Northern Trailhead: Pigeon Spring/Lone Pine Saddle Trailhead

Access

From the suspension bridge near Roosevelt Dam, drive north on AZ 188 for 11 miles and turn left (west) at mile marker 255 onto El Oso Road. At 4.4 miles from the highway, the road appears to fork. Take the sharp right turn and follow the road as it climbs. Continue another 4.2 miles to an intersection with FR 422, which is the path of the AZT to the north. The AZT arrives from the southeast (left) on FR 143. Drive 1 mile on FR 143 to an intersection, bear left onto FR 648, and continue almost another mile to Pigeon Spring Trailhead on the left.

Alternatively, to reach a larger, more developed parking area and trailhead at Lone Pine Saddle, continue 0.5 miles ahead. Parking here allows you to hike on singletrack into the Four Peaks Wilderness and meet the AZT in about 2 miles.


Trail Route Description

Passage 20 ascends from Theodore Roosevelt Lake into the Four Peaks Wilderness. The trail traverses high ridges with significant elevation gains and panoramic views of the Superstition Wilderness, Four Peaks, Roosevelt Lake, and Apache Lake.

This route begins with a steep ascent overlooking Theodore Roosevelt Bridge. On the way up, the trail follows a well maintained singletrack that winds its way across rocky switchbacks, up scenic ridgelines, and through grassy hillsides, lined with desert succulents, shrubs, wildflowers, and a variety of cacti. 

Within the Four Peaks Wilderness, the trail levels off and gradually traces its way along the foothills of Four Peaks – a single, prominent mountain within the Mazatzal Range with four distinct peaks that can be seen from great distances.
