Gruta do Mimoso is not a sightseeing visit. It is a descent. A 300 meter trail leads to the cave entrance and, from there, a staircase takes visitors underground toward the partially flooded chamber where the snorkeling float takes place. Interior lighting comes from the natural light entering through the cave opening, from an artificial light installed inside the cave, and from the flashlights handed out at the entrance, one for every two visitors.
In this underground setting, participants float over the cave waters while observing the rock formations around them. The tour lasts 1h30min, and all equipment is provided.

Gruta do Mimoso is a cave with a partially submerged inner chamber. The difference from other cave tours in Bonito lies in the type of access: here, visitors do not observe from above, from a deck, or from a walkway. The participant goes down and enters the water.
The cave interior receives natural light through the entrance opening and also has an artificial light installed inside. For the snorkeling float, every two visitors receive one flashlight. This lighting setup, different from scenic environments with elaborate illumination, is what makes the experience distinct: visitors explore the cave with the light they carry, in underground silence.

Upon arrival, participants go through a full introduction with the guide before entering the cave.
Participants receive all equipment on-site: wetsuit, life jacket, snorkel, and water shoes. Next, the guide presents instructions about the activity, the equipment, and the safety procedures. Visitors must arrive 30 minutes in advance, because the tour is exclusive to the time scheduled on the voucher.
A 300 meter trail leads to the cave entrance. There, the access staircase takes participants down to water level. The starting point of the snorkeling float varies depending on the time of year: visitors report that, during periods of heavier rain, the water level rises and entry into the water happens earlier on the staircase.
The snorkeling float follows the cave interior with guide assistance throughout the route. At the end of the activity, participants go back up the staircase and have access to changing rooms, showers, and storage lockers in the support area.

Gruta do Mimoso is recommended for children aged 8 and up when accompanied, adults, and groups that want to combine physical activity with the exploration of an underground environment. No previous experience is required, and the effort level is moderate.
For groups with children under 8, we do not recommend this tour: the access staircase and the dark environment require maturity and cooperation to ensure a safe experience for the whole group.
It is not possible to use bug spray or sunscreen before the activity. Anyone arriving from another tour after applying these products must inform the guide upon arrival. Pregnant guests may participate up to 24 weeks of pregnancy. Any relevant health condition must be reported to the team before the start: diabetes, hypoglycemia, high or low blood pressure, severe allergies, respiratory, heart, and blood conditions.
With 35 years of experience in Bonito, Bonitour provides guide assistance throughout the activity and accident insurance included in the tour price.

"Access is via a wide, easy staircase with 61 steps. Depending on the season, the water level rises and people reach the water after going down fewer steps. It is worth it for the striking beauty of the cave and the water."
— EDISON PS
"Honestly, we did not expect the cave to be so impressive. As soon as we entered, we felt transported to an underground world, silent, just us and nature. The environment is dark, and the only lighting comes from the flashlights provided at the entrance, which makes the experience even more immersive."
— Isaias Borges
"It is a unique experience. I had never floated inside a cave, so I was scared, but like all tours in Bonito, it had great structure and was very organized. I recommend splitting the photo package cost with your group, because it is very dark there and our own photos did not turn out that well."
— Debora Bastos
