Hell Creek Loop in the Switchgrass Trails at Wilson Lake.
The Switchgrass trails in Wilson State Park were designed, built and are maintained by the Kansas Trails Council, Central Kansas Mountain Bike Club and their volunteers.
The mountain bike trail is a clockwise stacked loop system. It begins at the trailhead (go left at kiosk) in Switchgrass Campground with the Golden Belt Loop (aka, gold), then the Marina Loop (aka, purple), and finally the Hell Creek Loop (aka, red). If you wanted to ride all the loops in order, you’d ride Gold – Purple – Red – Purple – Gold. Begin at the trailhead on the Gold, then intersect with the Purple, then ride the Red. After completing the Red, you get back on the Purple. Completing that, you are back on the Gold. That’s about 22 miles all of which is great singletrack. If needed, the trail is never far from a bailout to a paved road back to the trailhead. Plan on 2-4 hrs depending on biking skill and how much sightseeing you might want to do. The loop record for racing is 1:40.
The novice level (EZ) loop is a 2-mi clockwise loop or 5-mi if you add the optional Bird Loop. EZ also starts and ends at the Switchgrass trailhead (go right at kiosk). It is non-technical with no climbs, no deep sand, and very few rocks. It is about a 20-40 minute ride suitable for beginners. But, EZ is a genuine mountain bike trail, so don’t expect a paved path!
