From the impressive diversity of the El Yunque rainforest to one of the largest cave networks in the world, the Camuy Caves, Puerto Rico is filled with natural beauty to 
discover. Relax on one of the island’s many tropical beaches. Stroll through some of Puerto Rico’s 36 natural reserves, 19 state forests, and five wildlife refuges. Want more than an adrenaline rush? There’s zip-lining, climbing, rappelling, snorkeling, scuba diving, and much more. 
This practical destination is filled with authentic and unusual experiences, from local markets to art museums and performances by local musicians, from the colonial city in old San Juan to preserved islands like Vieques and Culebra.
With a coastline of nearly 300 white sand beaches to labyrinth-like caves and bioluminescent pools, there is much to explore here. In fact, Puerto Rico is home to three of the five bioluminescent bays in the world (Laguna Grande in Fajardo, Mosquito Bay in Vieques, and La Parguera in Lajas). These bays offer inspiring views at night, filled with millions of unicellular organisms that light up the water like bright stars 
. The island also hosts several caves, including Cueva Ventana and the famous Río Camuy Caves.
Visit the only subtropical forest in the U.S., El Yunque National Forest, to see the wide variety of plant and animal species – some 
found only here. Located in the northeast of Puerto Rico, the forest has several hiking trails and also hosts ancient petroglyphs. You’ll want to explore some of the secular buildings, including fortresses and museums of historical importance.
Puerto Rico is a group of islands in the Caribbean, a former Spanish colony that is now a U.S. territory. The 
Spanish heritage of the archipelago remains prominent today in many ways, from architecture to food, music, and language. English is also widely spoken, and the U.S. dollar is used throughout the island. Visiting Puerto Rico is as simple as visiting any U.S. state. A bonus: temperatures year-round range from 21 to 27 degrees Celsius.
