This probably won’t shock you, but the proposal to hike the cost of a one-week pass at the 17 most visited national parks (including Rocky Mountain) has generated a lot of feedback.

For that reason, the National Park Service is extending its deadline for the public to give feedback from Nov. 23 to Dec. 22. At this point, they’ve already gotten more than 65,000 comments on the proposal, which the park service says will “generate needed revenue for improvements for aging infrastructure.”

The cost increases would only happen during peak season.

The fee hike would be implemented at Arches, Bryce Canyon, Canyonlands, Denali, Glacier, Grand Canyon, Grand Teton, Olympic, Sequoia & Kings Canyon, Yellowstone, Yosemite, and Zion National Parks with peak season starting on May 1, 2018; in Acadia, Mount Rainier, Rocky Mountain, and Shenandoah National Parks with peak season starting on June 1, 2018; and in Joshua Tree National Park as soon as practicable in 2018, according to a news release from the national parks service.

You can get a year pass for any of the parks for $75, or a pass to all of them for $80.
