One of the best parts of Puerto Rico is curiously outside the island: Vieques. Until less than ten years ago, it was a U.S. military base and partially occupied by our country's navy. Due to some popular protests in 2003, the navy pulled out and the only thing left were beaches without tourists development of any kind. In other parts of the world, you could find some huge, all-inclusive hotels right next to to beaches like this, but here you'll find yourself practically alone. For a touch of adventure, you'll need a 4x4 to access many of the most beautiful beaches of Vieques and you'll have to go off-road.
