Mica Mountain Trail Professional Review and Guide
"This is a backpack trip over the summit of the Rincon Mountains via two branches of the Arizona Trail. All the springs on this route are seasonal except Manning Camp Spring, and they dry up during the summer and fall dry seasons. Check with the Rincon Visitor Center before your trip to get the latest information on the springs and other water sources. Spring, after snowmelt, is a good time to do this trip as there will normally be plenty of water sources.
From the trailhead, the Miller Creek Trail (the route of the Utah-to-Mexico Arizona Trail) follows Miller Creek, a seasonal stream, west through the oak woodland in the Rincon Mountains foothills. After passing the Saguaro National Park boundary, the trail starts to climb the steep eastern slopes of the Rincon Mountains in a series of broad switchbacks. The trail is rocky and steep in places as it works its way through complex terrain with granite cliffs, large boulders, and chaparral brush. Pinyon pines and junipers start to appear as you climb, and the view of the wild country to the east expands."
