snorkelling with turtles
You do not need to pay for a snorkel tour. Walk into the water on the east coast of Gili Trawangan with a mask and snorkel (rent for Rp 30,000/day) and see turtles in waist-deep water for free.
Eat at warungs, not restaurants
Local warungs serve Nasi Goreng, Mie Goreng, and Nasi Campur for Rp 25,000–40,000. Tourist restaurants on the strip charge Rp 80,000–150,000 for the same dishes with a sea view.
Book fast boat from Bali online
Fast boats from Padang Bai or Serangan to Gili Trawangan cost Rp 200,000–400,000 booked online, versus Rp 500,000+ at the harbour. The trip takes 1.5–2.5 hours depending on the operator.
Choose Gili Air for cheaper stays
Gili Air has fewer tourists and lower prices than Gili Trawangan. Guesthouses start at Rp 150,000/night versus Rp 250,000+ on Gili T. The diving is equally good with fewer boats on the sites.
Bring your own gear
If you already own a mask, snorkel, and rash vest, bring them. Equipment rental adds Rp 100,000–200,000 per day and rental masks are often scratched or ill-fitting.

Cultural tips
The Gili Islands are a fragile marine ecosystem on Muslim Lombok — respect both the ocean and the local culture for the best experience.
Protect the Turtles
Do not touch, ride, or chase sea turtles — they are endangered and protected by Indonesian law. Maintain a 2m distance and let them approach you. Report any dive shop that allows turtle harassment.
Reef Conservation
Never touch, stand on, or break coral — even dead-looking coral is alive. Maintain good buoyancy to avoid fin kicks on the reef. Choose dive shops that participate in reef conservation programmes like Gili Eco Trust.
Respect Local Culture
The Gili Islands are part of Muslim Lombok — dress modestly when visiting local areas away from the tourist strip. Remove shoes before entering mosques or homes. During Ramadan, eat and drink discreetly during daylight hours.
Language
Learn basic Indonesian — Terima kasih (thank you), Berapa harga? (how much?), and Selamat pagi (good morning) are appreciated. Dive briefings are in English but local interactions benefit from a few words of Bahasa.
Support Local Operators
Choose locally-owned dive shops and warungs over international chains. Many dive instructors are Indonesian — supporting local operators keeps tourism revenue in the community.
Reduce Plastic Waste
The Gili Islands have a serious waste problem. Bring a reusable water bottle, refuse plastic straws, and take your rubbish with you. The Gili Eco Trust runs regular beach clean-ups — join one if you have time.
