• Highway 82 to Gardner Canyon Road


  • 28.5 miles

Southern Access Point: Casa Blanca Canyon Trailhead


From the north, follow Highway 82 toward the town of Patagonia. Four miles north of town, turn right/west on Casa Blanca Canyon Road. Follow this dirt road west for 1/4-mile and look for the trailhead on your left/south. Park here, walk through the AZT gate, and follow the Connector Trail for 1/3-mile to locate the Arizona Trail. There is no parking or access along Highway 82; instead please use the Casa Blanca Canyon Trailhead nearby.

Northern Access Point: Gardner Canyon Road


From Sonoita, follow AZ 83 north 4 miles and turn left (west) onto Gardner Canyon Road (FR 92). Avoid side roads. You’ll reach the Gardner Trailhead (not to be confused with Gardner Canyon Trail, which is farther west) 5.5 miles from the highway on the right side of the road. There is a large parking area here.

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).

Your support is needed to help us reach our fundraising goal this Spring to support construction of the Temporal Gulch Reroute Project. Please DONATE securely online today! Our goal is to raise enough money between March 22 - April 3 to sustain the next phase of trail construction. This project will remove the AZT from 17 miles of paved and dirt roads near the town of Patagonia with 32 miles of sustainable singletrack. This improvement will make the Arizona Trail safer, more scenic, and will be our largest trail construction project in recent history. Whether you hike, run, pedal or ride, we can't wait for you to experience the AZT through the Casa Blanca Canyons with Mt. Wrightson towering in the background! Please donate today and encourage your trail loving friends to do the same. Donors giving $25 or more will receive a limited-edition sticker in the mail as a small token of thanks.

Two people bitten by animals in separate incidents in Southern Arizona

Arizona Daily Star (March 6, 2020) by Gloria Knott Two people were bitten by animals in separate incidents in Southern Arizona yesterday, wildlife officials say.  A fox bit a person on the ankle in Sabino Canyon on Thursday, according to Arizona Game and Fish Department spokesman Mark Hart. In another incident, a skunk bit a man in the face while he was asleep at a campground near the Arizona Trail in the Santa Rita Mountains. Both incidents happened within an hour of each other, Hart said. In both incidents, the bite victims killed the animals after feeling that the animals' behaviors were abnormal. The animals are being tested for rabies. Both bite victims are getting treated for possible rabies.  Anyone needing Game and Fish assistance should call 623-236-7201.
