The National Park Service is considering implementing “peak season pricing” in 17 of the country’s most popular parks, proposing an increase to $70 per car. Currently, Yellowstone charges $30 per vehicle, or $50 for Yellowstone and Grand Teton.

The parks proposed for the increase would be: Arches, Bryce Canyon, Canyonlands, Denali, Glacier, Grand Canyon, Grand Teton, Olympic, Sequoia & Kings Canyon, Yellowstone, Yosemite, Zion, Acadia, Mount Rainier, Rocky Mountain, Shenandoah, and Joshua Tree, per the NPS.
