Philip S. Miller Park

The wait is over! Castle Rock's largest park project ever is officially open for businesses. Construction on the adventurous regional park began in summer 2013. Now, the 300-acre Philip S. Miller Park truly has something for everyone.

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. The trail's shinning jewel is the 200-step Challenge Hill. It's a lot tougher than it seems, and has already been wildly popular with fitness buffs.

This active regional park includes a 2.5-acre Adventure Playground that features a 40-foot long slide and many other unique play options that blend seamlessly with the natural terrain, Gambel Oak and Ponderosa Pines. In addition, a large synthetic turf athletic field, concrete pathways, parking, lighting, the privately operated Castle Rock Zip Line Tours (a zip line course with 10 lines stretched throughout the park's ridgelines) and the privately operated Epic Adventure Tower (which 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 3 level challenge course including 110+ elements that moves through green, blue and black challenges, including the Ninja Warrior elements) rounds out the amenities which were all completed in this first phase. 

The MAC also 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 play video golf on a 18-hole simulator using real clubs and a life-size projection screen or take a swing at the plate in the indoor batting cages. 

The second phase of construction added 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 9 p.m. seasonally. Gas grills are allowed, however charcoal grills are not.  Please note, at times, Town fire restrictions may prohibit the use of grills. Visit the Town's fire restrictions page for more information.

The Amphitheater and Millhouse includes the events pavilion, outdoor amphitheater, pond and water feature, accessible concrete trails, additional parking and landscaping.

Starburst Award received for the Philip S. Miller Park Adventure Playground and Trail System Project!!

The Parks and Recreation Department will be receiving a Starburst Award from the Colorado Lottery for the Philip S. Miller Park Adventure Playground and trail system project. The award recognizes project excellence in the use of Lottery proceeds for community and conservation projects. Winners are chosen based on the creativity of the project, the economic and social impact on the community, and whether the project achieved its goal.

A local parks and recreation grant was awarded to the Town in 2013 from Great Outdoors Colorado, a Lottery beneficiary, for the construction of the playground and soft-surface trails at the park. The trails have been open since fall 2014 but construction of the playground was completed and opened for public use in spring 2015. Projects completed within the past three years using Lottery proceeds are eligible for this award from the Colorado Lottery. 

This will be the Town’s third Starburst Award recognition from the Colorado Lottery. Previous awards were for the Quarry Mesa acquisition in 2008 and the East Plum Creek Trail (phase four) in 2009. Castle Rock is among 19 other Colorado communities who received the award this year.
