Nature and Outdoor Activities in Brazil in 2026: The Best Ways to Explore

Brazil's outdoor geography covers 8.5 million square kilometres of biome diversity. The Amazon Basin — 60% of Brazil's territory — is the world's largest tropical rainforest; river boat journeys into the flooded várzea forest during high water season, when the trees are submerged to the canopy and river dolphins swim between trunks, represent an outdoor experience with no equivalent. The Pantanal — the world's largest tropical wetland — is the best place on earth to see jaguars in the wild, with cat density and open habitat combining for daytime sightings that are becoming routine. The Chapada Diamantina highlands in Bahia carry cave systems, tabletop mountain hiking, and the Fumaça waterfall (340 metres, the highest in Brazil) above a landscape of crystalline rivers. The lençóis maranhenses coastal dunes — freshwater lagoons inside enormous white dunes — exist only for a few months after the rains. Then the hidden gems start showing up. No rush.
