The largest of a series of rocky seamounts at the edge of Banderas Bay where cold Pacific water collided with warm water from the bay, El Morro is only visited by divers. Despite its underwater riches, El Morro and it’s neighbors, Los Anegados paint a fascinating portrait of life on the isolated guano rocks of the Pacific.

Frequently overshadowed by the much more famous Playa Escondida on the nearby Islas Marietas, skip the 15 minutes and torturous swim to get to this tourist trap and spend your money to dive El Morro, it is an adrenaline thrill for advanced SCUBA divers.
