Playa Brava (Cueva de Arena) is a boat cave dive in El Hierro.
Playa Brava (Cueva de Arena) is a boat-accessed cave dive in El Hierro's La Restinga area, combining a rocky reef slope with a large overhead chamber near the mooring. The site is best known for its cave-and-ledge structure rather than big coral gardens, with black coral in the deeper section and small in-cave life like shrimp and lobsters. Plan on an intermediate cave dive with reserved buoyancy, careful ascent control, and respect for the boat mooring and overhead environment.
