Admission to all national parks will be free on Jan. 18 in honor of Martin Luther King, Jr. Day, the park service has announced.
The discount gives visitors a chance to skirt the $25 fee for entering sites likes the Grand Canyon in Arizona or Yellowstone in Montana, Wyoming and Idaho.
The MLK Day promotion is part of events commemorating the National Park Service’s centennial. There will be 16 days in all this year in which admission is free to parks and historical sites run by the NPS.
