Voted Best Place for Outdoor Fun since 2018

Philip S. Miller Park is a regional destination that truly has something for everyone. The 300-acre park includes the Millhouse events Graphic reads 2022 Winners - Macaroni KID Douglas County Family Spotlight Awards 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.

Construction update

  1. Sidewalk loop completion at the Philip S. Miller Park Adventure Playground - Two-track up to Epic Sky Trek

    We've added a sidewalk to provide an accessible looped connection between the parking area, aerial trekking course and adventure playground. Additionally, trail access to the red loop has been rerouted. The portable restrooms have been removed from the parking lot and relocated to a cement foundation located near the new paved trail to improve safety and free up seven spaces for parking. Curb and gutter has been installed on the far end of the parking lot and the trailhead has been relocated and formalized to improve access to park trails. Three new play features are being added along the new route, expanding the play experience at the adventure playground. 

    The project has been funded through lease fees paid by the Edge Ziplines and Adventures. Construction commenced the last week of April 2022 and the remaining new playground features will be installed in spring 2023.
