The United States is a country-continent surrounded by two oceans. By taking the ferry from New York, Los Angeles or Fort Myers, you will access small, atypical islands that can be visited for the day.
Visit Ellis Island in New York Bay, Nantucket in Massachusetts, Alcatraz and Catalina Island in California, and Sanibel off the coast of Florida. In the 17th and 18th centuries, whaling was the island's main activity. The island is also extensively cited in Moby Dick by Herman Melville.
