Snorkeling in Puerto Rico

Coral Reefs, Mangrove Nurseries and More

Swim from shore or take a relaxing boat ride. Either way, the coral reefs of Puerto Rico and its offshore islands are easy to reach and a pleasure to explore. Turtles and rays glide through the shallows in protected bays, while marine parks immerse swimmers in clouds of colorful tropical fish. For a different take on the underwater world, snorkelers can glide through mangrove-lined channels in sand-bottom lagoons, seeking out the many juvenile fish that hide among the tangled tree roots. In addition, Puerto Rico is also the only place in the world where snorkelers can immerse in the waters of a bioluminescent bay.

Puerto Rico Information

Snorkeling in Puerto Rico Overview

The best snorkeling conditions in Puerto Rico are usually found on the island's east coast in the Fajardo region, and on nearby islands such as Vieques and Culebra, where bays and barrier reefs create calm waters. Another prime area is along the main island's southwestern coast, where mangrove lagoons and coral reefs lie close to shore.

Snorkeling in Puerto Rico Tips

Puerto Rico offers a unique adventure for snorkelers who want to see more of the underwater world, but don't have the time or inclination to become a certified diver. The system known as SNUBA provides swimmers with an airline that is tethered to a floating air tank. This allows participants to take guided underwater tours at depths of 20 feet or less without wearing heavy tanks and dive gear.

Culture and Customs

When you arrive in Puerto Rico, you are still on US soil, but also very much in the Caribbean. No passport is needed, and English and Spanish are spoken in equal measure, but the culture is a blend of island styles and Latin-American traditions. San Juan is a cosmopolitan and thoroughly modern commercial center, but also a city with a long and storied history dating back to the days of Spanish treasure galleons and the real pirates of the Caribbean. The posh resorts and trendy boutiques of the Condado District are just a short stroll away from the narrow cobblestone streets and colonial-era buildings of Old San Juan. Drive into the mountains and as four-lane highways transition into cliff-hugging single lanes you step back into an era of village life, and then into settings where nature still takes center stage. El Yunque is the only tropical rain forest in the US National Forest System, and surrounding mountains hide an eco- adventurer's dreamscape of canyons, caves and waterfalls. At Toro Verde, the mile-and-a-half-long Monster is the world's longest zip line, and the Camuy River Cave Park features the world's third longest underground river. Surfers flock to world-class breaks near the west-coast town of Rincon, paddlers explore the mangrove lagoons of Parguera, and big game fishermen depart San Juan Harbor to do battle with trophy sized blue marlin. Those who prefer luxury over adventure can relax at premier resorts, play tour-worth golf courses, indulge in five-star spa services and sample the island's vibrant culinary scene.
