The Colorow trail, named for the Ute Chief Colorow, makes a loop of approximately three miles through BLM land.
There are two trailheads, with a roughly laid-out trail through town connecting them. One trailhead is on Lariat Loop, in the northwest corner of Castle Valley Ranch. Hike up to the water tower and find the trail behind it. To reach the other, take North Wild Horse Drive to Buckskin Circle, then turn onto Mustang Trail.
Don’t miss the overlook turnoff on the eastern side of the trail. The short spur opens up to a panoramic view of Lakota Canyon Ranch and the hills beyond.
Most of the trail is not too difficult, though there are some challenging sections. It was constructed by the Roaring Fork Outdoor Volunteers, including members of the New Castle community (pictured right), and is co-managed by the Town of New Castle and BLM.
The Colorow trail is closed from December 1 through March 31 in order to protect the resident elk herd.
