Dry Tortugas National Park is a spectacular cluster of seven islands that sit 70 miles away from Key West, but the only practical way to get there is by booking a half-day flight with Key West Seaplane Adventures ($265 per person), the only charter plane company licensed to fly there. During the 40-minute flight, you’ll spot marine life, shipwrecks, and an active treasure site where half a billion dollars' worth of loot has been found. Once you arrive, you can tour Civil War–era Fort Jefferson and snorkel in the reef.
