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!
Runners and hikers, if you want to try an awesome 3-mile section, start under the west end of the Hell Creek bridge, and do the Hell Creek loop. Any of the remainder of the trail system is also great for running or hiking. Just remember that bikes go clockwise and foot traffic goes counterclockwise. Watch out for trail user traffic, and be very cautious making the 4 pavement crossings within the park.
This trail has some technically difficult sections in all the loops (except EZ). Most of the trail is moderate to easy, but there are several rocky sections, deep sand, arduous climbs, highly exposed ledges, and steep drops. On average, the trail is rated blue (intermediate riders), but there are black (expert only) sections interspersed, and an ample amount of green (any rider).
The trail is open year-around, spring and fall are best, but there are many great days for riding in the winter and early mornings are spectacular for riding in the summer months. Many sections of the trail are very close to the lake shore, which can make for a refreshing stop during the summer. There is no drinking water or restroom on the trail, except at the Trailhead. All park restrooms have showers, but are closed October-March. Cell phone coverage is about 75%.
Short cutting the trail will almost certainly result in exposure to poison ivy, which can cause an allergic reaction even in winter. If you stay on the trail, you need not worry about poison ivy. Pets are allowed on the trail but must be under control at all times. If you encounter a maintenance issue on the trail that needs attention, please call the trail coordinator.
If you want to observe natural beauty amongst the rust-colored Cretaceous Dakota Sandstone cliffs and outcrops, this trail is the place. The park was created from former grazing land and on this trail you’ll see many limestone fence posts that are historical remnants of the early ranching era of this land. Furthermore, private land just outside the park is still actively used for cattle ranching. Southshore Drive meanders through spectacularly scenic native rangeland and a favorite of local motorcycle tourists.
Watch out for wildlife in the summer, particularly herptiles on the trail – the ornate box turtle, horned lizard, racerunner, skink, legless lizard, collared lizard, and several species of snakes are all common during warm weather. Rattlesnakes are present in the park, most are a petite species known as the massasauga or pigmy rattler. It is unlawful to harass, kill, or injure wildlife in the park. Take care not to run over any critters on the trail.
You might also see wild turkey, deer, bobwhite quail, pheasant, red-tailed hawk, and many species of grassland songbirds such as larks and sparrows. The wildflowers and grasses are a spectacular part of the park’s natural landscape. Every season is different. Wildflowers show a constant progression of colors from early spring to late fall. Winter colors are vibrant rusts, browns, and golds set against the blue water of the lake. The Switchgrass Trail is named after a native prairie grass that is common throughout the central and eastern plains. Switchgrass grows abundantly in the park and has gained national attention as a prospective source of cellulosic ethanol.
