Imagine stepping off a boat onto pristine white sand beaches where crystal-clear turquoise waters meet one of America’s most historically fascinating fortresses – all while being completely surrounded by nothing but endless ocean horizons.
Dry Tortugas National Park sits almost 70 miles west of Key West, making it one of the most remote and least visited national parks in the United States.
This extraordinary marine sanctuary combines the largest brick masonry structure in the Western Hemisphere with some of the most pristine coral reefs in North America.
What makes this destination truly special is that 99 percent of the park lies underwater, protecting an incredible ecosystem that has remained largely undisturbed.
You’ll find yourself in a place where history and nature converge in the most spectacular way – from snorkeling alongside massive tarpon and colorful tropical fish to exploring the haunting corridors of Fort Jefferson, where Civil War prisoners once walked.
