The Challenge Hill at Philip S. Miller Park continues to be a very popular amenity with over 230,000 visits each year. The Town does not currently have plans to construct another incline. If you’re looking for a new challenge, check out the Rosie Rueter Trail and Incline at Rueter-Hess Reservoir just 15 minutes north of Castle Rock. The reservoir’s incline was partially funded by the Town for the benefit and enjoyment of Castle Rock residents.
