Calvin's Crack is one of the most popular dive sites in the east of Roatan, at the south side of Cat Island. The mooring is in 7 meters and the crack is to the west of it. The entrance is awkward but not really small. If a diver is worried they can enter further down the crack, where the tunnel widens up and is completely free of overhangs. The depth of the crack goes from 9m to almost 30. You can exit the crack at 19m and 25m but you must be careful not to harm the wire coral. You need good buoyancy control in order not to break the coral.
