After parking at the marked trailhead, take a left at the first fork and follow the double wide track until you come upon a second fork. Take a right at this fork to remain on the lower level trail which skirts the Upper Trinity Trail levee. You'll pass one ramp that goes up to upper trail; stay to the right and keep following lower trail until you see a second ramp. Take this ramp and follow the trail until coming to a mid-size open area and look for a jeep doubletrack to the right.
