Cayos de la Cordillera Beach Nature Reserve is a protected island chain off Fajardo, Puerto Rico, celebrated for its turquoise waters, coral reefs, and undisturbed wildlife.
Cayos de la Cordillera Beach Nature Reserve encompasses a chain of small uninhabited cays managed to protect one of Puerto Rico's most biodiverse coastal zones. The reserve's reefs support elkhorn and brain coral alongside an abundance of reef fish, making it a rewarding destination for snorkeling at nearly any skill level.
Visitors arrive by boat from Fajardo, and several operators offer boat tours that stop at the reserve's sandbars and reef sites. The crossing itself offers views of the northeastern coast and, on clear days, the distant outline of the Spanish Virgin Islands. Sea turtles are frequently spotted feeding in the seagrass beds, and the birdlife along the cay edges includes pelicans and frigatebirds.
The reserve sits within a broader network of natural landmarks. Nearby, Laguna Grande is a celebrated bioluminescent bay, and the historic lighthouse at Faro Cabezas de San Juan anchors the protected headland to the north. Together these sites form one of Puerto Rico's richest coastal corridors.
Cayos de la Cordillera Beach Nature Reserve rewards visitors who come prepared to move slowly, observe carefully, and leave nothing behind. It is a place where the Caribbean still looks the way it once did across the whole region.
Visit on a weekday morning to have the sandbars and snorkeling spots largely to yourself before day-trip boats arrive.
Bring reef-safe sunscreen, as conventional sunscreen chemicals are harmful to the coral ecosystems protected within the reserve.
Wear water shoes when wading across sandbars, since sea urchins are common in the shallower reef areas.
Pack your own food and water, as there are no facilities or vendors within the reserve itself.
Book a guided boat tour from Fajardo early in your trip, since departures can fill up quickly during peak season.
