Together with an English-speaking guide, you will explore the beautiful surroundings of Bonito. Among other things, you will visit Lagoa Azul. The caves derive their name from the bright blue colour of the lagoon. You will also go snorkelling in the Rio da Prata Ecological Refuge, a natural park whose main attraction is the transparent blue water of the Olho d'Agua spring of the Rio da Prata river. This natural park attracts many snorkelling enthusiasts who enjoy the sight of fish and underwater plants in the clear lake. During this excursion, you will also put on a special wetsuit, allowing you to drift down the river in a relaxing way. The water is crystal clear, giving you the feeling of being in a natural aquarium.
