Puerto Rico
Overview
Puerto Rico offers extraordinary diving variety for a single island. From the remote walls of Mona Island — often called the "Galápagos of the Caribbean" — to the bioluminescent bays of Vieques and the wall diving of La Parguera, Puerto Rico rewards divers willing to explore beyond the main tourist areas.
Mona Island, a nature reserve 70 kilometres west of the mainland, is Puerto Rico's premier dive destination. Accessible only by boat, it offers pristine walls, caves, and reefs with exceptional visibility and large marine life including manatees, hawksbill turtles, and sharks. Day trips and overnight camping are available with permits.
La Parguera on the south coast is the most developed dive area, with a wall system beginning at 15 metres and dropping to over 100 metres. The area also features the famous Phosphorescent Bay — one of the world's brightest bioluminescent bays — where millions of dinoflagellates light up the water at night.

Top Dive Sites
Mona Island — Black Wall
Mona Island's most dramatic wall dive. Black coral trees, enormous sponges, and exceptional visibility characterise this remote, pristine site. Sharks and manatees are regularly encountered.
La Parguera Wall
The main wall system off La Parguera on the south coast. Multiple entry points along the wall offer diving from beginner-friendly shallows to advanced deep sections.
Desecheo Island
A small uninhabited island off the west coast with exceptional diving. The reefs are pristine and the fish life abundant, with regular shark and ray sightings.
Mosquito Bay Night Dive
The world's brightest bioluminescent bay on Vieques. Night dives here are surreal — every movement creates trails of blue-green light from millions of dinoflagellates.
Caja de Muertos
A protected island nature reserve off Ponce with excellent reef diving. Good coral coverage, abundant fish, and regular turtle sightings in a pristine environment.
Culebra — Flamenco Wall
Wall diving off the island of Culebra, east of the mainland. Excellent coral health, good visibility, and a relaxed atmosphere make this a favourite with local divers.
What You'll Encounter
Dive Safety Reminder
Mona Island requires a permit from the Puerto Rico Department of Natural Resources — plan well in advance. The bioluminescent bay night dive at Mosquito Bay requires a licensed operator. Desecheo Island is a US Fish & Wildlife refuge; diving requires a permit and is only accessible by boat.
