The two National Parks around the Florida Keys are both off shore of the islands. They are the Dry Tortugas National Park and Everglades National Park. Currently the entrance fees only apply to going on land at the parks and not to the waters surrounding the park land.

During fee-free days, the 124 national parks that charge entrance fees waive them for all visitors. The entrance fee waiver for the fee-free days does not cover amenity or user fees for things such as camping, boat launches, transportation, or special tours.
To continue the national park adventure beyond these fee-free days, the annual $80 America the Beautiful National Parks and Federal Recreation Lands Pass allows unlimited entrance to more than 2,000 federal recreation areas, including all national parks. There are also free or discounted passes available for senior citizens, current military members, fourth grade students, and disabled citizens.
