Banyak Islands, Aceh: How to Reach Sumatra's Quietest Island Chain on Your Own
Most people who plan a Sumatra trip land in Medan, point themselves at Lake Toba or the orangutans of Bukit Lawang, and never look west. That is a pity, because off the far southwest coast of Aceh sits an archipelago called the Banyak Islands. Banyak means "many" in Indonesian, and the name fits: the chain is usually described as roughly a hundred islands, most of them tiny, uninhabited and ringed by sand and reef.
The catch is the journey. There is no resort shuttle, no one-click booking and, for independent travelers, very little written in English that is current. This guide pulls together what travelers and local sources report about getting from Medan to Singkil, from Singkil to the islands, and what to do once you arrive. Where details are uncertain or have changed over the years, we say so. Boat times, fares and homestay rates in this part of Indonesia shift often, so treat every number below as a starting point and confirm it locally.
What the Banyak Islands actually are
The Banyak Islands belong to the Aceh Singkil regency, in the far south of Aceh province, close to the border with North Sumatra. The regency's harbor town, Singkil, is the mainland gateway. Most visitors base themselves on or near Pulau Balai, the main inhabited island and the arrival point for boats, then hop to neighboring islands by small boat.
A few names come up again and again:
- Pulau Balai is the hub. It has the harbor, the largest cluster of homestays and the few shops you will find.
- Palambak (Palambak Besar and Palambak Kecil) and Tailana are the islands most travelers rent a small boat to reach. Local guides point to snorkeling around Palambak Kecil, Tailana and Asok.
- Pulau Rangit is known for its lighthouse.
- Bangkaru is the remote outlier, usually mentioned by people who want to go further than the standard route.
If you want a rundown of the beaches themselves, our guide to the best beaches in the Banyak Islands covers them. This article is about the harder question: how you actually get there.
Step 1: Fly to Medan
Medan's Kualanamu International Airport is the practical starting point for nearly everyone, with connections from Jakarta, Kuala Lumpur and other regional hubs. Plan to spend a night in Medan so you do not start a long road journey straight off a flight.
There is a smaller airport near Singkil, Syekh Hamzah Fansyuri Airport, which sits closer to the harbor. Regional flight schedules to small Sumatran airports change a lot, and we could not confirm a reliable current timetable. If you find a flight, it will save you most of a day. If you do not, plan on the road.
Step 2: Medan to Singkil by road
The long leg is the overland trip from Medan to Singkil. Travelers report that it takes somewhere around eight to ten hours, depending on traffic, road works and how many stops you make. One recent traveler account put a private car at about 900,000 rupiah, which works out cheaper per person when you split it between three or four people. Shared minibuses and buses also run along this corridor, usually via Sidikalang or the west coast road, and cost less but take longer and rarely leave on a fixed schedule.
A few practical points:
- Start early. Leaving Medan around dawn gives you daylight for the mountain sections and a realistic chance of reaching Singkil in the afternoon.
- Sleep in Singkil, not on the road. Boats to the islands depart on the tide (more on that below), and arriving the night before removes the stress of making a morning departure.
- Carry cash. Withdraw what you need in Medan. ATMs become scarce quickly after you leave the city, and they are scarcer still on the islands.
- Pack for motion sickness. The road winds through hills for long stretches.
Step 3: Singkil to Pulau Balai by boat
From Singkil harbor, boats run to Pulau Balai. Wikivoyage notes that boats are frequent but only leave at high tide, which means your departure time depends on the tidal calendar, not a printed timetable. Ask at your Singkil guesthouse or the harbor office what time the next high tide falls, and be at the pier early.
Reported crossing times vary a lot. Some sources say around three and a half hours; a forum account describes four to five hours on a larger boat from Singkil to Balai, followed by two to three more on a speedboat if you are continuing to a farther island. The spread comes from different boats, different sea conditions and different destinations. A safe assumption is a half day on the water, with the possibility of a second, shorter leg afterward.
Sea conditions matter. Wikivoyage recommends visiting between March and August, when seas are calmer. Outside that window, crossings can be rougher and boats may not run on bad days. Build at least one spare day into your schedule so a cancelled boat does not wreck your flight home.
Step 4: Choose where to sleep
Accommodation on the Banyak Islands is simple: family-run homestays and small beach bungalows, many with fan-only rooms, shared bathrooms and electricity limited to certain hours. This is not a place to expect air conditioning or reliable Wi-Fi. What you get in exchange is a front-row seat on quiet beaches and clear water.
Tips for booking:
- Message ahead when you can. Many homestays take bookings through WhatsApp, and some will arrange your boat pickup in advance.
- Ask what meals include. Because supplies come over by boat, food is usually fresh fish, rice and vegetables, and often included in the nightly rate, which in this region is frequently quoted as a package with meals.
- Confirm the island, not just the name. Several homestays use "Banyak" in their name while sitting on different islands, and the transfer cost between them adds up.
- Ask about drinking water. Bring a refillable bottle and purification tablets or a filter bottle as a backup.
Step 5: Island-hopping and snorkeling
Once you are settled, the standard routine is to rent a small boat with a local operator for a half or full day. Local guides focus on three snorkeling areas: Asok, Tailana and Palambak Kecil. Visibility and coral condition depend on weather and season, so ask your host what the water has been like in the past few days instead of relying on photos.
What to bring and how to behave:
- Bring your own mask and snorkel if you can. Rental gear exists but quality varies.
- Wear reef-safe sun protection or a rash guard. There is little shade on the sandbars.
- Agree on the price and route before you leave. Boat rates are usually per boat, not per person, so groups save money.
- Do not touch or stand on coral, and take every piece of trash back with you. The islands have no waste collection on the smaller cays.
If you are an experienced traveler comfortable with a longer, rougher crossing, Bangkaru is worth asking about. It is remote and is known among conservation circles for sea turtle nesting, but access depends on weather and local arrangements, and we could not verify current rules for visitors. Ask your homestay or the local tourism office before planning around it.
Etiquette and local rules in Aceh
Aceh is the only Indonesian province that applies sharia-based local regulations, and that shapes daily life even in a remote island chain. For visitors this mostly means:
- Dress modestly in villages. Cover shoulders and knees when you are away from the beach. Swimwear is for the water and the sand.
- Alcohol is not sold, so do not count on a beer at sunset.
- Ask before photographing people, especially women.
- Respect prayer times. Boat operators and guides may pause for midday and evening prayers.
Locals are generally warm and curious toward the few foreigners who make it this far. A little Indonesian goes a long way, and so does patience.
A realistic itinerary
Here is a pace that works for most travelers who want to see the islands without rushing:
Day 1: Fly to Medan and rest.
Day 2: Drive Medan to Singkil and sleep near the harbor.
Day 3: Take the high-tide boat to Pulau Balai, settle in and swim.
Day 4: Rent a boat for Palambak, Tailana and Asok snorkeling.
Day 5: Free day for Rangit, a village walk or simply doing nothing.
Day 6: Boat back to Singkil, overnight there.
Day 7: Return to Medan.
Seven days sounds like a lot for three days of island time, and it is. That ratio is the honest cost of the Banyak Islands. If your time is short, the islands near Sabang in northern Aceh are far easier. See our Weh Island guide for that alternative.
What to pack
- Cash in small bills
- Reef-safe sunscreen, hat and rash guard
- Your own mask and snorkel
- Motion sickness tablets
- Dry bags for phones and passports on small boats
- A power bank, since electricity may be limited at night
- Insect repellent
- Basic medication, including rehydration salts
Is it worth the effort?
The Banyak Islands reward travelers who value quiet over comfort. The journey is long, the facilities are modest, and the timetable bends to the tide. In return you get shallow turquoise water, empty beaches and the satisfaction of reaching a corner of Sumatra that most visitors never see. Go between March and August, leave a buffer day on both ends, confirm every boat locally, and bring more cash than you think you need.
Boat schedules, fares and island rules change frequently. Before you travel, confirm current details with Singkil harbor authorities, your homestay or the Aceh Singkil tourism office.
