In the middle of the Caribbean there is a Spanish-speaking part of the United States. Or more accurately, an unincorporated territory of the United States. It was ceded under the Treaty of Paris which ended the Spanish-American War of in 1989. In 1917, Puerto Ricans were granted US citizenship, and more Puerto Ricans now live in the U.S. mainland than in the archipelago.
Puerto Rico's population is mostly white (76%), though 12.5% are black or African American. Spanish is the dominant language. Roman Catholicism is the largest denomination (38%) though a majority of the population are protestant, with 28% Pentecostalists, 4% Baptists, and 18% members of other denominations.
Puerto Rico has a tropical marine climate, which is mild and has little seasonal temperature variation. Temperatures range from 21C to 32C (70F to 90F), and tend to be lower at night and up in the mountains. Year-round trade winds help ensure the sub-tropical climate. The average annual temperature is 26C (80F). Rainfall is light on the south coast, though there is a hurricane season from June to November, with rain showers occur once a day almost every day.
Puerto Rico is mostly mountainous, although there is a coastal plain belt in the north. The mountains drop precipitously to the sea on the west coast. There are sandy beaches along most of the coast.
Since Puerto Rico is a U.S. territory, travellers from outside the United States must meet the same requirements needed to enter the United States. For travel within the United States, there are no passport controls between the US mainland and Puerto Rico, or vice versa. The currency is the U.S. dollar.
San Juan is the capital. Old San Juan remains partly enclosed by massive walls, with notable forts, such as the Fort San Felipe del Morro, Fort San Cristobal, and El Palacio de Santa Catalina, also known as La Fortaleza (now the executive mansion for the Governor of Puerto Rico). Old San Juan City has 500-year-old cobblestone streets, tile roofs, ornate balconies and the heavy wooden doors guarding secret courtyards and gardens that are perfect examples of the Spanish influence in the Puerto Rican architecture.
The second city Ponce is very attractive to visit on foot.
