Located south of Tucson in the rugged Santa Rita Mountains, the Elephant Head Mountain Bike Trail is a great winter ride combining singletrack and jeep roads. The route starts from the lushly forested Madera Canyon along the old Proctor Road and winds through the Chino canyon basin and Agua Caliente canyon passing by an enormous butte (a.k.a. Elephant Head). At the five mile point, either turn around to enjoy that 3.5 miles of singletrack again, or press on via jeep roads up to the summit with the radio towers at the 12 mile point (3000' elevation gain).
To reach the trailhead from Tucson, follow US19 south for 25 miles to the Continental exit. Head east on Madera Canyon Road for 11 miles. Park in the lot just before the Proctor Ranch Road turnoff. Then follow the trail signs. When done riding, make sure to finish the drive up Madera Canyon Road into the lush forest under the shadow of Mt. Wrightson.
Keep an eye out for jaguars, which have been reported in this area.
