The Gold Hill via Fourmile and Sunshine Canyons touring cycling route offers a dynamic experience through canyons and subalpine forests, culminating in the historic mining town of Gold Hill. You'll wind through diverse terrain, from paved sections to significant unpaved and dirt roads, enjoying panoramic vistas of the Rocky Mountains and glimpses of the Indian Peaks from Sunshine Canyon. This difficult 23.1 miles (37.2 km) loop, with its 3398 feet (1036 metres) of elevation gain, is a local favorite for its challenging ascents and rewarding descents.

The estimated duration is around 3 hours and 27 minutes, so pack enough water and snacks for a sustained effort.
What makes this route truly stand out is its blend of natural beauty and historical significance. The quaint, historic mining town of Gold Hill, largely preserved since 1859, provides a unique backdrop and a perfect spot to refuel at the Gold Hill General Store. This loop also serves as a gateway to more extensive adventures, with options to connect to other routes like the Switzerland Trail or the Peak-to-Peak Highway.
