Trail Route Description:  From the Davidson Canyon-Gabe Zimmerman trailhead the trail drops down into Davidson Canyon, joins Cienega Creek, goes under the train trestle, and then climbs out of the canyon on the north side. After joining a two-track, the route turns sharply back to the southwest and then crosses Marsh Station Road. From here the trail heads west and then north across several drainages. It crosses a pipeline road and then goes under some powerlines. From here it climbs up to a saddle and a view of the La Posta Quemada ranch and the south end of Colossal Cave Mountain Park. The trail switchbacks down and then around the ranch to the east. It enters the park and parallels Posta Quemada Canyon past the campground and up to a park road. After crossing the road, it parallels it and then comes to the La Selvilla picnic area. From here it runs north-northwest up to Pistol Hill Road, crosses this road and then the X-9 Ranch Road, and continues up through the Rincon Valley. After passing through a gate the trail crosses Rincon Creek and then reaches a kiosk at the boundary of Saguaro National Park.
