It is seven small islands and the water around them, about 100 square miles in all, and its centerpiece is Fort Jefferson on Garden Key, the largest masonry fort in the western hemisphere. Entry is $15 for each person 16 or older, good for seven days; the ferry ticket includes it, the seaplane collects it before leaving Key West, and private boaters buy it through Recreation.gov. The park does not take cash. Nothing is sold inside the park, so bring your own food and drink. Garden Key has campsites, first come, first served, at $15 a site a night, and coral reefs to snorkel around the island.
