Trailhead Description

From the trailhead, there is access to several moderate trails: Doudy Draw, Community Ditch, Flatirons Vista Loop, Spring Brook Loop and Goshawk Ridge. This area was rich with mining and agriculture. In this dry landscape, irrigation is a necessity for providing water to hay fields and pasture land. The flow of South Boulder Creek was diverted by the construction of a series of ditches. Community Ditch, constructed in the early 1900s, was one of the last water diversion projects along the creek.

This area is closed when conditions are too muddy; please check the trail map for closures before visiting.
