Community notes to help plan your visit.
Scuba Diving
Boca da Baleia works best as a deliberate operator-led scuba route that follows the rock profile and lets the team stay close to structure if current picks up.
Freediving
Not a normal freedive stop because the route is built around offshore scuba-boat logistics and a more open, current-sensitive profile.
Snorkeling
Not a practical snorkel option for most visitors because the site is offshore and the main value is along the submerged rock profile.
