This highly scenic property is located along Park County Road 77 and abuts the Pike National Forest. In addition to its scenic values, Allen Creek Ranch contains over 3 miles of Tarryall Creek and supports one of the best examples of a globally rare riparian community comprised of blue spruce and water birch. The Ranch also contains mixed conifer forest, grassland, willow thickets, and irrigated hay meadows. The conservation easement also protects water rights that are used to irrigate hay meadows and Tarryall Farms. Allen Creek Ranch is now open to public fishing, on a reservation basis, at South Park Fly Fishers.
Funding for the Allen Creek Ranch conservation easement was provided by Great Outdoors Colorado, the Park County Land & Water Trust Fund, Colorado Division of Wildlife, National Fish & Wildlife Foundation, and the Hillsdale Fund, Inc.
