Frequently asked questions

How do you get to Gili Trawangan from Bali?+
Fast boat operators (Gili Cat, Eka Jaya, Scoot Cruise) leave the ports of Padangbai, Serangan or Sanur and reach __Gili Trawangan__ directly in 1h45 to 2h30. Expect to pay 400,000-700,000 IDR (USD 25-45) per person. Book online a few days in advance during high season. In poor weather, crossings can be cancelled — build a day of flexibility into your planning, especially during the shoulder months.
Can you really see turtles snorkelling at Gili Trawangan?+
Yes — it is one of the destination's most reliable promises. Turtle Point (north-east of the island) lets you swim with green and hawksbill turtles in shore-based snorkelling, without equipment or boat. The turtles graze on the seagrass beds and are used to humans — approach slowly, keep your distance, never touch them. Scuba divers see them on virtually every dive, often at close range, around the deeper reefs.
When is the best time to visit Gili Trawangan?+
The dry season from May to September is the reference window: calm sea, exceptional underwater visibility (20-25 metres) and reliable fast-boat crossings from Bali. May and June are the most recommended months for travellers who want to avoid the summer crowds. August is the peak — the island is heaving, and accommodation needs to be locked in months ahead. September works well as an end-of-high-season window.
Should you stay on Gili Trawangan or Gili Meno?+
Gili Trawangan offers the best infrastructure (restaurants, bars, many dive schools, lively evenings) and works well for solo travellers, divers and couples who like atmosphere. Gili Meno is the most romantic and quiet — a natural choice for honeymooners or anyone wanting to escape the party scene. Gili Air sits between the two. Many travellers split their time and spend two nights on each.
Is there an earthquake risk at Gili Trawangan?+
Yes — the Lombok region is seismically active. The magnitude 7 earthquake of August 2018 hit Lombok and the Gili Islands and caused significant damage. The island has since been rebuilt and is fully operational. Get familiar with tsunami safety routes (evacuation points are signposted) and follow local alerts if you feel a tremor. Most accommodation provides a basic safety briefing on arrival.
Can you dive at Gili Trawangan without experience?+
Absolutely — __Gili Trawangan__ is one of the world's most popular places to start diving. Multiple PADI schools offer a Discover Scuba experience for around 500,000-700,000 IDR (USD 30-47) and the full Open Water course over three days for around 4,000,000-5,000,000 IDR (USD 265-330). The shallow, clear and colourful waters are ideal for first-timers, and instructors run small groups with attention to safety.
How long should you spend on Gili Trawangan?+
Two to three days are enough to take in the essentials: a day of snorkelling at Turtle Point and a full bike loop, a day of guided diving, a sunset evening on the western beach. With more time, add a day on Gili Meno (20 minutes by boat) for the contrast in pace. Divers chasing certifications or longer stays can comfortably fill five to seven days exploring every site around the three islands.

Our verdict

Gili Trawangan is one of the most appealing islands in Southeast Asia: turquoise water, accessible turtle encounters and a car-free atmosphere that turns a few days into a proper escape. High season tips the island into permanent party mode, which can grate on travellers looking for quiet — in that case, pivot to Gili Meno or Gili Air for a couple of nights. But for divers, couples and solo travellers chasing an exceptional marine setting with solid infrastructure, Gili Trawangan is one of Indonesia's reliable highlights.

The practical recipe: travel between May and September for the best conditions, with May, June and September as the strongest shoulder months. Plan two to four nights — long enough to do a couple of dives, a Turtle Point snorkel, a full bike loop and a proper sunset on the western beach. Combine Gili Trawangan with a contrasting stop on Gili Meno or southern Lombok for a more complete picture of the region. Book fast boats and accommodation early in summer, and build a half-day of flexibility into your itinerary in case a crossing gets weather-delayed. Done with a little care, the island delivers one of the cleanest, simplest island experiences in Asia.
