Heil Valley Ranch is one of the newest of the Boulder Open Space Parks and, as such, is still a work in progress. The 4,923 acre park sits in the foothills north of town on rolling, rugged and heavily forested land. There are presently three multi-use trails open. The 2.5 mile Wapiti Trail runs north from the trailhead parking lot and gains about 800 feet in elevation. At its northern end, the Wapiti intersects with the Ponderosa Loop Trail, which is a very rocky ribbon of single track that twists and turns through the woods for 2.6 miles. Completed in the fall of 2007, the Wild Turkey Trail is another loop that takes off from the eastern side of the Ponderosa Loop and courses for 2.9 miles over moderately rocky terrain. All of these trails are rated intermediate, and are quite popular with mountain bikers, hikers and equestrians. In the summer of 2008 a new connector, the Picture Rock Trail, was built linking Heil Valley Ranch with Hall Ranch, located west of Lyons and just north of Hwy 7. The new trail creates a network of trails in both parks that extends for over fifteen miles.
