Arraial do Cabo is defined by its reef diving, with boat-access sites spread across sheltered coves, open walls, and cave systems. The mix runs from shallow beginner reefs to deeper intermediate dives at sites like Grutazul and Buraco do Mero. French Angelfish and Reef Squid are encountered across nearly every site, while three species of moray eel, the Flying Gurnard, and the Dusky Grouper give the reefs a distinct character. Conditions stay warm year-round with March standing out in local diver preference.

The Flying Gurnard is a particularly distinctive sighting, and Honeycomb Cowfish, Spotfin Burrfish, and Pufferfish round out the common cast.
A good portion of the sites are rated for beginners, including shore-entry Prainha as well as boat-access reefs such as Ilha dos Papagaios, Ilha Dois Irmãos, and Saco da Abóbora. These sites offer shallower depths and generally mild conditions. Intermediate divers will find more to explore at sites like Grutazul and Buraco do Mero, which add caves and walls to the experience.
The vast majority of sites are reached by boat, with Prainha being the notable exception as a shore-entry reef. Acqua World is the local operator listed for the area and can arrange boat departures. Boat access opens up the full range of reef, wall, and cave sites spread around the coastline.
Reefs form the backbone of diving here, but the variety extends to cave systems and walls at sites like Grutazul and Ilha Dois Irmãos. Ilha dos Papagaios adds an artificial reef structure alongside natural reef. Depths across the sites span from very shallow entry points to moderate depths suited to intermediate divers.
