This 300-acre park has something for everyone!

The Millhouse: A premier rental venue for special events with a stunning pond and water feature, accessible concrete trails, additional parking, and scenic landscaping.

The Amphitheater: Enjoy the gorgeous view of the hills and park from the Amphitheater. It is home to various events during the summer, such as free and paid concerts, fitness in the park, and other community events. 

The MAC: Home to a functional fitness area, full- and half-court turf field, indoor trampolines, climbing structure, and an impressive indoor aquatics center with four lap lanes, a winding water slide, a zero-entry section with a smaller slide and a water table for younger children, and a vortex whirlpool that simulates rushing currents of water.

FitGround: Completed in late 2019, the equipment is for ages 13 and up. It includes body-weight and free-form tools for resistance, plyometric, or cardio-based exercises. FitGround includes nets, a rope climb station, parallel and push-up/inverted row bars, balance steps, plyo-steps, a pull-up station, a sled, sit-up stations, fingerboard pull-ups, and dip bars.

2022 Family Spotlight Award Winner for Best Place for Outdoor Fun!
Also Won in 2018, 2019, 2020, AND 2021!

Adventure Playground: 2.5 acres of fun covers an entire hill. There is a domed rope climbing playset, a 40-foot-long slide that runs down the side of the hill, a playset with slides, a sand area, swings, teeter-totters, rope swings, and a saucer swing. 

Trail Network: The 8-mile native-surface trail network consists of single-track trails divided into four separate but interconnected loops. An additional mile of a paved accessible trail also circles the park.

Challenge Hill: The trail's shining jewel is the 200-step mini-incline Challenge Hill. Don't let the name fool you; the incline isn't so little — rising 178 feet in elevation — it's a lot tougher than it seems, but the views at the top are hard to beat. 

The Plaza: Houses picnic pavilions, restrooms, a splash pad (weather permitting), a plaza area, an outdoor fireplace, play features, and landscaping.
