A half-day boat-and-hike from Paraty into Brazil’s only tropical fjord—Saco do Mamanguá—culminates in a steep 425 m ascent to panoramic views of rainforest-clad ridges and sheltered bays. Expect a fastboat ride, a roughly 1 hour 20 minute climb, and time to swim and eat on Cruzeiro Beach.

You step off the fastboat into the narrow green mouth of Saco do Mamanguá and the fjord closes around you—steep rainforest slopes folding into the water, small wooden houses clinging to shorelines, and the Sugarloaf’s granite bulk rising ahead.

History
Saco do Mamanguá lies inside the Juatinga Ecological Reserve area and is dotted with traditional caiçara communities whose livelihoods have linked fishing and small-scale farming for generations.
Conservation
The fjord’s mangroves and coastal forest are ecologically sensitive—stick to trails, avoid single-use plastics, and support local kiosks that source seafood sustainably.

Bring 1.5 L of water

Sun is strong on exposed ridgelines and mosquitoes are common at lower elevations—use sunscreen and repellent.
