San Juan, officially Municipio de la Ciudad Capital San Juan Bautista (Municipality of the Capital City, Saint John the Baptist), is the capital and most populous municipality in Puerto Rico, an unincorporated territory of the United States. As of the 2000 census, it has a population of 658,304 making it the 42nd-largest city under the jurisdiction of the United States. San Juan was founded by Spanish colonists in 1521, who called it Ciudad de Puerto Rico ("Rich Port City"). Puerto Rico's capital is the second oldest European-established city in the Americas, after Santo Domingo, in the Dominican Republic. Several historical buildings are located in San Juan; among the most notable are the city's former defensive forts, Fort San Felipe del Morro and Fort San Cristóbal, and La Fortaleza, the oldest executive mansion in continuous use in the Americas. 

Saint Kitts and Nevis are a pair of tropical islands in the Caribbean and the smallest sovereign state in the Americas, in both area and population. The country is a Commonwealth realm, with the British Monarch (currently, Elizabeth II) as its head of state.  Saint Kitts and Nevis were among the first islands in the Caribbean to be settled by Europeans. It was home to the first British and French colonies in the Caribbean, and thus has also been titled "The Mother Colony of the West Indies''. The natural aspect is what makes the country remarkable. Many tropical birds which one rarely finds elsewhere are present in great concentration in the nature and there are also the famous monkeys which, it is said, were introduced by the pirates      

Saint Croix is an island in the Caribbean Sea, and a county and constituent district of the United States Virgin Islands (USVI), an unincorporated territory of the United States. It is the largest of the U.S. Virgin Islands, being 28 by 7 miles (45 by 11 km). However, the territory's capital, Charlotte Amalie, is located on Saint Thomas. St. Croix, like many other Caribbean islands, has tourism as one of its main sources of revenue. However, there are a number of other industries on the island to help support the economy. St. Croix was once an agricultural powerhouse in the Caribbean, but ended with the rapid industrialization of the island's economy in the 1960s. Buck Island Reef National Monument preserves a 176 acre (71 ha) island just north of Saint Croix and the surrounding reefs. This is a popular destination for snorkelers.
