Looking for a place to play Robinson Crusoe? Then head to Vieques, where you can wander along almost any stretch of sand and never see another soul. You can while away the hours underneath coconut palms, wade in the warm water, or get a mask and snorkel and explore coral reefs that ring the island.
For many years the island was known mostly for the conflict between angry islanders and aloof federal officials. Over the course of six decades the U.S. Navy used two-thirds of Vieques, mostly on the island's eastern side, as a bombing range, and the western tip as an ammunition dump. After an April 1999 bombing accident took the life of one resident, waves of protests brought the maneuvers to a standstill, and political pressure from the island's governor helped force the military to leave on May 1, 2003.
Ironically, the military presence helped keep the island pristine by keeping resort developers away. Today the military's former holdings have been turned into Vieques National Wildlife Refuge. The woodsy western end of the island is laced by trails that offer fabulous cycling around the base of Monte Pirata, the island's highest peak. More and more of the eastern part of the island is being opened every year, granting access to stupendous beaches shelving into calm turquoise waters. The park also protects Puerto Mosquito, a flask-shaped bay populated by microscopic organisms that glow when disturbed at night—a thrilling experience for kayakers.
