Long considered the gateway to Latin America, Miami is as close to Cuba and the Caribbean as you can get within the United States. The 36-square-mi city is located at the southern tip of the Florida peninsula, bordered on the east by Biscayne Bay. Over the bay lies a series of barrier islands, the largest being a thin 18-square-mi strip called Miami Beach. To the east of Miami Beach is the Atlantic Ocean. To the south are the Florida Keys.
