Staten Island (Richmond County: Pop. 481,613) is the most suburban in character of the five boroughs. Staten Island is connected to Brooklyn by the Verrazano-Narrows Bridge and to Manhattan via the free Staten Island Ferry. The Staten Island Ferry is one of the most popular tourist attractions in New York City as it provides unsurpassed views of the Statue of Liberty, Ellis Island, and lower Manhattan. Located in central Staten Island, the 25 km² Greenbelt has some 35 miles (56 km) of walking trails and one of the last undisturbed forests in the city. Designated in 1984 to protect the island’s natural lands, the Greenbelt comprises seven city parks. The FDR Boardwalk along South Beach is 2.5 miles (4.0 km) long, the fourth largest in the world.
