The best area to stay in Boca Do Jari is along the main riverfront road, Avenida Castelo Branco.
This area is the heart of Boca Do Jari, where most of the town's limited amenities are located. Avenida Castelo Branco runs parallel to the Jari River and is where you'll find the few guesthouses, restaurants, and shops. It's the most developed part of the town, offering the most convenience and a central base for exploring the surrounding natural environment.
For nature enthusiasts and adventurers, staying along Avenida Castelo Branco is ideal. From here, you can easily arrange boat trips up the Jari River or excursions into the nearby Amazon rainforest. The proximity to the river means you're right at the doorstep of the region's main attraction, making it convenient for early morning departures or sunset returns.
Given the town's small size, staying anywhere else would mean being further away from the available services.
