This area provides a quick escape into forested open space from nearby Downtown Castle Rock. The 43-acre parcel is located south of South Ridge Elementary School and can be accessed from a paved trail at Oman Road. The willows and cattails in the riparian area quickly change to a mature ponderosa pine forest on the ridge’s north-facing slope. A short trip to the top of this ridge can provide views of the southern areas of Town.
