Common questions

What is the America the Beautiful Interagency Pass?

The America the Beautiful National Parks and Federal Recreational Lands Pass costs $80 annually and covers entrance fees at over 2,000 federal recreation sites across the National Park Service, US Forest Service, and BLM.

Do I need a reservation to enter US National Parks?

Several highly visited parks (including Yosemite, Glacier, Rocky Mountain, and Zion for Angels Landing) require timed vehicle or trail reservations during peak summer months to manage congestion.

How far in advance should I book park campsites?

Most National Park campgrounds open for reservations on Recreation.gov 6 months in advance on a rolling basis, and peak summer sites at Yellowstone, Yosemite, and Glacier often book out within minutes of release.
