Trail Route Description:  The Yaqui Ridge Trail provides hiker-only access as it descends steeply to the international border. From Montezuma Pass the route follows the Crest Trail (#103) up into the Miller Peak Wilderness. After a steep and strenuous ascent, it passes a junction with the Lutz Trail and soon reaches the turnoff to Miller Peak. From here the trail follows a ridgeline over to Tub Spring and then goes left at the signed Miller Canyon/Crest Trail junction and left again at the Carr Peak/Crest Trail junction. The trail continues on past the Oversite Canyon Trail junction, past Bear Saddle and Granite Peak, and then goes left at the signed junction with the Sunnyside Canyon Trail near Pat Scott Peak. It follows this trail down into Sunnyside Canyon, passes the Copper Glance Trail junction, and runs downstream to the wilderness boundary. Here it joins a dirt road (FR 204) for a short distance and then turns right at the AZT sign onto a trail again. It crosses FR 228 and then turns south into Scotia Canyon and works its way down to FR 48. After crossing this road the trail turns west and reaches the Parker Canyon Lake Trailhead on FR 194.
