Boat-access volcanic arch and wall dive with gentle drift profile.
Boat-access volcanic arch and wall dive with gentle drift profile.
Arco do Cavaco is a boat dive along São Miguel's volcanic coastline, where arches, fingers of rock, and wall-like relief create an interesting drift-style route. The site suits divers who enjoy moving water and coastal structure more than a single fixed attraction, with the shape of the terrain changing as the line follows the rock.

Scuba Diving
Good for drift dives with a maximum depth around 25 m.
Freediving

Snorkeling
Arco do Cavaco is not a practical snorkel site because the boat access and drift-style route are designed for scuba divers.
