Largest Ranches in Colorado

5 Largest Ranches in Colorado

Cattle ranching in Colorado started in the early 1800s when Texan cowboys discovered the abundance of the grassy areas and began moving cattle into western Colorado. The migration is also closely aligned with the removal of Native American tribes onto reservations and the opening of the territory to white settlement.

Embracing the challenging terrain, the cattle and ranching industry in western Colorado continued to grow throughout the 1800s. The permanent abundance of highly nutritious grasses became the main driving factor for cattle ranchers.  

Until the 1930’s, all of the land used by cattle ranchers was open-range land and branding cows became common practice as a way to distinguish the herds that often intermixed as they freely roamed the mountainous areas. Eventually, the open-range era ended as well as the very common fall and spring round-ups.

Today Colorado ranching is primarily structured as a private range in the eastern plains and a federal range in the mountains and in lower desert ranges of western Colorado.
