Southern Trailhead: Freeman Road Trailhead


From Mammoth, drive north on Hwy 77 to the town of Dudleyville. Turn left (west) on Dudleyville Road to the center of the community and locate San Pedro Road. Head west on San Pedro Road, where the road soon turns to dirt. Cross the San Pedro River (usually dry or very shallow) and then turn north at intersection and follow road north along the river (Camino Rio) for 0.5 mile. Turn left (west) on Freeman Road. Cross railroad tracks and continue for 12 miles to the trailhead.

Northern Access Point: Kelvin-Riverside Bridge


From the town of Superior, take AZ 177 south for 15.2 miles (MP 152.1) and turn south onto Florence-Kelvin Highway (next to RR crossing) for 1.2 miles through the community of Kelvin and cross the Kelvin Bridge. Passage 15 approaches the bridge from below the rock outcrop along the Gila River and ends at the south end of the old bridge. Parking is limited here since the new bridge was completed in 2018. Ample parking is available at the Florence-Kelvin Trailhead ~1.5 miles further west on the Florence-Kelvin Highway. Another option is the BLM trailhead at the end of Centurion Road (one-half mile into the passage northbound). Either location provides easy access to the Arizona Trail .

From Florence, drive 1.5 miles south on AZ 79 and turn left (east) on the dirt Florence-Kelvin Highway. Continue 31 miles to the town of Kelvin and a historic bridge over the Gila River.

From the town of Hayden/Winkleman, drive northwest on AZ 177 about 16 miles then south (left) toward Kelvin. Continue 1.2 miles to the bridge.

Trail Route Description

Passage 15 rolls across a remote section of the Sonoran Desert up to the foothills of the Tortilla Mountains, and then down to the Gila River. This section is hot, dry, and exposed but with a unique, rugged beauty that is synonymous with the desert. 


It features moderate miles along single and doubletrack trails through rolling desert terrain. The trail crosses sandy washes and several ranch roads, and passes large boulder piles and unique rock formations. It features mesquite trees, ocotillo, and cholla cacti, while spring wildflowers, such as yellow brittlebush, desert globemallow, and the magenta petals of the strawberry hedgehog cactus, line the trail and color the hillsides. 

The trail descends through Ripsey Wash and its forest of swollen saguaros, and then ascends into the foothills of the Tortilla Mountains. The toughest part of this section is the ascent up the “Big Hill,” a two-mile exposed climb with a series of switchbacks that leads to a scenic ridgeline with expansive views.  The scenery remains impressive as the trail continues across the ridge and eventually descends towards the Gila River.

The Wild, Wild West

BACKPACKER Magazine (May/June 2019) by Ryan Wichelns We talk about solitude like its last bastions are disappearing. But there's a place where isolation still rules and evidence of the last travelers is erased before the next ones arrive. You just have to head west to the vast wilds held by the Bureau of Land Management. There are few permits, fewer fees, and next to no people. It's all the solitude you can handle--and sometimes just a little more. For 800 miles, the Arizona Trail charges across its namesake, serving up equal parts desert glory and mountain grandeur. Within that, the BLM manages 45 lonely, dust-caked miles just east of Phoenix that pack in all the splendor but none of the crowds. And, according to the trailhead register, there's an average of just five visitors a day. Echo-o-o-o-o-o-o! To read the rest of the article, click here.
