South Rim, Willow Creek, and Fountain Valley Loop

This loop is generally considered moderate. While sections like the Fountain Valley and Willow Creek trails are easier, the South Rim trail involves a significant portion of the elevation gain, which can be challenging, especially if you're not acclimated to the altitude.

The full loop, covering approximately 10.2 kilometers (6.3 miles), typically takes around 2 hours and 55 minutes to complete. This duration can vary based on your pace and how often you stop to enjoy the views.

This loop can be hiked year-round. Spring and fall offer pleasant temperatures and beautiful scenery, especially with fall foliage along Willow Creek. In winter, shaded areas can become icy, so microspikes or traction devices are recommended, particularly on the South Rim Trail.

Hikers frequently spot deer in the open meadows, and occasionally moose. Various bird species and smaller mammals are also common, as Roxborough State Park is recognized as an Important Bird Area by the Audubon Society.

Yes, the loop offers several excellent viewpoints. You'll pass by the Geology Overlook, Fountain Valley View, and Lyons Overlook. The South Rim Trail provides some of the best vantage points for photography of the park's unique red rock formations and distant views towards Denver.

The loop typically starts and ends near the Roxborough State Park Visitor Center, where ample parking is available. It's advisable to arrive early, especially on weekends, as the park can get busy.

If you prefer to get most of the elevation gain out of the way early, consider hiking the South Rim portion of the loop counterclockwise. This approach tackles the steeper climbs at the beginning of that section.

The Fountain Valley Trail, which makes up a significant portion of this loop, is generally considered an easy trail. It's mostly flat and weaves directly among the red sandstone formations, making it suitable for children, visitors not accustomed to altitude, or those seeking a leisurely walk.
