Isla De San Francisquito - Sea of Cortez
Isla De San Francisquito gives you a classic Sea of Cortez rocky reef dive. Expect to cruise along walls and boulder fields, keeping an eye out for moray eels tucked into crevices and parrotfish grazing the algae. It’s a solid spot for divers who appreciate the subtler beauty of the region, perhaps as a mellow second dive. Good for photographers focusing on macro subjects.
