The U.S National Park Service is celebrating the 25th anniversary of National Public Lands fee-free on Sept. 22.
Visitors who visit any federally managed lands will be allowed to enter the park free of charge. There are more than 400 parks from coast-to-coast eligible for free admission on Sept. 22.
The fee-free designation does not affect fees for camping, reservation, tours or use of concessions.
Visitors who plan on spending time in the parks beyond Sept. 22 will need to pay the regular entrance fee for the remainder of their stay.
Many Florida State Parks also have events planned for Saturday.
In Southwest Florida, several parks have events planned.
J.N. "Ding" Darling National Wildlife Refuge on Sanibel Island is offering free admission to Wildlife Drive, offering a guided tour and clean-up of the Indigo Trail, and offering discounts on bike and kayak rentals.
Lover's Key State Park is offering free admission to the park and hosting a Public Lands Workday for volunteers to help maintain the park's trails.
Collier-Seminole State Park in Naples is hosting a park clean-up and air potato round-up at 9 am.
The next fee-free day will be November 11, in honor of Veterans Day.
