Puerto Rico Facts & Travel Guide
Puerto Rico is one of the Caribbean's most varied destinations: a historic capital, mountain interior, tropical rainforest, long Atlantic and Caribbean coastlines, major surfing areas, coral reefs and the smaller islands of Vieques and Culebra. It is a U.S. territory, uses the U.S. dollar and combines Spanish-speaking Caribbean culture with close political and economic ties to the United States.
The island is large enough that a short beach stay shows only a small part of it. Old San Juan, El Yunque, the central mountains, the west coast, the dry southwest, Vieques and Culebra all feel substantially different.

Old San Juan
Old San Juan is the most concentrated historic area on the island and one of the oldest European-founded urban centres in the Americas. The walled district is best explored on foot. Its major landmarks include Castillo San Felipe del Morro, Castillo San Cristóbal, the city walls, plazas, churches and streets lined with colourful historic buildings.
San Juan is much more than the old city. Condado, Ocean Park, Santurce and Isla Verde provide a modern urban contrast, with restaurants, beaches, nightlife and a large accommodation base.
El Yunque and the northeast
El Yunque National Forest is the only tropical rainforest in the U.S. National Forest System. It lies within easy reach of San Juan but deserves more than a quick roadside stop. Waterfalls, mountain views, forest trails and rapidly changing weather make it one of Puerto Rico's defining landscapes.
The central mountains
Puerto Rico's interior is crossed by the Cordillera Central. The roads become slower and more winding, and the scenery shifts from coastal development to forest, farms and mountain towns. Coffee-growing areas around Adjuntas, Jayuya and Lares offer a very different side of the island from San Juan or the resort coast.
West coast and southwest
Rincón and the northwest are well known for surfing, especially during the northern swell season. Farther south, the landscape becomes drier around Cabo Rojo, Guánica and La Parguera. The southwest combines salt flats, dry forest, mangroves, offshore cays and sheltered Caribbean waters.
Culebra and Vieques
Culebra and Vieques lie east of the main island and are reached by ferry from Ceiba or by short flights. Culebra is best known for beaches such as Flamenco Beach and clear water for swimming and snorkelling. Vieques is larger, has extensive protected land, wild horses and Mosquito Bay, one of Puerto Rico's best-known bioluminescent bays.
Isla Mona
Isla Mona lies far to the west in the Mona Passage between Puerto Rico and Hispaniola. It is a protected natural reserve rather than a normal tourism island. Reaching it requires sea transport and advance planning, and visits or camping require authorization from Puerto Rico's Department of Natural and Environmental Resources (DRNA).

| Language in practice | English is common in many tourism settings, but Spanish is much more useful for travelling independently across the island. |
