Forts, beaches, jungles, salsa beats — Puerto Rico packs a lot into its 3,500 square miles. For close proximity to the popular beaches of Isla Verde, chic shops of Condado and coquis (tree frogs) of El Yunque rainforest, make the capital city of San Juan your home base. Historic Old San Juan, with its cobblestone streets and nearly 500-year-old fortress, is a city within the city. Rincon, a surfing hot spot in the northwest, offers intimate strands where the Atlantic Ocean meets the Caribbean Sea. Or get even more remote on the island of Vieques, six miles off Puerto Rico's eastern tip.
