Community notes to help plan your visit.
Scuba Diving
Scuba is the primary fit here. The dive stays close to the rock structure, with the main attraction in the fish and megafauna traffic.
Freediving
Not a freedive-first site; the main structures sit at scuba depths and are better handled from a boat.
Snorkeling
Tres Rocas is mainly a scuba stop; snorkel time is usually better handled elsewhere on the broader Isla de la Plata day trip.
