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.
