1. Dry Tortugas National Park is a beautiful and unique destination located approximately 68 miles west of Key West, Florida. The park is made up of seven small islands, including Fort Jefferson, which is the largest brick masonry structure in the Western Hemisphere. The waters surrounding the park are clear and teeming with marine life, making it a popular spot for snorkeling and diving. The Dry Tortugas is also home to a variety of bird species, including the Brown Noddy and Sooty Tern. Visitors can explore the fort, take a guided tour, go camping, and enjoy swimming and snorkeling in the crystal clear waters.

2. The park is open year-round, but hours of operation vary depending on the season. The visitor center is generally open from 8:00 am to 5:00 pm daily. The park does not have a phone number, but visitors can contact the National Park Service on their website or email them for information.

3. Tickets can be purchased online or in-person at the ferry terminal in Key West. The ferry, operated by the Yankee Freedom III, runs daily from Key West to the park. The price of the ferry varies depending on the season and age of the visitor. Camping permits are also available for those who want to stay overnight on the island.
