I have ridden this on both a cross bike and a mountain bike. It's a jeep trail, but not the kind you'd want to attempt in a car.
At the south end, go one mile past the corner of Sunshine Valley Road
and Mountain Road then turn north. You can park there or drive farther. Leave gates as you find them. Bear to the left and angle northwest. You'll come to a sign with directions. The closer you get to Ute Mountain, the steeper the trail becomes.
