CAMP OUT ON AN ISLAND NATIONAL PARK
Around 70 miles offshore from the party town of Key West is its spiritual opposite: the remote island chain of Dry Tortugas, a national park accessible only by ferry or seaplane. Those who make it here are met by its sole landmark, the 19th-century brick-built Fort Jefferson. Less than one per cent of the park is dry land, and there’s water, water everywhere – though not a drop to drink. Campers bring all their own supplies and, after the daytrippers have departed, reap the rewards: exclusive access to miles of coral reef for swimming and snorkelling. At day’s end, it’s beachside barbecues before bedding down under a canopy of stars.
