The Trump administration announced Tuesday that the entrance fee to 17 national parks may be increased up to $70 per car.
The parks include Yosemite National Park, Grand Canyon National Park and Yellowstone National Park.
Interior Secretary Ryan Zinke said the increase will go toward maintenance costs such as repairing roads, bathrooms and campgrounds.
The potential fee increase would affect the parks during “peak season” when attendance is highest. The remaining months would stay at the regular price.
The current price to enter the park is $25 to $30 per car.
A final decision by Zinke will be made within the next few months.
