The 7.4 mile native-surface trail network consists of single-track trails divided into four different, but interconnected, loops with 1.2 miles of paved accessible segments in the active park area near the Miller Activity Complex, the MAC.  The trails explore all the valleys, knolls and high points of this 300-acre site.  A unique feature on the site is the Challenge Hill, with 200 timber steps that climb 178 feet in elevation, similar to the Manitou Springs Incline. Bikes are not recommended on the Challenge Hill.


Horses and ATV's are not allowed on the trails.
Dogs are not allowed on the Challenge Hill.
