This 5.5-mile (8.8 km) loop trail usually takes around 2 hours and 30 minutes to complete, depending on your pace and how often you stop to enjoy the scenery.
The trail offers diverse terrain. The West Ridge section involves gradual ascents and undulating ground, with some rugged parts due to exposed tree roots and occasional steep sections. The Karl Knapp Trail, in contrast, is largely level as it follows Prairie Creek. Be prepared for potential stream crossings that might require wading during winter months when a seasonal footbridge is removed.
