Culebra diving and snorkeling

A small island built for the water

Culebra is an island municipality of Puerto Rico, about 17 miles east of the main island, part of the group often called the Spanish Virgin Islands. It is small, hilly and unhurried, with one town, Dewey, and a handful of beaches that regularly appear on lists of the Caribbean’s best, Flamenco Beach above all. For divers and snorkelers, the attraction is the water: Culebra sits on a shallow bank, and much of its coastline and the cays around it are fringed with reef.

Large parts of the island and most of its offshore cays belong to the Culebra National Wildlife Refuge, one of the oldest wildlife refuges in the United States system, and an important seabird nesting area. Its beaches are nesting sites for sea turtles, including leatherbacks.

The Luis Peña Channel reserve

Between Culebra and Cayo Luis Peña, just to the west, lies the Luis Peña Channel Natural Reserve, a no-take marine reserve. Fishing and collecting are not allowed, and the reefs, seagrass and fish life show the difference. Beaches on this side of the island, such as Tamarindo and Melones, are popular for shore snorkeling, and the seagrass beds are a reliable place to watch green sea turtles feeding.

Diving around the cays

Boat dives visit the reefs around the cays that surround Culebra, including Cayo Luis Peña to the west and Cayo Lobo to the east. Expect coral heads, ledges, small walls and boulders covered with sponges and sea fans, with reef fish, lobster, rays and turtles. Most sites are moderate in depth, which makes Culebra a comfortable place for newer divers, refresher dives and courses, while the outer cays give more experienced divers plenty to explore.

Snorkelers do especially well here. Carlos Rosario Beach, reached by a short walk from Flamenco, has a reef close to shore, and many dive boats welcome snorkeling companions.

Getting to Culebra

Passenger and cargo ferries to Culebra leave from the ferry terminal in Ceiba, on Puerto Rico’s east coast, about an hour’s drive from San Juan. Ferries can sell out on weekends and holidays, so buy tickets ahead and arrive early. Small planes also fly to Culebra from San Juan and Ceiba, which is quicker and avoids the ferry queue. Some Fajardo-area dive boats run trips to the reefs between the mainland and Culebra as well.

On the island, golf carts and jeeps are the usual way to get around, and they also need booking ahead at busy times. Read the Puerto Rico dive travel guide for more on ferries, flights and timing.

Beyond the reef

Culebra is an easy island to slow down on. Between dives, spend an afternoon at Flamenco Beach, hike to a quiet bay or take a kayak out along the coast. The island has a handful of restaurants and small grocery stores, mostly around Dewey, and many close early or on certain days of the week, so check hours and plan meals ahead, especially outside the winter season.

Planning a Culebra dive trip

• Book dives before you arrive. Culebra has only a few operators, and boats are small.
• Bring cash as well as cards. Services are limited on a small island.
• Plan your last dive at least 12 to 18 hours before a flight (see the flying after diving guidance), including the small planes.
• Respect the reserve: no fishing, collecting or touching, and keep fins off the bottom.

Culebra pairs well with its neighbor Vieques, and with a few days on the main island. Compare them with the other regions on the Puerto Rico dive sites page.
