Length:  15.7 miles

Southern Trailhead:  Italian Trap
- GPS Coordinates:  32.28317° N, 110.56849° W  
- Access: From Tucson, head east on Tanque Verde Road, which becomes Redington Pass Road after you leave the city. The road turns to dirt near mile marker 3. From that point, continue to just past mile marker 12 on Redington Pass Road. At the top of a small ridge, passenger vehicles should park on the right, as the remainder of the route is very rocky and bumpy. The AZT crosses Redington Road here. There are AZT signs on both sides of the road. Those who wish to reach Italian Trap by high-clearance four-wheel-drive may descend the other side of the ridge to the south and continue 2 miles. Park at a large, metal AZT sign near the corrals and fences. The last stretch of Passage 9 arrives on the road from the east.

Northern Trailhead:  Gordon Hirabayashi Campground
- GPS Coordinates:  32.33581° N, 110.71972° W
- Access: 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.

Trail Route Description:  From the Arizona Trail sign at Italian Trap the trail climbs steadily, turns to the west and then drops down to Redington Road. From here the trail heads northeast, then turns west and then reaches the Bellota Ranch Road. Just beyond the road crossing is The Lake Trailhead. From here the route follows the Bellota Trail (#15).

After passing around the Molino Basin Campground the trail climbs steadily westward until it reaches the Gordon Hirabayashi Trailhead.
