Trail Route Description
From the Casa Blanca Canyon Road Trailhead, follow the AZT west through the foothills of the Santa Rita Mountains. The trail (built in 2020 and 2021 as part of the Temporal Gulch Reroute Project) delivers you to Temporal Gulch Trailhead after 13.5 miles. From here, follow Temporal Canyon Road (FR 72) north toward Walker Basin Trailhead in Walker Canyon. After passing Upper Walker Tank it crosses a saddle and then descends, working its way east into Casa Blanca Canyon. It goes by Bear Spring, crosses several drainages and then comes to the Tunnel Springs Trailhead. From here it heads east and then follows the old flume north and east up to Gardner Canyon Road.
NOTE: A new segment of Arizona Trail is currently under construction, which will remove the AZT from Harshaw Road and Temporal Canyon Road. We anticipate completion of this project by Spring of 2023. Once completed, the mileage and passage route will change. Check out the Casa Blanca Canyon Trailhead Sign for more details on the current route, and the segment still under construction. For those wanting to access the Town of Patagonia, please follow the Patagonia Train Track Trail just east of Highway 82 — which connects the AZT in Casa Blanca Canyon with the Post Office in the Town of Patagonia (4.5 miles).
