Rafting the Paraibuna: A Day of Wild Water and Atlantic Forest in Rio State
A full-day whitewater escape from Rio that pairs rushes and rainforest
The river greets you before the road finishes its last hairpin—an unhurried flash of white, the sound of water striking rock, and a narrow corridor of green where the Mata Atlântica presses close. By the time the inflatable raft is inflated and the guides are running through safety checks, the city feels a world away. You push off into a channel cut through ancient stones and rainforest, and the day resolves itself into paddle strokes, shouted commands, and the rush of rapids that seem to dare you to keep up.
Trail Wisdom
Secure footwear
Wear closed-toe water shoes or sturdy sandals with straps to protect feet on rocky entries and exits.
Bring a small dry bag
Keep your phone, sunscreen, and extra layers in a compact dry bag—operators sometimes provide them but don’t rely on it.
Hydrate and eat
A full day on the river requires hydration; carry an insulated bottle and eat the provided lunch for steady energy.
Listen to your guide
Guides will give paddle commands and safety briefing—follow them promptly for safe, enjoyable runs.
