YELLOWSTONE NATIONAL PARK, Wyo. (AP) — Visitors to Yellowstone and other national parks will be admitted free on National Public Lands Day, Sept. 28.

A seven-day pass to Yellowstone and Grand Teton National Parks usually costs $25 for private vehicles. Camping fees and other fees will still apply on National Public Lands Day.

The Park Service is waiving entrance fees to encourage people to visit national parks.

The agency plans to waive entrance fees on November 9-11 to mark the Veteran's Day holiday.
