The West Elk Loop Scenic and Historic Byway is a 205-mile (330 km) National Forest Scenic Byway and Colorado Scenic and Historic Byway located in Delta, Garfield, Gunnison, Montrose, and Pitkin counties Colorado, USA.

The byway reaches its zenith at Kebler Pass, elevation 10,007 feet (3,050 m), between Crested Butte and Paonia.

The route follows SH 133 south down the Crystal River Valley past Mount Sopris and Redstone to McClure Pass, with an official detour option to Marble.

[3] The true Loop portion of the Byway begins and ends below Paonia Reservoir and The Raggeds where Kebler Pass intersects SH 133.

From Crested Butte, one can only complete the full loop back to SH 133 in summer months, when unpaved Gunnison County Road 12 is plowed over Kebler Pass.
