Loggerhead Key Lighthouse, on a remote island in Dry Tortugas National Park, dates to 1858. It's so secluded that would-be visitors must make arrangements in advance through the National Park Service. The conical tower stands more than 150 feet tall and the kitchen in the quarters below is used by park service volunteers. Access to the park is by boat or seaplane only.
