Isla Culebra (Snake Island) is an island, town and municipality of Puerto Rico and geographically part of the Spanish Virgin Islands. It is located approximately 17 miles (27 km) east of the Puerto Rican mainland, 12 miles (19 km) west of St. Thomas and 9 miles (14 km) north of Vieques. Culebra is spread over 5 barrios and Culebra Pueblo (Dewey), the main town and the administrative center of the island. Residents of the island are known as culebrenses. With a population of 1,792 as of the 2020 Census, it is Puerto Rico’s least populous municipality.
Originally called Isla del Pasaje and Isla de San Ildefonso, Culebra is also known as Isla Chiquita (“Little Island”), Cuna del Sol Borincano (“Cradle of the Puerto Rican Sun”) and Última Virgen (“Last Virgin”, due to its position at the end of the Virgin Islands archipelago).
Culebra is a popular weekend tourist destination for mainland Puerto Ricans, Americans and residents of Vieques. Culebra has many beaches including Flamenco Beach (Playa Flamenco), rated third best beach in the world for 2014 by TripAdvisor. In November 2017 Forbes rated it #19 of the top 50 beaches around the world. It can be reached by shuttle buses from the ferry. The beach extends for a mile of white coral sand and is framed beautifully by arid tree-covered hills. The beach is also protected by the Department of Natural and Environmental Resources as a marine wildlife reserve.
The area west of Flamenco Beach and the adjacent Flamenco Point were used for joint-United States Navy/Marine Corps military exercises until 1975. Two old M4 Sherman tanks, which were used for target practice, can be found at the beach. Culebra and Vieques offered the U.S. military training areas for the Fleet Marine Force in amphibious exercises for beach landings and naval gunfire support testing. Culebra and Vieques were the two components of the Atlantic Fleet Weapons Range Inner Range. In recent years, only the shortened term “Inner Range” was used.
Other beaches are only accessible by private car or boats. Of the smaller islands, only Culebrita and Luis Peña permit visitors and can be accessible via water taxis from Culebra. Hiking and nature photography are encouraged on the small islands. However, activities which would disturb the nature reserves are prohibited, e.g. camping, littering and the use of motor vehicles. Camping, however, is allowed on Flamenco Beach throughout the year. Reservations are recommended. Culebra is also a popular destination for scuba divers because of the many reefs throughout the archipelago and the crystal clear waters. Because of the “arid” nature of the island there is no run-off from rivers or streams, resulting in very clear waters around the archipelago.
