Gruta Azul

Three exits that turn a stone cave into a circuit

Gruta Azul is one of the more interesting cave dives on Santa Maria: a shallow system of stone corridors with several ways in and out. Its connected passages pass through a wide variety of settings without ever going deep.

The dive

The cave never goes below 17 m. Its 150 m of stone corridors connect to three different exits, so a dive can run as a circuit through the cave rather than in and back out by the same way, passing a wide variety of settings in the rock.
