Sedona is a very popular area for very good reason, and because of its popularity, the U.S. Forest Service implemented a user fee for some of the more heavily used areas called the Red Rock Pass Program. As stated on their site:
A Red Rock Pass can be purchased on a daily, weekly or annual basis. The Daily Pass is good for one calendar day and costs $5. The Weekly Pass is good for 7 consecutive days at costs $15. And finally, the Annual Pass is good for 12 consecutive months and costs $20.
An America The Beautiful Interagency Pass, Senior Pass or Access Pass also qualifies for access to these areas. If you are going to the Grand Canyon and possibly other parks, national monuments, historic sites, recreation areas, as well as many other public sites, an America The Beautiful Interagency Pass is a great pass to consider purchasing. It is good for an entire year and will give you access to all of these sites for a one time price of $80. That’s quite a bargain when you consider that Grand Canyon alone costs $35!
One of these passes must be displayed in the windshield of your vehicle whenever recreating on National Forest land in Red Rock Country. A pass is not required for incidental stopping to take a photograph or to enjoy a scenic vista (approximately 15 minutes or less). Vehicles parked on the National Forest in the red rock area that do not display a valid pass in the windshield are subject to receiving a citation.
