Vieques is a nature-lover’s dream, with wild horses wandering empty beaches, turquoise water, and huge stretches of protected wildlife refuge. By day, guests can snorkel, kayak, or simply bar-hop along uncrowded shores; by night, the world-famous Bioluminescent Bay glows electric blue under the stars. It feels remote enough to be an escape, but small and laid-back enough that everyone quickly slips into the same easy island rhythm.
