Smallest national parks in the United States

The smallest American parks in the catalogue are islands and coasts: the Boston Harbor Islands, the Virgin Islands park on St John, the reef reserve of La Cordillera off Puerto Rico, and Haleakala on Maui, with the narrow Black Canyon of the Gunnison the mainland exception. The very smallest national parks in the system, Gateway Arch and Hot Springs, are urban sites that the catalogue does not cover.
