Dry Tortugas Beach. Source: Nagel Photography / shutterstock Dry Tortugas Beach. Approximately 90 miles from Key West, Dry Tortugas Beach is located within the Fort Jefferson National Park. Spending your day at the beach here is one of the best things to do in Key West.

Head 70 miles west of key west (112 km west of key west) and you’ll reach a remarkable group of islands called the Dry Tortugas. Remote and isolated, the islands are almost entirely undeveloped by man and a haven for wildlife.
