Most travelers visiting Belém stick to the historic downtown core—wandering the aromatic stalls of Ver-o-Peso market or sampling craft beer at the waterfront warehouses. But Belém is surrounded by 39 river islands, and the true rhythm of Amazonian life unfolds on the water. Just across the river, wooden boats, open-air stilt restaurants, and freshwater beaches offer remarkable day trips that cost only a few dollars to reach.
Whether you have a spare afternoon or a full weekend, four specific river escapes stand out: Ilha do Combu (a 15-minute foodie haven), Ilha de Cotijuba (a car-free island of ruins and quiet beaches), Ilha de Mosqueiro (famous for freshwater surfing waves), and scenic Guajará Bay boat cruises departing directly from the city docks. Here is the practical guide to navigating each escape independently, safely, and affordably.
Why Belém’s River Islands Are the Real Amazon Gateway
Belém sits at the meeting point of the Guamá River and Guajará Bay, where massive freshwater currents flow toward the Atlantic Ocean. For centuries, the local ribeirinho (river-dwelling) communities have lived in harmony with these waterways, building stilt houses (palafitas), harvesting wild açaí, and traveling exclusively by wooden riverboats known locally as popopôs.
Stepping onto one of these boats does not require booking an expensive tour agency package. Local boat cooperatives operate regular, inexpensive passenger shuttles throughout daylight hours, allowing you to experience the Amazon rainforest’s river culture with complete independence.
1. Ilha do Combu: Stilt Restaurants, Wild Cocoa, and Açaí Groves
If you only have half a day, Ilha do Combu is the easiest and most rewarding island trip from Belém. Situated directly across the Guamá River, this environmental protection area is famous for its vibrant stilt restaurants and native açaí palm forests.
To get there, take a quick taxi or rideshare to Terminal Fluvial Praça Princesa Isabel (also known as Terminal Ruy Barata) in the Condor neighborhood. Small wooden passenger boats run continuously from morning until late afternoon. A one-way crossing takes just 10 to 15 minutes and costs approximately R$ 10 to R$ 12 (around $2.00 to $2.50 USD) per person.
When you board the boat, tell the boatman the specific restaurant or destination you want to visit. Highlights on Combu include:
- Filhos do Combu (Dona Nena): A globally celebrated artisan cocoa workshop where Dona Nena produces 100% pure bean-to-bar Amazonian chocolate. You can tour the cacao trees, sample rustic chocolate bars, and sip iced cacao juice on a wooden deck.
- Saldosa Maloca & Chalé da Ilha: Established stilt restaurants serving whole grilled Amazonian fish (such as tambaqui and filhote) paired with fresh açaí, complete with swimming decks over the river. Check our complete guide on where to eat in Belém for more traditional dishes.
2. Ilha de Cotijuba: Car-Free Trails, 1930s Ruins, and Deserted River Beaches
For travelers seeking a rustic, off-the-beaten-path day in nature, Ilha de Cotijuba offers a completely car-free escape. Private automobiles are prohibited on the island to protect its delicate flora and coastline.
Reaching Cotijuba requires two simple steps. First, take a taxi or bus roughly 20 km north of downtown Belém to the Trapiche de Icoaraci (about 45 minutes). From the Icoaraci pier, municipal ferries and cooperative speedboats (lanchas) depart regularly for Cotijuba, taking between 20 and 45 minutes and costing around R$ 4 to R$ 10 ($1 to $2 USD).
Upon disembarking at Cotijuba’s pier, you will find its iconic local transport: motorretes (motorcycles customized with wooden passenger carriages) and tractor-pulled shuttles. Key sights on the island include:
- Ruins of the Educandário Nogueira de Faria: Located right near the arrival pier, these overgrown 1930s architectural ruins once served as a juvenile correctional facility and now offer atmospheric photography among strangler figs and jungle roots.
- Praia do Vai-Quem-Quer: Situated about 9 km from the port at the far tip of the island, this secluded freshwater beach features soft sand, breezy thatched-roof food stalls, and calm, uncrowded river swimming. Arrange your return motorrete ride with the driver when they drop you off.
3. Ilha de Mosqueiro: Freshwater Surfing and Historic Tapioca Kiosks
Located approximately 70 km north of central Belém on the vast Marajó Bay, Ilha de Mosqueiro is unique: it is a massive river island featuring wide sandy beaches with real, ocean-style surfable waves. Because of the enormous volume of the Amazon estuary and strong tidal currents, Mosqueiro creates a rare natural phenomenon known as a freshwater sea (mar doce).
Unlike Combu or Cotijuba, Mosqueiro is connected to the mainland by the Sebastião Oliveira highway bridge. You can reach the island in about 1 hour and 20 minutes by rental car, private taxi, or direct intermunicipal bus from Belém’s Terminal Rodoviário in São Brás (costing under R$ 10).
Top highlights across Mosqueiro’s 20-plus beaches include:
- Praia do Farol & Praia do Murubira: The island’s most popular beaches, lined with leafy trees, beachside kiosks, and historic 19th-century rubber-boom chalets built by wealthy rubber barons.
- Tapiocaria da Vila: A celebrated culinary plaza in the town center where local tapioqueiras prepare hundreds of variations of freshly griddled tapioca stuffed with regional castanha-do-Pará (Brazil nuts), melted Marajó buffalo cheese, and shredded dried meat.
4. Guajará Bay Sunset Cruises and Dawn Wildlife Excursions
If you prefer a river excursion without traveling to the outer islands, several boat tours depart directly from the historic waterfront docks at Estação das Docas in central Belém.
The most iconic option is the daily Passeio Fluvial ao Entardecer (Sunset River Cruise), typically departing at 17:30. The 1.5- to 2-hour journey cruises past the 17th-century Forte do Presépio, the colorful skyline of Ver-o-Peso, and into the calm expanse of Guajará Bay, complete with live traditional Carimbó dance and folk music on deck (tickets cost around R$ 70 to R$ 90).
For birdwatchers and nature enthusiasts, early-morning boat tours head into the Furo da Paciência toward Ilha dos Papagaios at dawn (around 05:30) to witness thousands of wild green parrots and parakeets taking flight as the sun rises over the rainforest canopy.

Essential Island Travel Toolkit: Cash, Schedules, and Safety Tips
Exploring Belém’s river islands is safe and straightforward, but keeping a few practical logistics in mind will ensure a smooth trip:
- Always Carry Physical Cash: While some established stilt restaurants on Combu have card machines, cellular data signals frequently drop across river channels and rural beaches. Small Brazilian Real notes (R$ 10, R$ 20, R$ 50) are essential for boat fares, motorrete shuttles, and beach snacks.
- Confirm the Last Return Boat: Before leaving the pier or sitting down for lunch, always ask your boatman or motorrete driver when the final return trip departs (usually between 17:00 and 18:00 before sunset).
- Sun and Insect Protection: The equatorial sun is intense on open water, and river edges are home to midges and mosquitoes. Bring high-SPF sunscreen, polarized sunglasses, a hat, and biodegradable insect repellent.
- Useful Portuguese Phrases: When arriving at Praça Princesa Isabel, simply say “Vou para o restaurante [Name]” (I am going to [Name] restaurant) to be directed to the correct boarding boat.
