2. Culebra
The polar opposite of San Juan’s urban eclecticism and just a short flight away, sleepy Culebra has no mega resorts or nightclubs. On this Puerto Rican island you’ll enjoy unspoiled, natural beauty with few other visitors. Most lodgings are guest houses or small inns and visitors spend their days on world-famous Flamenco Beach, dining in small home-style restaurants and snorkeling in clear turquoise water.
