Puerto Rico might be a small island, but it has big adventure. It is surrounded by more than 270 miles of beautiful coastline. Many of it's beaches offer you world-class surfing while others feature miles of reefs with plenty of marine life to admire. Not to mention, there are an endless number of activities you can do under the sun. Visit the Caribbean's oldest fortress, El Morro, in old San Juan or rappel down deep jungle caves filled with ancient tree roots and wildlife.
