GRAND CANYON NATIONAL PARK, AZ - The National Park Service turns 98 years old Monday and is waiving entry fees across the country in celebration.
Getting into the Grand Canyon and other national park units in Arizona will be free. Fees for camping, reservations, tours or use of concessions still apply.
Visitors who spent time in the park beyond Monday will have to pay the regular entrance fee for the rest of their stay.
The Park Service was established on Aug. 25, 1916 and includes 401 park units.
The agency plans to let visitors in free on two more days this year -- National Public Lands Day on Sept. 27 and Veterans Day on Nov. 11.
