About Bonito

Bonito's rivers are so clear that snorkellers float among fish in the Rio da Prata and Sucuri, and the region's sinkholes and caves add diving. The surroundings sit on the edge of the Pantanal, and waterfalls, macaw feeding grounds and forest trails fill the days. May to September is the dry season with the clearest water; the rainy months are greener, and most tours need advance booking.
