Island hopping in Indonesia: how the boats actually work

Island hopping is the reason most people come to Indonesia, and the reason many of them lose two days of a two-week trip. The archipelago has three separate transport systems that do not talk to each other: fast boats run by private companies, public ferries run by ASDP, and a dense web of domestic flights on Lion, Garuda, Citilink and Batik. None of them publishes a combined timetable, and the websites are often out of date.

The good news is that the main tourist route is short and well served. Bali to Lombok to the Gilis is a morning's travel, and Bali to Flores is a flight plus a drive. The bad news is that anything beyond that, Maluku, Papua, the Banda Islands, involves a Pelni ferry that runs twice a month and a level of patience that most holidays cannot afford.

The three ways to cross water

Fast boats are the tourist default. They are catamarans or converted fishing boats that run fixed routes between Bali, Lombok, the Gilis, Nusa Penida and the Gili Islands, taking one to two and a half hours. They are comfortable enough, cost IDR 250,000 to 600,000 each way, and are the only sane option if you have limited time. They are also the first thing cancelled when the sea picks up.

Public ferries are the local system: big, slow, cheap and frequent on the main crossings. The Padangbai to Lembar ferry takes four to five hours and costs around IDR 60,000 for a foot passenger. The Ketapang to Gilimanuk crossing between Java and Bali takes an hour. They run through the night, they rarely cancel, and they are a genuine slice of Indonesian life.

Flights cover the long distances. Bali to Labuan Bajo is 1.5 hours, Bali to Lombok 25 minutes, Jakarta to Medan two hours. Domestic fares are low if you book a few weeks ahead, but baggage allowances are tight and delays are routine in the wet season. For anything over 300 kilometres, flying usually costs less than the time you save.

• Fast boat: 1-2.5 hours, IDR 250,000-600,000
• Public ferry: 1-5 hours, IDR 20,000-60,000
• Domestic flight: 25 minutes to 2 hours
• Pelni ship: days, not hours

The classic route: Bali, Lombok, the Gilis

This is the route almost every first-time island hopper takes, and it works because the distances are short. Start in south Bali, take a fast boat from Padangbai or Sanur to Gili Trawangan or Gili Air, spend three nights, then take the 20-minute local boat to Lombok and base yourself near Kuta Lombok or Senggigi for the surf and the south coast.

The alternative is to go overland: bus or car from Bali to Padangbai, ferry to Lembar, then drive to Kuta Lombok in about two hours. That route costs a fraction of the fast boat and lets you stop at the beaches along the way, but it takes a full day. Coming back, most people fly Lombok to Denpasar for IDR 700,000 to 1.2 million and save the return crossing.

Book the fast boat through your hotel or a reputable agent, not a man with a laminated sign at the port. Confirm whether you leave from Sanur or Padangbai, because they are an hour apart, and check the weather on the morning of travel. In July and August the afternoon boats are often rough, so take the early one.

Eastward: Flores, Komodo and Sumba

Flores is the next step and the reward is Komodo National Park. Fly Bali to Labuan Bajo, which takes 1.5 hours and costs IDR 700,000 to 1.5 million, then take a day boat or a two-night liveaboard to Padar, Komodo and Pink Beach. Labuan Bajo itself has become a busy little town with dive shops, rooftop bars and a harbour full of phinisi boats.

Overland Flores is a different trip altogether: Ruteng, Bajawa, the Kelimutu coloured lakes and the villages around Ende, connected by a road that is beautiful and slow. Allow a week. Sumba, further south, is reached by a short flight from Bali and offers empty beaches, ikat weaving and a handful of high-end resorts. It is not a place to hop through; it is a place to stay.

The Banda Islands and Raja Ampat are the far end of the scale. They involve multiple flights plus a ferry or a liveaboard, and the reward is some of the least visited water on earth. If you have two weeks and want to see them, do not try to combine them with Bali. Pick one region and go deep.

• Bali to Labuan Bajo: 1.5 hours by air
• Komodo day boat: IDR 1-2 million
• Two-night liveaboard: IDR 3-6 million
• Overland Flores: allow a week

What it costs and how to book

Inter-island transport is the one part of an Indonesian trip where a little planning pays. A two-week hop through Bali, the Gilis, Lombok and Flores costs roughly USD 250 to 450 per person in transport: two domestic flights, three fast boats, a ferry and a few drivers. The same route on public transport and buses can be done for under USD 100 if you accept the time cost.

Book domestic flights on the airline app or Traveloka, and pay with a card that does not charge a foreign transaction fee. Book fast boats through your accommodation, which usually gets a better rate and knows which company is reliable that week. For ferries, buy at the port on the day; there is no advantage to booking ahead and the queues are part of the experience.

Keep your plans loose at the end of the trip. Boats and flights in eastern Indonesia are cancelled often enough that a same-day connection to an international flight is a gamble. A buffer night in Bali or Jakarta costs less than a rebooked long-haul ticket.

Seasons, safety and the plain truth

The dry season from April to October is the time to hop. Seas are calmer, boats run on schedule and the visibility is better for diving. The wet season does not close the routes, but the crossings are rougher and cancellations become common in January and February. If you travel then, book morning boats and keep a spare day.

Safety standards vary. Fast boats are regulated and generally fine, but life jackets are sometimes stored rather than worn, and overloaded ferries are a real risk around the major holidays. Avoid the cheapest boat if the weather is marginal, sit near an exit, and never take a night crossing on an unlicensed vessel. The sea between the islands is not a swimming pool.

The plain truth is that island hopping is tiring. Every move costs half a day of packing, transfers and waiting. The travellers who enjoy it most move less than they planned: three islands in two weeks, not six. Indonesia rewards depth, and the best moments usually happen on the third day in a place you almost skipped.

• Dry season: April to October
• Take the morning boat, always
• Avoid overloaded ferries at holidays
• Three islands in two weeks is plenty

Questions people actually ask

What is the best island-hopping route in Indonesia?

Bali, Nusa Penida, the Gilis and Lombok in two weeks, with an optional flight to Flores for Komodo. It is short, well served and easy to book.

Are fast boats safe in Indonesia?

The licensed operators are generally fine, but standards vary. Avoid the cheapest boat in rough weather, check for life jackets and prefer morning crossings.

How far in advance should I book?

Domestic flights a few weeks ahead, fast boats a day or two ahead, and ferries on the day. July, August and Christmas need more lead time.

Can you island hop on a budget?

Yes, using public ferries and buses. It costs a fraction of the fast boats but takes two to three times as long, so it suits a month-long trip rather than a fortnight.
