Dive-site story
Situated along the exposed southeastern perimeter of Fernando de Noronha, Trinta Réis sits beneath a rugged volcanic rock formation frequented by nesting sea birds. Underwater, dramatic basalt boulders, crevices, and ledges drop onto a sandy seabed. Currents frequently draw pelagic species in from open water, while the rocky structure provides refuge for resting nurse sharks and stingrays.
Rugged volcanic topography featuring rock crevices, overhangs, and swim-throughs
Frequent encounters with resting nurse sharks and southern stingrays
Pelagic action including schools of jacks, barracudas, and cruising reef sharks
Location
Use the map to plan with your operator and confirm the exact entry point on the day.
Seasonality
The Mar de Fora coast tends to offer calmer sea conditions and optimal boat access when southeasterly winds diminish in the later half of the year.
