Dry Tortugas National Park is located in the Gulf of Mexico, about 68 miles off the coast of Key West, Florida. The park covers 100 square miles, including seven small islands made up of coral reefs and sand. It is a popular destination for snorkeling, scuba diving, fishing, and birdwatching.

One of the main attractions of the park is Fort Jefferson, a massive brick fortress that was built in the 19th century to protect the shipping lanes in the Gulf of Mexico. Visitors can take guided tours of the fort and learn about its history and significance.

Another popular activity in the park is snorkeling at the coral reefs surrounding the islands. The crystal-clear waters are home to a diverse array of marine life, including colorful fish, sea turtles, and even shipwrecks.

Dry Tortugas National Park is also a haven for birdwatchers, with more than 300 species of birds that call the islands home, including rare and endangered species like the roseate tern and the brown noddy.

The best time to visit Dry Tortugas National Park is in the winter months, from December to April, when the weather is mild and the seas are calmer. The park can be accessed by ferry or seaplane from Key West, and camping is available on the islands for those who want to stay overnight.

Overall, Dry Tortugas National Park is a unique and beautiful destination that offers a variety of outdoor activities and opportunities to explore history and nature.
