Philip S. Miller Park
Philip S. Miller Park is a regional destination that truly has something for everyone. The 300-acre park includes the Millhouse events center, an outdoor amphitheater, the Miller Activity Complex, the Challenge Hill outdoor staircase, an adventure playground and an interconnected trail network. Through a public-private partnership with The EDGE: Zipline Tours, ziplines and adventure courses are also available for play.
The 8-mile native-surface trail network consists of single-track trails divided into four different, but interconnected, loops. An additional 1 mile of paved accessible trail also circles the park. The trail’s shining jewel is the 200-step Challenge Hill. Rising 178-feet in elevation, it’s a lot tougher than it seems, but the views at the top are hard to beat.
The 2.5-acre Adventure Playground features a 40-foot long slide and many unique play options that blend seamlessly with the natural terrain, Gambel Oak and Ponderosa Pines. A full-size synthetic-turf field, concrete pathways, parking and lighting sit adjacent to the playground.
Next to the athletic-turf field sits The Plaza, which houses picnic pavilions, restrooms, a splash pad, plaza area, outdoor fireplace, play features and landscaping. The restrooms and outdoor fireplaces are operational from 7 a.m. to 10 p.m. daily. The splash pad is open from 10 a.m. to 6 p.m. seasonally.
Sidewalk loop completion at the Philip S. Miller Park Adventure Playground - Two-track up to Epic Sky Trek
The Town of Castle Rock is adding a sidewalk along the existing unpaved path that will provide an accessible looped connection between the parking area, aerial trekking course and adventure playground. Additionally the two trail access points at the end of the parking lot and by the Edge zipline will be temporarily closed as trail access to the red loop is rerouted. The portable restrooms will be relocated out of the parking lot to improve safety and free up seven spaces for parking as part of the project. Curb and gutter will be installed on the far end of the parking lot and the trailhead will be relocated and formalized to improve access to park trails. Three new play features will be added along the new route, expanding the play experience at the adventure playground.
The project is funded through lease fees paid by the Edge Ziplines and Adventures. Construction will commence the last week of April and is scheduled to be complete by summer 2022.
