Elevenmile Canyon is managed by the USDA Forest Service to protect its rich natural resources and historic sites, and to provide public recreation. The focal point along this route is the South Platte River which begins high above Fairplay and flows in a southeasterly direction across South Park. Below Elevenmile Reservoir, the river turns northeast and cuts into the Pikes Peak batholith - a large mass of igneous rock. Originally called "Granite Canyon," the towering walls are composed of Pikes Peak granite that have been polished gray from years of weathering. In places the canyon rises dramatically 500 feet above the river.

Construction of the Colorado Midland Railway started in 1886 and ultimately spanned 261 miles between Colorado Springs and New Castle. The winding section through “Granite Canyon” was completed by April 1887. For thirty-two years the Midland hauled coal, livestock, hay, wool, lumber, produce, other goods, and passengers, before ending service in 1918. It is thought to be the largest abandoned rail project in the world.

The description and points of interest have been adapted from The Elevenmile Canyon Heritage Tour brochure produced by the Park County Tourism Office with editorial copy provided by Laura Jarrow, USDA Forest Service, Pike National Forest.

The road has not been officially designated as a state scenic byway.
