The Boca da Onça Ecotour, 59km northwest of Bonito, is a nicely manicured 4km trail through the forest to a series of 11 waterfalls, a few of which you can take a chilly dip in. It all culminates with the 156m Boca da Onça waterfall, an impressive cascading waterfall that takes the state’s highest honors. It’s an 880-step climb back to the fazenda, where there is an excellent lunch and hang time by a fantastic natural river-water pool, full of local fish.
