There is no end to the entertainment possibilities on Puerto Rico-snorkeling, golfing, and shopping are just a few of the things to do while on the island. A great source of information about what the island has to offer is the staff at your villa on Puerto Rico or other rental property. These locals can point out some of the lesser-known gems that offer glimpses of the island outside the tour books. If you'd rather stay on the beaten path, try a day excursion for snorkeling and diving just offshore, or head to Rio to see Camuy Park's great subterranean caverns-a huge network of underground caverns. For an experience right out of a sci-fi movie, take a trip to Bioluminescent Bay. Here the micro-organisms in the water will turn you into a human glow-stick as you float in the unusual blue/green waters. All of these attractions just minutes from your Puerto Rico villa.
