(KTXL) — On five different days in 2023, all national parks will be offering free admission to anyone who wants to enter.

There are more than 400 national parks that are open daily. While some parks are free all the time, some of them require an entrance fee.

Here are the following days the parks will be free:

  • Jan. 16 — Martin Luther King Day
  • April 22 — First day of National Park Week
  • Aug. 4 — Anniversary of the Great American Outdoors Act
  • Sept. 23 — National Public Lands Day

The free days only cover the entrance fees to the parks and do not cover the costs of certain activities such as camping, boat launches, transportation or special tours.
