Fernando de Noronha is one of the best diving areas in Brazil. Its clear waters with an optimum temperature of 28-30 Celcius ( 73 - 86 Fahrenheit) and visibility of around 30 m ( 98 ft) allow for viewing the varied and sometimes endemic marine life in over 20 dive sites around the island, including:
Pedras Secas (17m - 56 ft), regarded as one of the top 10 dive sites in the world has an impressive rocky formation of tunnels, caverns and canyons, covered with corals and sponges. Squirrelfish, black margates, grunts, sea turtles and sand sharks frequent this spot.
Buraco das Cabras (16 m - 52 ft) is one of the most vibrant diving areas, with a plethora of colors emerging from the rock formations, and huge variety of marine and plant life seen here such as manta rays, barracuda, turtles, angelfish, octopi, hammerhead sharks, lobsters, blackjacks, corals and sponges.
Morro de Fora (15 m - 49 ft) is a nursery site with several infant species, including flounders and queen angel fish. This and Cagarras Rasas (16 m - 52 ft) where fire coral and a huge number of beautiful ornamental fish can be viewed, such as surgeons and damselfish, are good spots for beginner divers.

Cabeco Submarino (20 m - 66 ft) is probably the best dive area for turtle lovers.
Cabeco da Sapata (43 m - 141 ft), an excellent multi level dive site, only suitable for advanced divers, due to the depth and strong currents, is a small submarine mountain that rises nearly above the water level. Here triggerfish, grunts, chromis and horse-eyed jacks can be found.
