Marina Ancol: The Speedboat Option

Marina Ancol, part of the larger Ancol tourism complex in North Jakarta, is where most speedboats to the Thousand Islands depart. Fares scale with distance: expect roughly Rp110,000–155,000 one-way to the nearest islands such as Bidadari and Ayer, Rp175,000–215,000 to mid-distance islands such as Tidung, Pari and Pramuka, and Rp305,000–335,000 or more to farther resort islands such as Pelangi, Sepa, Harapan and Kelapa. Crossing times generally run from under an hour for the closest islands to around two hours for the farthest ones, weather and boat type permitting. Several operators run from the same marina, so it is worth comparing departure times rather than assuming only one schedule exists; see the official archipelago overview for a sense of the full route network.

Boats are typically open-sided or semi-enclosed speedboats seating anywhere from a dozen to several dozen passengers, and departures are usually grouped into morning waves rather than running on a strict timetable throughout the day; most operators push the bulk of departures before mid-morning so that boats are not crossing open water as afternoon winds and swell pick up. A return boat is typically arranged for the same day or the following day depending on whether you are day-tripping or staying overnight, so confirm the return schedule when you buy the outbound ticket rather than assuming you can simply flag down any boat going back.

Kali Adem (Muara Angke): The Budget Ferry Option

Kali Adem, inside the Muara Angke area, is the departure point for traditional wooden ferries, known locally as kapal kayu. Fares are noticeably lower, typically Rp75,000–95,000 one-way, but the trade-off is time: these boats are slower, less frequent, and the terminal area itself is a working fishing port rather than a polished marina, so arrive with realistic expectations about comfort and signage. This option suits budget travelers and those who are not in a hurry more than it suits a tight weekend itinerary.

The savings compared with a Marina Ancol speedboat are real, often less than half the fare, but the time cost is significant: where a speedboat might reach a mid-distance island in well under an hour, a traditional ferry covering the same route can take two to three times as long, partly because of slower cruising speed and partly because these boats more often call at more than one island en route. If your itinerary has any time pressure at all, such as a flight later that day or a tightly booked resort check-in window, the speedboat option from Marina Ancol removes a meaningful amount of risk.

Sunda Kelapa and the Banten Departure Points

Sunda Kelapa, Jakarta’s historic old port, also serves some boats toward the islands, generally grouped with the Kali Adem-style traditional ferry options rather than the faster Marina Ancol speedboats. West of the city, small informal boats from Cituis, Rawa Saban and Tanjung Pasir in Banten reach only the islands closest to that shoreline, and are a practical option mainly if you are already traveling from that direction rather than from central Jakarta. For most visitors staying in the city center, Marina Ancol or Kali Adem remain the simpler choices; see this independent guide for more on how travelers typically combine these options.

Sunda Kelapa itself is also worth knowing about even if you do not end up departing from there, since it is a working historic harbor still used by traditional Bugis schooners (pinisi), and some visitors build in an hour to walk the docks before or after their island trip, treating it as a sightseeing stop rather than purely a transport node.

Comparing Your Options

The right choice usually comes down to a simple trade-off between time and money: speedboats from Marina Ancol cost more but save hours, while the traditional ferry from Kali Adem costs less but takes most of a morning on its own. The table below summarizes the main routes.

Booking Tips and What to Bring

On weekdays outside the dry-season peak, same-day tickets are often available directly at the harbor counter. On weekends, Indonesian public holidays and during the busier dry-season months, booking a day or two ahead through an operator or local tour agent reduces the risk of turning up to a sold-out departure, especially for the farther resort islands where boats run less frequently. Bring cash in smaller denominations, since harbor-side counters do not always handle cards smoothly, and keep valuables in a dry bag: open speedboats catch spray even on a calm day, and the wet-season crossings can be genuinely rough.

Many resort islands and tour operators also sell combined packages that bundle the boat fare with accommodation, meals and a few activities, and for a first visit this is often the simplest option, since it removes the need to separately coordinate harbor transport, timing and a return crossing. If you book independently instead, double-check whether your fare includes the marine park entry fee collected on arrival at park-managed islands, since some operators fold it into the ticket price and others collect it separately at the island.

Getting to the Harbor Itself

Marina Ancol and Kali Adem are both reachable from central Jakarta by private car, taxi or ride-hailing app, with journey times that depend heavily on the city’s traffic rather than distance; budget extra time if you are travelling during rush hour. Public buses and motorcycle taxis (ojek) also reach both areas and are considerably cheaper, if less convenient with luggage. Whichever harbor you use, arriving at least 30–45 minutes before a scheduled speedboat departure is a reasonable buffer, since informal queuing and last-minute manifest checks are common. Once you have picked a route, pair it with a destination overview to choose an island and a seasonal guide to pick your dates.

If you are traveling as a family or larger group, ask whether a private charter works out cheaper per person than individual speedboat tickets once you are above roughly six to eight travelers; operators at Marina Ancol routinely quote both options, and a charter also gives you control over departure timing rather than slotting into a shared boat’s fixed schedule.
