Combu Island: Belém's 15-Minute Amazon Escape

A motorized boat leaves the Ruy Barata terminal at Praça Princesa Isabel roughly every 20 minutes, and about 15 minutes later you step onto a wooden pier on Combu Island. The crossing costs around R$20 round trip (pay at the terminal counter, cards accepted), with an extra R$5 in cash if you want the boat to drop you at a specific restaurant or trailhead along the igarapés. Few capital cities on earth put you inside a protected Amazon forest this quickly.

Combu is the fourth-largest of the 39 islands in Belém's insular region and has been an Environmental Protection Area since 1997. Around 3,000 people live here in riverside communities, many of them growing açaí and cacao in family plots behind their stilt houses. The island is not a theme park — it is a working ribeirinho neighborhood that happens to welcome visitors.

Getting There and Getting Around

The crossing from Belém

All regular passenger boats depart from Terminal Hidroviário Ruy Barata on Praça Princesa Isabel in the Condor district, along Avenida Alcindo Cacela. The terminal operates daily from 9:00 to 19:00. Boats carry around 20 to 32 passengers, life jackets are handed out before departure, and the ride takes 10 to 20 minutes depending on which pier you are headed for and how many stops the boat makes.

You need to know your destination before boarding, because the boat drops passengers at different landings rather than a single central dock. Tell the crew the name of your restaurant or pousada. If you are unsure, the most reliable approach is to name a well-known riverside restaurant and walk from there.

On the island

There are no cars. Movement happens on foot along raised wooden walkways and dirt paths, or by small boat along the Furo São Benedito and the narrower streams. Local boatmen charge about R$5 per hop between points on the island — bring small bills, since card readers are rare away from the main restaurants.

Shoes with grip matter more than you would expect. The walkways turn slick after rain, and the afternoon showers arrive with little warning between December and May.

What to Do on Combu

Chocolate, açaí and riverside kitchens

Combu's reputation rests on two crops. Cacao grows in the shade behind the houses, and several families roast, grind and mold it by hand. Casa do Chocolate da Dona Nena is the best-known producer and the standard stop on almost every tour; you can watch the beans being processed and taste the finished bars. Small chocolate houses run by other families along the main walkway are quieter and often just as good.

Açaí here is not the sweetened purple bowl sold abroad. It is served thick, cold and unsweetened, alongside fried fish, shrimp or the Amazonian catfish known as filhote. Eating at a stilt restaurant over the water is the central Combu experience — tables hang above the river, and the kitchen staff will usually let you swim off the deck between courses.

Trails, streams and the Prainha

Short forest trails cut through the protected area, passing samaúma trees with buttressed roots taller than a person. A guide is worth the fee; the trails are unmarked in places and the forest looks uniform to an untrained eye.

The Prainha do Combu, a freshwater beach on the Furo São Benedito at the back of the island, draws hundreds of bathers on sunny weekends. The currents there are genuinely dangerous — this is a river, not a lake, and there have been drownings. Families with children should stay in the shallow water near the food stalls.

Community-based visits

The Rota Combú initiative links visitors with families offering herb baths, biojewelry workshops made from seeds and fibers, and guided cacao harvesting. These are booked ahead rather than arranged on arrival, and they distribute income beyond the handful of large restaurants.

When to Go and How Long to Stay

Temperatures sit between 24°C and 32°C year-round, so there is no cool season. The rainy months run from December to May, with heavier downpours and higher river levels that can flood trails and change which streams are navigable. June through November is drier and the more comfortable window for walking.

Tides matter more than most visitors expect. The water level in the igarapés can shift several meters within a day, which affects access to floating restaurants and whether small boats can reach certain landings. If you are booking a boat tour through the narrow waterways, ask the operator to plan around the tide table.

A day trip covers the chocolate house, one restaurant meal and a short walk — roughly five to seven hours including the crossing. Staying one or two nights in a riverside chalet changes the experience entirely: the day-trippers leave by late afternoon, and the island goes quiet except for insects and passing boats.

Frequently Asked Questions

How much does the boat to Combu Island cost?

Expect about R$20 round trip from Praça Princesa Isabel, paid at the terminal ticket counter, which accepts cards. Add R$5 in cash per local boat hop if you move between landings on the island. Fees are subject to change — check the terminal for current rates.

Do I need to book a tour, or can I go independently?

Independent travel is straightforward: buy a ticket, name your restaurant to the crew, and walk the island on your own. Organized tours (roughly US$110 for a four-hour guided boat trip with hotel pickup and chocolate tasting) make sense if you want the narrow streams explained and do not want to negotiate boat hops yourself.

Can you swim at Combu Island?

Yes, many restaurants allow swimming off their decks, and the Prainha do Combu is a popular freshwater beach. Currents in the river channels are strong, so keep to shallow water near the shore and watch children closely.

Is one day on Combu Island enough?

A day trip of five to seven hours covers the chocolate house, a riverside lunch and a forest walk. Overnighting in a chalet is the better choice if you want the trails and community workshops, which run on slower schedules than the ferry.

What should I bring?

Biodegradable sunscreen and natural insect repellent are the two essentials — mosquitoes are active along the shaded walkways even in the dry season. Bring cash for boat hops and small vendors, wear shoes with grip for slick boardwalks, and pack light rain protection from December to May.
