Dry Tortugas National Park is the most remote national park in the lower 48. This chain of islands sits about 70 miles west of Key West, Florida. Its remote location makes it one of the least visited National Parks in the United States. Dry Tortugas National Park is made up of seven small islands and the surrounding reefs and oceans. The park has a rich history with Fort Jefferson and it’s ties to President Abraham Lincoln’s assassination. Today, visitors to Dry Tortugas National Park can explore the fort and enjoy some of the best coral reefs in the United States.
