Dry Tortugas National Park



About 70 miles from Key West lies Dry Tortugas National Park, seven islands that straddle the Gulf of Mexico, Caribbean Sea and Atlantic Ocean. The shallow waters surrounding the islands are perfect for snorkeling amid the ruins of Fort Jefferson. Tour the fort to learn about its construction and Civil War prisoners like Samuel Mudd--the doctor who assisted John Wilkes Booth after his injury. This remote park is only accessible by seaplane or ferry.
