Southern Trailhead: Gordon Hirabayashi Trailhead


Follow Tanque Verde Road east from Tucson and turn left (north) on the Catalina Highway. Drive about 9 miles and pass Molino Basin Campground. Continue 1.7 miles beyond the campground and take the left (west) turn to Gordon Hirabayashi Campground. Drive 0.3 miles to a parking area. Follow a trail out of the south end of the parking lot for 40 yards to reach a “T” intersection with the AZT.

Northern Trailhead: Oracle Ridge Trailhead


From Tucson, head north on Catalina Highway high into the Santa Catalina Mountains toward the town of Summerhaven. After passing Loma Linda Picnic Area and just before the road to Mt. Lemmon Ski Valley, turn northeast (right) on FR 38 (Mt. Lemmon Control Road). Pass the Fire Station on the east (right) side of the road and follow the dirt road a short distance downhill. Look for the trailhead for Oracle Ridge on the west (left) side of the road where there is space for a few passenger vehicles.

Trail Route Description

The Pusch Ridge Wilderness Bypass is an alternate route for trail users to avoid the designated wilderness area within Passage 11 (ideal for hikers, but illegal for mountain bikers and very dangerous for equestrians). The ATA strongly recommends this route for equestrians so they can avoid the difficult northern section of Passage 11 (Santa Catalina Mountains). This bypass is a very technical route, but safer than Passage 11 for equestrians.

From the Gordon Hirabayashi Trailhead the route crosses Catalina Highway and then follows Bug Springs Trail, Green Mountain Trail, Incinerator Ridge Trail, and then on the Butterfly Trail. It joins the Crystal Spring Trail which ends on the Control Road. This road takes you to the Oracle Ridge Trailhead and the end of the bypass.
