At Walden it intersects Colorado [State Highway 14|State Highway 14]. South of Walden, it crosses the southern end of North Park along the valley of the Illinois River, a tributary of the Michigan. It passes the unincorporated community of Rand, then ascends into the mountains and crosses the continental divide at Willow Creek Pass, one of the lowest crossings of the continental divide in Colorado. On the south side of the pass it descends the sparsely populated valley of Willow Creek into Middle Park. It terminates at its southern end at U.S. [Highway 40 (Colorado)|U.S. Highway 40] two miles west of Granby.
