The crystalline waters of the Aquário Natural (Natural Aquarium) are the main attraction of the Bonita Bay Ecological Reserve. The diversity of the river´s fauna and flora makes the tourist feel literally within an aquarium. The ideal is to snorkel down the river, but there is also the option to accompany the group on a support boat. The pool of the main house is also used to educate visitors about the use of mask and snorkel. Besides the aquarium, the Trail of animals is another unforgettable attraction of the reserve, through which animals, like rheas, alligators, deer, wolves and anacondas, can be seen.
