Overview

Heads up: parts of Isla Culebrita still have unexploded ordnance, so stay on marked trails, and the refuge limits access to some areas. Beaches and trails are open 6 a.m. to 6 p.m. with no facilities, and anchoring on refuge beaches is not allowed because sea turtles nest there; check current refuge rules. Culebrita, east of Culebra in the Culebra National Wildlife Refuge, is a snorkel and shore-dive spot reached by water taxi or boat. A travel guide says snorkelers and divers can reach the reef from shore, with sea turtles, rays and reef fish; another rates South Beach and East Beach for snorkeling.[1][2][3][4][5]
