Bonito takes its name literally — this small town in Mato Grosso do Sul sits beside some of the clearest freshwater rivers on the planet, where snorkelling feels like floating through a giant aquarium amid shoals of dourado and piraputanga. Visits are tightly regulated, with most attractions bookable only through licensed agencies and limited daily visitor numbers, which keeps the rivers, caves and waterfalls remarkably pristine.

Traveler reviews
★★★★★
The Rio da Prata snorkel was unbelievable — water so clear it felt like swimming in glass, with huge fish swimming right alongside us.
Camila R. · July 2023
★★★★★
Everything has to be booked through agencies which felt restrictive at first but it's clearly why the rivers stay so pristine.
Jonas W. · August 2024
★★★★☆
The Blue Lake cave was stunning, just bring a jacket as it's noticeably cooler underground than outside.
