Culebra is an island on a plateau between mainland Puerto Rico, St. Thomas and Vieques, with about 50 dive sites, most under 20 minutes by boat. Most dives run 9 to 24 m (30 to 80 ft), and the best known include the long sea-fan reef at Carlos Rosario, the Wit Power tug sunk in 1984 and the cup-coral arch at Cayo Yerba. The Luis Peña Channel Natural Reserve is a no-fishing area, and the Cayo Ballena wall drops to 37 m (120 ft).

About diving in Culebra

Diving here is by boat. The island shop sits in town across the street from the ferry terminal and less than 1.6 km (1 mile) from the airport, and its guides pick the day's sites each morning from a list of about 50. Rides to and between sites are usually under 20 minutes, and entry is a giant stride, with sidemount and in-water kitting handled on request. Conditions permitting, a one-tank fluoro night dive leaves just before sunset and is back at the dock by 9 pm.

The island sits on a plateau, and its sites are reefs, walls and sometimes wrecks. A shallow dive runs 9 to 14 m (30 to 45 ft) and a deep one 15 to 24 m (50 to 80 ft); Cayo Ballena is the exception, a wall to 37 m (120 ft). Visibility averages about 18 m (60 ft) and the current is generally mild. The shallow reefs have been hit hard by warmer water, while deeper coral is still thriving. Carlos Rosario carries huge sea fans, Cayo Raton is known for the number and variety of its fish, and the Luis Peña Channel reserve is closed to fishing.

Culebra suits divers of all levels: rides are short, the current is mild and most sites stay inside 18 m (60 ft). From mainland Puerto Rico, Sea Ventures runs a full-day trip, which means a crossing of nearly 32 km (20 miles) each way in variable seas. The guidance is to wait 12 to 18 hours after diving before flying, and that includes the island-hopper flights off Culebra, so the last dive day needs planning.
