Compare the operators
Boat, luggage allowance and check-in for each operator. We ask every operator for life jackets in adult and child sizes, a marine radio and passenger insurance.
At your operator's office on Jl. Pantai, the main strip on the east coast, 30 minutes before departure. Bring your passport and QR e-ticket; the staff tag your bags and call the boat when it is ready. There are no motor vehicles on Gili T, so walk, cycle or take a cidomo with your luggage, and agree the price before loading. Pay the harbour fee of about IDR 10,000 to 20,000 in cash. You board from the beach or the floating jetty depending on the tide, so keep sandals on until you are seated, and your phone in a dry bag. Boats from Gili T sometimes call at another island first, and the crew will tell you when to board. Give the cidomo driver your operator's name; the offices are close together on the strip.
What is it like landing at Serangan?
Serangan lands by jetty, so you usually step off with dry feet and wheel your bag straight to the car park. The harbour is quiet compared with Sanur and Padang Bai, and it is 20 to 30 minutes from Kuta, Seminyak and Sanur outside rush hour. Some fares on this route include a hotel transfer in south Bali, which the timetable marks; the driver meets you at the operator's office. Otherwise taxis and ride-hailing cars come to the harbour, though it can take a few minutes to get one in the afternoon. If you have a flight the same day, leave a generous buffer, as weather can delay sailings. If you are heading to Nusa Penida later, Serangan also has boats to Buyuk on some days of the week.
Is the Lombok Strait rough?
It can be. The Lombok Strait is deep and open to the Indian Ocean swell, so it moves more than the short hop to Nusa Penida. The calmest months are usually April, May and October; July and August bring the biggest swell. Morning departures are usually smoother than afternoon ones. If you get seasick, take a tablet 30 to 60 minutes before departure, sit in the middle or rear of the lower deck, look at the horizon and skip a heavy breakfast. Keep a light jacket handy, as air-conditioned cabins can be cold. When the harbour master issues a weather warning, sailings are suspended; if your boat is cancelled, you can move to the next departure for free or get a full refund, and we message you on WhatsApp as soon as we know.

The Lombok Strait is deeper and more exposed than the Badung Strait, so Gili crossings move more. April, May and October are usually the calmest months; July and August bring the biggest swell. Morning sailings are usually smoother, and the harbour master suspends crossings when a weather warning is issued. General guidance, not a forecast.

Gili Trawangan to Serangan: questions travellers ask
How long is the fast boat from Sanur to Nusa Penida?
About 40 minutes (30–45 depending on the operator and the sea). Sanur to Nusa Lembongan is about 35 minutes. Padang Bai to Gili Trawangan takes about 1.5 hours, and Sanur or Serangan to the Gilis 2¼–3½ hours with stops.
What time should I check in?
Be at your operator's counter 30–45 minutes before departure with your QR e-ticket and passport. If you added hotel pickup, we send the exact pickup time on WhatsApp the evening before.
How much luggage can I bring?
Usually one bag up to 20–25 kg plus a small hand bag per passenger. Surfboards, bikes, dive gear or extra bags may cost extra — add them as an extra when booking. Porters load bags into the hold or onto the roof, so keep your passport, phone and valuables with you.
Is it safe? Are there life jackets?
We ask every operator we work with for life jackets in adult and child sizes and a radio on board. Check the safety equipment listed on each boat before you book, listen to the crew briefing and wear your life jacket when asked. Crossings are suspended when the harbour master (Syahbandar) issues a weather warning.
I get seasick. Any tips?
Take seasickness tablets 30–60 minutes before departure, sit in the middle or rear of the lower deck, look at the horizon and skip a heavy meal. Morning crossings are usually calmer. The Lombok Strait (Gili routes) is rougher than the Badung Strait (Penida and Lembongan).
What happens if my boat is cancelled because of weather?
If the harbour master or the operator cancels a sailing, we move you to the next available departure free of charge or give you a full refund — your choice. We contact you on WhatsApp as soon as we know.
Are island taxes and harbour fees included in the ticket price?
No — they are paid locally, not to us. Budget for the Bali tourist levy IDR 150,000 (pay at lovebali.baliprov.go.id), the Nusa Penida / Lembongan island fee IDR 25,000 per adult and IDR 15,000 per child (cashless), about IDR 25,000 per major Penida attraction, and harbour fees of about IDR 10,000–20,000 in cash at Padang Bai, the Gilis and Bangsal.
Can I go directly from Nusa Penida or Lembongan to the Gili Islands?
Yes. Operators such as Eka Jaya, BlueWater Express, Semaya One and The Tanis run direct island-to-island boats in about 1¾–2¾ hours, so you don't need to go back to Bali.
