Permits are not required for a long-distance hike or ride along the Arizona Trail; however, permits are required for overnight camping within a few areas. These permits are not managed by the ATA; you will need to contact each agency directly. Here are the permits you may need:

Colossal Cave Mountain Park (Passage 8)

Has a fee and you must stay in the designated campgrounds of La Selvilla or El Bosquecito. Colossal Cave website.

Saguaro National Park (Passage 9)

Requires park entrance and camping permits for all hikers. Camping is only allowed in developed campgrounds (Grass Shack and Manning Camp). To learn more about backcountry camping at Saguaro visit their park website. Park entrance permits can be obtained through Pay.gov, and camping permits can be obtained through Recreation.gov. Permit compliance is strictly enforced.

Grand Canyon National Park (Passage 38)

Requires a camping permit and camping is only allowed in developed campgrounds (Bright Angel and Cottonwood). Although Grand Canyon backcountry permits can be very challenging to obtain, the Park’s Backcountry Information Center is authorized to make a special accommodation for AZT thru-hikers by issuing up to one permit per night for an AZT group to camp in the “stock site” if it is available (the stock site is normally held for equestrian groups). There is one stock site at Bright Angel Campground and one at Cottonwood Campground. When you visit the Backcountry Information Center let them know you’re an AZT thru-hiker and that you would really appreciate the opportunity to camp at Cottonwood and/or Bright Angel. Remind the ranger about the stock site option and ask if it is still available. Attempting to camp in Grand Canyon without a permit is not recommended and will guarantee you a big ticket . . . this is, after all, one of the most heavily patrolled parks in the National Park system.

Arizona State Trust Lands

A 15-foot wide right of way for the Arizona Trail has been obtained so you can cross approximately 91 miles of State Trust Land without a permit (mostly on passages 6, 7, 14 and 15). If you plan on traveling outside the 15-foot corridor to camp, explore, etc. then it is recommended that you obtain a State Land Recreation Permit. They are only $15 and allow recreational access to almost 9 million acres throughout Arizona. Permits can be obtained through the Arizona State Land Department website.
