Fourmile Creek flows through the rugged terrain of Teller and Fremont Counties in Colorado, originating in the high country west of Cripple Creek and descending eastward through a scenic canyon before joining the Arkansas River near Cañon City. This approximately 23-mile creek system drops through pinyon-juniper woodlands and ponderosa pine forests, carving a distinctive canyon that has attracted both recreational users and paleontologists over the decades.

The creek flows intermittently through much of the year, with reliable flows typically occurring during spring snowmelt (April through June) and after significant rainfall events. During peak runoff, Fourmile Creek can transform from a modest stream into a swift, debris-laden torrent unsuitable for watercraft. The creek's flow is heavily influenced by upstream diversions serving the historic mining communities of Cripple Creek and Victor, as well as municipal water needs, making it an unreliable paddling destination.

The Fourmile Creek corridor serves primarily as a hiking and mountain biking destination rather than a paddling venue. The BLM-managed lands along the creek provide approximately 10 miles of recreational trails, with the creek itself offering limited aquatic recreation opportunities. The trail system following the drainage includes sections like Mutton Bustin' and connects to the broader South Cañon Trails network, providing access to the canyon's geological and paleontological features.

Notable features along Fourmile Creek include exposures of the Dakota Hogback formation and Morrison Formation rocks that have yielded significant dinosaur fossils. The Garden Park Fossil Area, located near the creek's lower reaches, represents one of the most important Jurassic-age paleontological sites in North America, where Stegosaurus, Allosaurus, and other dinosaurs were first discovered in the 1870s.

Access to Fourmile Creek is available from multiple points along County Road 3 (Temple Canyon Road) west of Cañon City, with the Ecology Park serving as a primary trailhead. The historic Gold Belt Tour Scenic Byway (Shelf Road) crosses the upper watershed, providing additional access points near the Teller-Fremont county line.

Wildlife in the corridor includes mule deer, black bears, mountain lions, and various raptor species. Rattlesnakes are common in the lower elevations during warmer months, requiring caution for trail users. The riparian zone, though limited by intermittent flows, supports cottonwoods and willows where water persists.

Recreationists should note that Fourmile Creek is not suitable for paddling or floating due to insufficient flows, numerous diversions, private property concerns, and the presence of man-made structures. The drainage's recreational value lies in its trail system, geological features, and historical significance rather than as a waterway for boating activities.
