    Puerto Rico may be the fourth largest island in the Caribbean, but it is certainly one of the greatest for scuba diving. Its unique location, between the semi-protected Caribbean Sea and the open Atlantic, means that divers get the best of two realms, with sheltered reefs, pelagics from the deep, sheer drop-offs and networks of caves and tunnels, all in clear, warm waters year round. Water temperatures are in the low 80s in winter; mid-80s in summer. Visibility averages 70 feet around the main island with 100 feet or more off some of the surrounding small islands.
    Diving in Puerto Rico is mainly done off the East, South and West coasts of the island. To the east, visibility frequently approaches 100 ft. Off the coast sit two small islands ripe for diving – Culebra and Vieques. The establishment of the Culebra Marine Reserve Park ensures that its dive sites are protected. Though Vieques is known for the prior U.S. Naval bombing exercises, it actually offers very healthy reefs due to the lack of visitors there in the recent past. There are also several dive sites around a series of small uninhabited islands—Palomino, Palominitos, and Cayo Diablo, where white beaches lead to shallow, prolific reefs amongst calm waters. Along with stingrays, eels, angelfish and jacks, very often divers off the east coast see dolphins, turtles, manatees, and even sometimes passing whales.
    Puerto Rico’s Wall runs parallel to the south coast, producing sites with shocking drop offs. La Parguera, on the island’s southwest edge, features at least two dozen spots for sighting stands of black coral and pelagics. Rincon is where land-based dive operators run trips westward to Desecheo Island, another area with more dive options than there are hours in the day. A trip to pristine Mona Island is a highlight of many divers who visit, but it lies 45 miles west of the island (a 6-hour boat ride) and so the visit needs to be planned in advance.

    Some interesting dives in Puerto Rico include:

    Las Cuevas – This fascinating spot located near Desecheo that looks like Dr. Seuss molded the sea floor. Arches and swim-throughs cover the landscape, producing psychedelic effects and plenty of exploration opportunities. This boat dive starts at about 35 feet, but goes no deeper than 65 feet, which insures divers will have plenty of bottom time to search for critters amongst the super healthy reefs.
    Cayo Raton – This semicircular reef off of Culebra starts flat and then plunges down to 55 feet. The sometimes strong current makes for 100+ foot visibility on a good day of diving. Larger fish are attracted to the current, but the reef boasts a healthy collection of small creatures, too, prompting many divers to note that there seems to be an unusually large amount of fish to be seen at this site.
    Fallen Rock – This advanced dive near La Parguera will take a bit of a boat ride to get to, but bring a book and some sun screen, and you’ll be glad you made the trip. Sometime over the millenea, an enormous piece of the wall broke off and tumbled down the slope, causing a v-shaped notch that now shelters an explosion of coral and sea life. The boulder that broke off now forms a pinnacle further down the slope that divers can explore in detail, with frequent seahorses, crabs and octopus sightings. This is a deep dive, with the top of the reef at 65 feet, and the bottom dropping past 100, but the unique topography makes for a dramatic dive. All the usual reef fish can be spotted here, as can pelagics like mackerels, jacks, barracuda and spotted eagle rays that patrol the blue.
    The Wall – This wall dive near La Parguera (sometimes also called Efra’s Wall) boasts multitudes of colorful coral lining the wall and adjacent canyon. This is a great site to check out the plant life, with gorgonians, whip corals, large golden zoanthids, green finger sponges, black coral and rope pore sponges growing from what seems like every surface. This dive also offers queen triggerfish, spotted eagle rays, schools of goatfish and parrotfish, as well as a hefty dose lobster action.

    Every diver has favorite things they like to see underwater.  For some its sharks, for others rays, but for many people turtles top the list of fun aquatic finds.  The Green Turtle (Chelonia Mydas) in particular has been a scuba favorite for years due to its good looks and reef-dweling nature. 

    Despite their name, Green Turtles are actually a light color all over, with the shell ranging in color from olive green to black, depending on where the turtle lives.  Green turtles are migratory animals, traveling thousands of miles each year to nest.  In fact, they only nest on the very beach they were born, so in order to lay eggs, they must return to that same beach.

    Green turtles are on the endangered species list and therefore protected in most countries around the world.  Besides humans, the tiger shark is a Green turtle’s main predator.  Adult green turtles can grow to 5 feet long and weigh over 500 pounds, so sharks tend to target younger specimens for snacks.

    So if you are determined to dive with these beauties in the wild, where can you go for a guaranteed sighting?  The range of the sea turtle extends throughout tropical and subtropical seas around the world, with two distinct populations in the Atlantic and Pacific Oceans.  Interestingly, green turtles react differently to scuba divers depending on their location.  On one side of Oahu turtles are curious and friendly, while on the opposite shore they jet the moment they see you, so two different dive sites around the same island can produce very different results.  When visiting green turtle waters, it’s important to get the input of the locals to find the best locations for healthy, long-lasting viewing.  But planning a trip to a locale with a concentration of these green jewels is the first step.

    Atlantic

    In the Caribbean, major nesting sites have been identified on Aves Island, the U.S. Virgin Islands, Puerto Rico and Tortuguero in Costa Rica. Within United States waters, minor nesting sites have been noted in the states of Georgia, North and South Carolina.  Florida attracts them in droves especially near Hutchinson Island, Indian River Lagoon, the Florida Keys, Florida Bay, Homosassa, Crystal River and Cedar Key.  In South America green turtles enjoy the waters off Surinam and French Guiana as well as around the island of Ascension.

    Pacific & the Indian Ocean

    In Mexico, green turtles are found in seagrass pastures in the Gulf of California.  They are found throughout the Hawaiian Islands, most notably in Oahu and Lanai and west in the waters of the French Frigate Shoals.  The Turtle Islands of the Philippines and the Meru Betiri National Reserve in East Java, Indonesia boast healthy populations.  Green turtles are scattered throughout the Great Barrier Reef, but exist in high concentrations around Raine Island.  The waters around Madagascar support Africa’s population of green turtles.  The Arabian Sea also attracts the turtles, especially in Ash Sharqiyah, Oman and Karachi, Pakistan.  In the same area, the waters surrounding Astola Island, a large nesting site, have plenty of green turtles to fill your bottom time.
