Entrance fees at Theodore Roosevelt National Park in western North Dakota and all other national parks in the country will be waived Sunday, Aug. 25, to commemorate the 103rd birthday of the National Park Service.

Two more free days remain this year, including National Public Lands Day on Saturday, Sept. 28, and Veterans Day on Monday, Nov. 11.

The two other national park units in North Dakota -- Fort Union Trading Post Historic Site near Williston, N.D., and Knife River Indian Villages Historic Site near Stanton, N.D. -- are among the more than 200 national parks that never charge entrance fees.
