About an hour south of Denver along Highway 285, Kenosha Pass is an easily accessible mountain pass with an elevation of exactly 10,000 ft. The pass is heavily trafficked by hikers, mountain bikers, and horseback riders along the Colorado Trail and has made many appearances in literature and pop culture.
Notably, references to the pass have been made by the poet Walt Whitman, author Thomas Pynchon, and the Comedy Central TV show “South Park”.
History

Before European settlers, Kenosha Pass was often used by Ute Indians headed toward hunting grounds near modern-day Fairplay, Colorado. During the gold rush, the pass was traversed by prospectors hoping to find gold in the same area. In 1879, the Colorado Silver Boom began and the trail over Kenosha Pass was widened to accommodate wagons heading west.
In 1879, the Denver, South Park and Pacific Railroad was completed, allowing massive amounts of materials and ore to be transported to and from the South Park mining communities. The original tracks were eventually dismantled in 1938. Today, US 285 follows the same route where the railroad was built over Kenosha Pass.

Compared to other passes, Kenosha is one of the most easily accessible. US Highway 285 is a well-maintained, paved road that is full of gentle curves and grades. Although it is slightly more challenging on the western side, most passenger vehicles can easily traverse Kenosha Pass.
At the summit of the pass, there are large, often-crowded parking areas on both sides of the road. There are bathrooms located near the campgrounds, but there is no running water. Just past the Kenosha Pass heading west, there is another parking lot with an overlook of the sweeping South Park area.
