Located immediately west of the Rueter-Hess Water Purification Facility (11865 Heirloom Pkwy, Parker CO), a parking lot has been designated for visitors at the trailhead of the Incline Challenge. Visitors should turn west off of Heirloom Parkway when they reach the Rueter-Hess Water Purification Facility, and continue west to the designated Incline parking area. The Incline features 132 steps and the Rosie Rueter Trail loop that leads to and from the parking lot is just over a mile long.
