The tour begins with a short interpretive trail through the forest that surrounds the doline, an opportunity to observe the rich diversity of fauna and flora.

The trail leads to the observatory, where you can admire the beauty of trees that covers the 75 meters deep doline, and see the Mysterious Lagoon at its bottom.

The access to this lake of blue waters is made by a staircase of 179 steps, comfortable and safe. Groups are limited to 10 visitors, always accompanied by a local guide.

Arriving on the access deck to the Mysterious Lagoon, the visitor receives the equipment that will be used for the snorkeling: mask, snorkel and life jacket. For those who choose not to snorkel, you can admire the blue waters of the lagoon.

The snorkeling is indescribable: be amazed by contemplating the vastness of the Mysterious Lagoon, the vision of the two blue abyss on the bottom, the fallen tree trunks, the deposits of white sand, the small fish that glow with the light beams. 

The snorkeling  is carried out in a circular loop in the Mysterious Lagoon.

Total duration of the tour: about 1h40min

Because of the proximity of the attractions you can do the trail and snorkeling tour in Recanto Ecológico Rio da Prata on the same day of the Mysterious Lagoon tour.
