I like to be on Vieques, this island is Safety for travelers. Renting kaycks and you will get an amazing experiece to swim in the bioluminescent bay Vieques island. Visit my favorite website about Vieques: vieques villa. To explore Vieques we highly commend you rent a car. Did you see all Vieques beaches? I rented a JEEP in Vieques in November of 2009 including my Husband. You cannot miss the bio bay tour on Vieques… there is truly nothing like it anywhere else in the Carribean. The beaches of Isla de Vieques has some of the clearest azure blue water on the island and terrific snorkeling along the eastern end….
