We spent 2 weeks in Puerto Rico in June/July 06. The diving and snorkeling were fantastic. If you want to get away from it all, go to the PR island of Culebra, where there is a fantastic marine sanctuary easily accessed from shore for snorkeling. However, also make an overnight trip to Vieques, another of the PR islands, for a night swim in the Bioluminescent Bay, said to be the best in the world. It truly was magical. Watch for the wild horses on Vieques! We will spend a week on Culebra and a week on Vieques next summer.
