O W Ranch begins off the Young Highway, running northeastward to the historic and still operating O W Ranch, where it deadends with a small turnaround. The trail's eastern end runs along Valentine Ridge along a shelf road with blind switchbacks.
The trail descends in the east to parallel the picturesque gurgling Canyon Creek, a destination for anglers in search of the stream's stocked trout. All fishing is catch-and-release. The stream is lined with open meadows, willows, and cottonwoods.
Dispersed campsites are located near the trail's intersection with Valentine Canyon. To minimize impact on Canyon Creek, camping is not permitted on the easternmost two miles of the trail. Valentine Ridge Campground is located midway along the trail. It is free and has shaded sites with picnic tables and fire pits/grills. However, there are no toilet facilities or water at the campground.
