Wilderness Landscape & Natural Heritage
Union Hills Wildlife Area is a 2,267-acre protected parcel located in Yuma County in northeastern Colorado. Characterized by its flat to gently rolling prairie terrain, the area encompasses a mix of native grasslands, wetlands, and agricultural fields that provide critical habitats for a diverse array of wildlife species. Historically used for hunting and wildlife management, Union Hills is recognized for its populations of mule deer, pronghorn antelope, upland game birds such as pheasants and grouse, as well as numerous waterfowl species during migration periods. The area is managed by Colorado Parks and Wildlife focusing on habitat conservation and regulated hunting opportunities. Outdoor enthusiasts come for birdwatching, hunting during designated seasons, and wildlife photography, appreciating the peacefulness of this relatively undisturbed landscape. Unlike large national parks, Union Hills offers a quiet, low-traffic experience where visitors can engage with prairie ecosystems rarely found in such protected status. Winter transforms the area into a stark but beautiful open range, while spring and summer bring wildflowers, migratory birds, and active wildlife. Access is generally through county roads with basic visitor amenities minimal, making it popular among those seeking off-the-beaten-path outdoor opportunities.
