36 acres to make your own on the Longhorn Ranch. Bring your RV, build a cabin or just enjoy the antelope and what nature has to offer at on your own private acreages. Plateaus and mesas for you to view in the southeast corner of Colorado. Las Animas County is one of the largest of Colorado's 64 counties and is located about 200 miles due south of the Denver Metro area. In my never-ending search for the perfect homestead I stumbled across Longhorn Ranch and a number of other rural communities throughout the county. Awesome things of Longhorn Ranch, and other areas around the county, are their relative remoteness, wide-open spaces and clear skies.
