This Park comprises seven small islands and the crystal-clear water is ideal for swimming. Take the kids to see the awe-inspiring coral reefs, dandy shoals, sea life, and birds.

Fort Jefferson is located on 14-acre Garden Key, the second largest island in the Dry Tortugas. For more information and to book a stay visit here.
