Puerto Rico is a Caribbean island that is a self-governing commonwealth of the United States of America. Located in the Caribbean Sea to the east of the Dominican Republic and west of the US Virgin Islands, Puerto Rico lies on a key shipping lane to the Panama Canal, the Mona Passage.
Christopher Columbus landed on the island of Puerto Rico in 1493 on his second voyage of discovery, and originally named it San Juan Bautista in honor of Saint John the Baptist. The name of the island's present day capital, San Juan, honors the name Columbus first gave the island. It was then settled by explorer Ponce de Leon, and the island was under Spanish possession for over four centuries. Puerto Rico became United States territory under the Treaty of Paris, which also ended the Spanish–American War.
The U.S. Virgin Islands is an unincorporated organized territory of the United States of America between the Caribbean Sea and the North Atlantic Ocean, east of Puerto Rico. It was formerly known as the Danish West Indies. Together with the British Virgin Islands, to the northeast, the territory forms the Virgin Islands archipelago. These islands are in an important location along the Anegada Passage - a key shipping lane for the Panama Canal; Saint Thomas has one of the best natural deep water harbours in the Caribbean.
The terrain is mostly hilly to rugged and mountainous with little level land. There are occasional earthquakes. The highest point is Crown Mountain at 474m. During the 17th century, the archipelago was divided into two territorial units, one English and the other Danish.
The British Virgin Islands are a self-governing British overseas territory, situated in the Caribbean just to the east of the US Virgin Islands. The BVIs, as they are called, are a popular travel destination for sailors, fishermen, sun worshippers, and other independent travellers, albeit not for the cost conscious. Boating among the dozens of tiny, mostly uninhabited, islands is a great stop on any tour of the Caribbean islands.
The British Virgin Islands comprise 60+ islands and keys, with more than 43 of them being uninhabited islands. The islands fall into two types: the majority are steep volcanic islands (including the main islands, Tortola and Virgin Gorda), and a small number of relatively flat coral islands (such as Anegada and Sandy Spit). In fact, Anegada is referred to as »the drowned island« because its elevation is so low.
