Commonly referred to as the “hidden islands of Puerto Rico,” Vieques and Culebra are located a short boat ride off the east coast of Puerto Rico.
With breathtaking scenery, the islands offer visitors a break from the hustle and bustle of mainland Puerto Rico. And each island has its claim to fame.
Vieques is home to Mosquito Bay, which the Guinness Book of World Records deemed the brightest bioluminescent bay in the world. And Culebra boasts Flamenco Beach that the Discovery Channel crowned the second-best beach on the planet.
The best time to visit Mosquito Bay is on nights with very little moonlight.
