Morning light slides between the Serra do Mar ridges as a minibus hums toward Três Rios, the river valley opening like a painted map. The guide’s voice is practical and steady: safety briefing, paddle commands, weight distribution. Then the raft meets current and the countryside takes over — fast water cutting through forested banks, granite outcrops nudging channels, and occasional calm pools that let the river breathe.

Morning light slides between the Serra do Mar ridges as a minibus hums toward Três Rios, the river valley opening like a painted map. The guide’s voice is practical and steady: safety briefing, paddle commands, weight distribution. Then the raft meets current and the countryside takes over — fast water cutting through forested banks, granite outcrops nudging channels, and occasional calm pools that let the river breathe.
The circuit runs about 12 km (7.5 miles) and lasts roughly three hours on the water, but the full day includes transport from Rio (about 2 hours each way) and a riverside lunch. Geologically the area sits on the foothills of the Serra do Mar where tributaries converge; culturally the valley blends farming communities and a long tradition of river recreation — this is the only place in Latin America where the Paraibuna, Paraíba do Sul and Piabanha rivers meet to form a rare triple delta.
Expect rapids from class I to class III depending on season (drier months are milder). Instructors are certified by the International Rafting Federation and provide full rafting gear. Practical prep pays: wear water shoes, a swim suit under quick-dry layers, bring sunscreen, insect repellent and a change of clothes. Travelers with heart or spinal issues should avoid participation; moderate fitness and basic swimming comfort are required.
Timing matters — higher flows (Oct–Apr) make the run more intense; May–Sep is mellower. The trip finishes with a homemade Brazilian lunch and a short rinse before the return drive. It’s a full, well-guided day on one of Rio’s most scenic rivers, equal parts adrenaline and countryside immersion.
Expect roughly three hours on the water covering about 12 km; the full excursion including transport and lunch makes for an 8–10 hour day.
Yes — instructors are certified by the International Rafting Federation and full rafting equipment is supplied.
