Located within the crystalline waters of the Gulf of America lies a pristine oasis of natural beauty and historical significance: Dry Tortugas National Park. This remote and enchanting archipelago, comprised of seven small islands and surrounded by vibrant coral reefs, is a hidden gem waiting to be discovered by adventurous travelers. Located approximately 70 miles west of Key West, Florida, this remote national park offers a unique blend of marine biodiversity, rich history, and unparalleled solitude. Established in 1992, Dry Tortugas National Park encompasses 100 square miles of protected marine and terrestrial ecosystems, including Fort Jefferson, one of the largest 19th-century American coastal forts. The park’s name, derived from the Spanish word “tortugas” meaning turtles, pays homage to the abundant sea turtles that once inhabited these waters. Today, Dry Tortugas is celebrated for its pristine beaches, vibrant coral reefs, and unparalleled opportunities for snorkeling, diving, birdwatching, and historical exploration. Accessible only by boat or seaplane, Dry Tortugas National Park offers a secluded escape from the hustle and bustle of everyday life. Visitors can immerse themselves in the park’s natural wonders, exploring colorful coral reefs teeming with marine life, sunbathing on pristine sandy beaches, or wandering the historic corridors of Fort Jefferson. The park’s remote location and limited accessibility contribute to its pristine condition, making it an idyllic destination for nature lovers, history enthusiasts, and adventure seekers alike.

Frequently Asked Questions
Ready to dive into what Dry Tortugas National Park has to offer? Let’s tackle some of the burning questions you might have as you plan your visit!
-
You should stay in Key West, as it is the closest city to the park and offers various lodging options, since there is no lodging within the park boundaries. Key West is located at the end of the Overseas Highway and provides all necessary visitor services.
-
There are no child-friendly hiking trails since 99% of the park is underwater, and the only walkable area is a loop around Garden Key where Fort Jefferson is located. This loop is more of a walk than a hike. Other activities like snorkeling, exploring the fort, and observing wildlife are more prominent.
-
Pets are not allowed inside Fort Jefferson. Only service dogs are permitted, but they must be individually trained to assist a person with a disability. Other pets can only be on Garden Key and must be on a leash.
-
You can park your vehicle at the City Parking Garage on Grinnell Street in Key West, which is across the street from the Yankee Freedom Ferry Terminal. The garage offers shaded parking for $40 per day. There is no free parking available in the area.
-
The top attraction is Fort Jefferson, a massive six-sided fort built from 1846 to 1875 using 16 million handmade red bricks. It was constructed to protect the southern coastline of the United States and the strategic deepwater anchorage in the Dry Tortugas. The fort was never fully completed or attacked but played a crucial role in U.S. military history.
