You'll find a sandy bottom with scattered rocky outcrops, home to crabs, wrasse, and sometimes conger eels tucked into crevices. It’s a good spot for newer divers getting comfortable with entries and exits, or for photographers looking for macro subjects without strong currents. We've found the visibility can be variable, but on a good day, it’s a pleasant, easy dive.
