State Highway 125 is a state highway in the U.S. state of Colorado. The highway runs north–south through Jackson and Grand counties in north central Colorado. It furnishes the principal north–south link through North Park and a connection to Middle Park over Willow Creek Pass. It is two-lane along its entire route.

Route description

At the northern end, the highway begins at the Wyoming state line, where it is contiguous with Wyoming Highway 230. It follows the North Platte River and Michigan River southward through Cowdrey and Walden, the county seat of Jackson County and the largest community along the road. At Walden it intersects 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 (elevation 9621 ft), 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 two miles (3.2 km) west of Granby.
