This is an eastern plains unit that includes some bottomland along the Arkansas River north of La Junta. The land is mostly private although there are some state trust lands and several state wildlife areas.

Trophy quality whitetail and mule deer live along the Arkansas River and Horse Creek. A few pronghorns are scattered in the unit and elk are scarce and difficult to find. This is a heavily hunted unit.

Good county roads throughout the unit. State wildlife areas include Adobe Creek Reservoir, Fort Lyon, Holbrook Reservoir, Horse Creek Reservoir, Melon Valley, Oxbow and Rocky Ford. No hunting is allowed at Horse Creek Reservoir without permission of the grazing leaseholder. Dawn Pond State Wildlife Area is open to fishing only.

Short-grass prairie with limited farmland and cottonwoods in creek bottoms

Adobe Creek, Holbrook Reservoir, Horse Creek Reservoir and Rocky Ford state wildlife areas allow parking lot or primitive camping with a restroom. The closest town to most of Unit 125 is La Junta, which is along the southern boundary and provides all services. Try the Copper Kitchen or El Rincon for good Mexican food.
