2018 - National Park Service
Bad news, nature lovers: the National Park Service has slashed its no-cost admission days by 60 percent for 2018.
On Dec. 12, the NPS announced that visitors will be welcomed free of charge on just four days of the New Year — Martin Luther King Jr. Day, Jan. 15; the first day of National Park Week, April 21; National Public Lands Day, Sept. 22; and Veterans Day, Nov. 11.
The decree applies to 118 of the 417 national parks that charge an entry fee, including beloved preserves such as the Grand Canyon, Yellowstone, Yosemite and Zion.

Our park Rocky Mountain National Park went from $20 day pass to $70 day pass. I guess whatever it takes to keep them from privatizing, because then things really go to heck.
However, that day pass is good for 7 days.
Then that's not too bad then. Kind of bad for the one day drive through tourist, but not the camper.
Of course if you are old enough - 62+, even at $80 the lifetime pass is a great deal.
