Shared or private: when does the math work out?
Dividing the boat's price by the number of people, the gap narrows as the group grows:
- The 3 Islands with 14 people: R$ 2,850 split comes to about R$ 204 per person, close to the R$ 200 charged on the shared tour.
- The 3 Islands with 10 people: R$ 2,200 split comes to R$ 220 per person.
- Montão with 10 people: R$ 3,000 split comes to R$ 300 per person, against R$ 250 on the shared tour.
For couples and small groups, the shared tour is usually the better deal. Large groups pay only a little more for exclusivity and get to choose their own time slot. The full breakdown is in shared or private: how to choose, and the most requested private route is in private boat tour of the 3 Islands of the South Coast.

How does payment and cancellation work?
Under the agency's terms of use, shared tours require 100% payment in advance. Private tours require a 50% deposit at booking and the rest at boarding. The cancellation policy provides for:
- An online purchase canceled up to 7 days before the tour date: full refund.
- Outside that window: 100% up to 72 hours before, 50% up to 24 hours before, and nothing for cancellations less than 24 hours out or no-shows.
- Cancellation due to weather, maritime safety or operational reasons: rescheduling at no cost or a full refund.
The price also depends on age. All tours use the same age brackets: Infant (up to 2 years), Young child (3 to 10 years), Teen (11 to 17 years), Adult (18 to 64 years) and Senior (65 years or older). The price for each bracket appears on each tour's page, and some routes don't accept every bracket. Anyone under 18 must book together with a responsible adult.
Are there any costs beyond the tour itself?
Yes: getting to the departure point, since Uber and 99 don't operate in São Sebastião. The guide getting to Maresias and getting around helps with planning. On top of that, factor in a snack, water and, if you'd like, your own snorkel mask.
