Carabinero Wall, also called the East Walls, is a boat-dive wall at Isla de Mona that starts in about 20 feet and continues to roughly 500 feet, far beyond recreational limits. Depth and current are the main hazards, so plan your depth carefully. A 1998 guide gave a diving range of 30 to 130 feet. It lies within Isla de Mona Natural Reserve; check current DRNA rules.^[1]^[2]^[3]
