Sun Bay Beach
Top 2 in Top 10 Best Puerto Rico Beaches
Isla Vieques (Vieques Island) is another Spanish Virgin Island destination surrounded by beautiful beaches, similar to Culebra. Isla Vieques is a 21-mile-long, five-mile-wide island off the coast of Puerto Rico that is home to the gorgeous Sun Bay Beach.
Sun Bay Beach in Vieques is one of the island's most popular beaches, with a broad expanse of sand and lots of parking and public facilities and showers. The island is also noted for a unique phenomenon in Bioluminescent Bay on certain nights (Mosquito Bay). The movement of a significant concentration of phosphorescent dinoflagellates causes the water in the bay to light when the conditions are right. You may join an after-dark boat, canoe, or kayak tour to see this natural beauty.
