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. 

Place for community celebration

Philip S. Miller Park has proven to be an invaluable community asset through the many family friendly events it hosts. From the free concert series, to the offerings of the Millhouse event center and outdoor Amphitheater – in which 60+ annual weddings, graduations, reunions, celebrations of life, corporate meetings, ultramarathons, cycling races and more take place – the park serves as a true hub for community celebration. The Amphitheater and Millhouse also include the events pavilion, stunning pond and water feature, accessible concrete trails, additional parking and scenic landscaping.

Trails and amenities

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 shinning 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 Core Plaza, which houses picnic pavilions, restrooms, a splash pad, plaza area, outdoor fireplace, play features and landscaping. 

Core Plaza Pavilions and Splash Pad

The pavilions at Philip S. Miller Park (PDF) are the perfect location for your next get together. The four pavilions are located within the Plaza, which also houses a splash pad area, a community fire pit area area featuring the legacy brick program and a public art sculpture.  

There is one large pavilion next to the splash pad area that boasts six picnic tables under the pavilion and six uncovered tables, which together, can accommodate approximately 120 people. This pavilion also overlooks a grassy area perfect for yard games or relaxing with friends and family.

Additionally, there are three pavilions located west of the restroom building and north of the synthetic-turf field. The lower pavilion hosts two outdoor fireplaces that are activated by a timer. The two lower pavilions have eight picnic tables each and can accommodate approximately 80 people each plus wall seating. The third upper pavilion has six tables and can accommodate approximately 60 people each plus wall seating.

The Miller Activity Complex (MAC)

The MAC boasts an impressive indoor aquatics center with four lap lanes, a winding water slide, a zero-entry section with smaller slide, water table and a vortex whirlpool that simulates rushing currents of water. Adults and kids alike can also take a swing at the plate in the indoor batting cages. The MAC also features an indoor full-zed and half-sized synthetic field, trampoline beds and a children’s play structure.

Adventure components

Residents and nonresidents alike enjoy the park’s adventure components. Nearly 80 percent of The EDGE: Zipline Tours' revenue comes from those who live outside Castle Rock. The privately managed operation features a zip line course with 10 lines stretched throughout the park’s ridgelines; the Epic Adventure Tower allows users to scale a 40-foot climbing wall, zip and jump from a 40-foot platform or choose to freefall from a 70-foot platform while protected by state-of-the-art auto belay devices; and the Epic Sky Trek, an amazing three level challenge course includes 110+ elements that moves through green, blue and black challenges, including Ninja Warrior elements.
