 Snorkeling is excellent, especially at Blue Beach (Bahía de la Chiva).Aside from archeological sites, such as La Hueca, and deserted beaches, a unique feature of Vieques is the presence of two pristine bioluminescent bays, including Mosquito Bay.Vieques is also famous for its paso fino horses, which are owned by locals and left to roam free over parts of the island.
