Ilha Rasa - Portinho is a sheltered boat dive on the leeward side of Ilha Rasa in Rio de Janeiro, with a rocky coastline that eases toward sand and a deeper outer profile offshore. It is widely used as a beginner-friendly alternative when southwest swell is up, but planning still needs attention to sea state, boat timing, and the shallower inshore-to-deeper transition.

Community notes to help plan your visit.
Scuba Diving
Classic sheltered Rio boat dive for refresher dives, beginner sessions, and deeper profiles offshore.
Freediving
Possible in calm conditions, but the site is primarily a scuba boat dive rather than a freedive destination.
Snorkeling
Snorkeling is secondary here; the sheltered edge is only worth it when sea state is calm and supervision is tight.
