Dry Tortugas National Park is a collection of 7 islands that are located approximately 70 miles from Key West, Florida in the United States. The most distinct feature of Dry Tortugas is that 99% of the 100-square mile National Park is located beneath the Gulf of Mexico's water with it consisting of protected coral reefs. It is also one of the least visited National Parks in the United States with an average of 60,000 visitors each year.

  • Booking reservations/tickets in advance is highly recommended due to a high demand paired with a restricted number of spots

  • Items to bring include: Bathing Suit & Beach Towel, Camera, Sunglasses & Hat, Snorkeling Gear – Optional, Sunscreen, Binoculars, Sturdy Pair of Walking Shoes, Change of clothing

  • Motion Sickness pills or patches are good to have, the sea can definitely get rocky and make the ride there or back brutal

  • The rental snorkeling gear is not the greatest, so bringing your own like stated above would lead to a better experience

  • The isolated nature of the National Park means that there will be no cellular service, so plan accordingly

  • If visiting by Ferry, have an idea of how to use your limited time so as not to feel lost on arrival

Dry Tortugas National Park is Absolutely Worth the Visit

Dry Tortugas National Park Beach

The United States has some of the most incredible National Parks available to visit ranging from immensely popular (Yellowstone, Grand Canyon, Zion) to least visited such as Dry Tortugas as the 3rd least visited within the contiguous 48 states. Not including the National Parks located within Alaska that are even less visited as well as difficult to visit, Dry Tortugas National Park most certainly has a higher price point and difficulty to visit than average ones located throughout the states.

Dry Tortugas National Park Reefs

The raw beauty of the park is something you don't get from most of the other National Parks to visit though. It is also a great park to combo a visit to Everglades National Park with due to the similar ecological environment that has its own distinct beauty.
