Yes, really, for free.

In honor of National Public Lands Day, all national parks will be free to visit on Saturday, Sept. 27.

However, they’re really popular, so it’s highly recommended that you plan to arrive at dawn. It will be cooler and the crowds will still be waking up. (Don’t tell anyone, though, it will get more crowded.)

When the park starts getting crowded, you can take a break and eat the picnic you’ve brought, or head on out.  Don’t forget to bring plenty of water!

Note that the freebies don’t include camping or special tours.

Some parks have free entry year-round, but the admission-waiving sites in Florida are:

Canaveral National Seashore
Castillo de San Marcos National Monument
Dry Tortugas National Park
Everglades National Park
Gulf Islands National Seashore

The next national park holiday will be on Veterans Day, Nov. 11.
