Discover the Thrill of the Prairie Rock Trails

The Ultimate Guide to Mason City's New Mountain Biking Adventure

Prairie Rock Trails Bike Fest

Get ready for a weekend of dirt, fun, and community at Prairie Rock Trails Bike Fest, happening May 29th–31st at PRT Bike Park! Click HERE to learn more! 

You heard about new mountain bike trails in Mason City and now you want to check them out? Excellent! Here’s a guide as you begin your decent into being a crazy person that plays bikes in the trees for fun. If you’re already that person, then welcome – you’re among friends here.

A couple basics before getting too far. You’ll need a bike capable of riding on single track mountain bike trails – hardtail mountain bikes, full suspension and even fat tire bikes will all work. Can you ride these trails on your grandpa’s old 1960’s Schwinn? Sure, but you can also eat paint chips. Just because you can, doesn’t mean you should. You will also need a bicycle helmet no more than 3 to 5 years old. You get one brain, protect it. Equally important is to have hydration and carry your phone in case of emergency.

Now that we’ve covered the basics, let’s get to the main dish.

PRAIRIE ROCK TRAILS BIKE PARK

From a once-industrial landscape to a signature outdoor adventure hub, the Prairie Rock Trails Bike Park showcases how Mason City’s grit, creativity, and passion for outdoor recreation can transform a community. Designed and built by Rock Solid Trail Contracting, LLC—one of North America’s leading trail specialists—the Bike Park delivers a world-class riding experience right in the heart of North Iowa. Riders of all ages and skill levels will find something to love, with professionally crafted terrain that includes flowing lines, technical elements, a kid-friendly pump track, and progressive jump features. Whether you're learning the basics or chasing big air, the PRT Bike Park is built to inspire. Located at 1500 Elm Drive, adjacent to the Zerbles Trailhead.

TRAIL HIGHLIGHTS

The Rapids: Beginner-Friendly with a Thrill

Perfect for beginners with optional features like log/bridge skinnies, an extremely short loop that can be easily repeated, and a wide dirt path where the penalty for error is low. It also features an optional stairstep drop and a rock jump that can be easily ridden in either direction. The Rapids can be accessed from the Winnebago River kayak launch point off of 12th Street NE. If you’re feeling adventurous, try dropping in from the dead end on 10th Street NE.

Evans Preserve: A Playground for Advanced Riders

Cyclists describe this trail as an adult playground, which features seven progressive jump/tech lines. Each jump line is easily repeatable, and each progression offers new obstacles like table tops, knuckle jumps, and gap jumps. The two technical lines feature steep drops followed by rock garden navigation. The outer loop has a great cross-country feel, with many rollers and berms flowing through trees. The outer loop can be ridden in either direction. The inner loop from the eastern hub features a jump line with an optional stone drop and an observation point where you can rest. The inner loop is also easily repeatable. While the inner loop can be ridden in both directions, the preferred direction seems counterclockwise. Evans Preserve is excellent for intermediate to advanced riders.

Riverhawk: Flow through the Trees

A linear multi-directional trail with a great cross-country feel and flow through trees. (Hit at speed for an extra thrilling ride!) Jumps can be performed in several different areas, or you can simply roll over them. The trail is just under a mile long and has two access points. Enter from the west on Illinois Avenue near the Mason City High School softball field or the south on 4th Street by the Mason City High School parking lot.

Little Riverhawk: Built for Beginners

Little Riverhawk is excellent for beginners as the dirt trail is wide, and the penalty for failure is relatively low. It features a short square loop with many rollers that weave through trees along the south side of the property. It has dual inner pump tracks as well. The trail is located behind Lincoln Intermediate School on the large field at the corner of 18th Street SE and South Massachusetts Avenue.

SUGGESTED RIDE

For the best tour of the new trails, start at Zerbles Trailhead/City Dog Park parking lot. The future Mason City Bike Park is being constructed just north of this area!

  • From the parking lot, get on the River City Green Belt Trail (just south of the car wash off 12th Street NE) and head south along the Winnebago River.
  • Shortly you will come across The Rapids on your right. Continue south on the paved trail and follow the river as it turns east.
  • After going under a bridge but before East Park, turn north on the footbridge crossing the Winnebago River.
  • After going past the Mason City Aquatic Center, turn east on Birch Drive and continue until you cross a railroad track.
  • From the trail, you’ll see Evans Preserve to your left. Continue east on Birch Drive until you reach Illinois Avenue and then turn south, using the sidewalk on the east side of the road.
  • Almost immediately after crossing the bridge you will arrive at the west entrance of Riverhawk Trail on the left side.

Lime Creek Conservation Area: A Classic North Iowa Singletrack Experience

If you’re the kind of cross-country mountain biker who craves winding dirt singletrack, tight tree-dodging turns, roots, rocks, and a true “ride through the woods” adventure, Lime Creek Conservation Area is your go-to destination. This expansive natural area on Mason City’s north side has emerged as a cornerstone of the Prairie Rock Trails singletrack network, offering a mix of scenic bluffs, technical features, and beginner-friendly connections.

In recent years, Lime Creek staff and local partners have invested heavily in improving the trail experience—closing unsafe or unsanctioned paths, adding new connectors, installing official signage, and updating TrailForks to make navigation easier than ever. The result is a thoughtfully designed singletrack system that rewards exploration while still being friendly to riders new to the area.

Starting the Ride: From Zerbles Trailhead to Lime Creek

For the full Mason City XC singletrack experience, riders don’t actually begin inside Lime Creek. Instead, the recommended route starts at the Zerbles Trailhead next to the Prairie Rock Trails Bike Park. From here:

  • Riverside → Pumptrack → Brickyard offers a warm-up packed with features like A-frames, berms, rock drops, skinnies, and short punchy climbs. Session this area if you’d like—but for the complete experience, continue north.
  • Follow Zerbles Trail past the Calmus Creek Bridge to access an optional blue-rated gem: Highline. This segment includes a challenging climb and an unforgettable ride along a wooded bluff before delivering riders directly into Lime Creek.

Exploring Lime Creek’s Signature Trails

Once inside Lime Creek Conservation Area, the singletrack unfolds into a scenic, interconnected system:

  • Hackberry Trail: One of the most popular loops in the system, Hackberry offers repeatable laps and bluff-top views that showcase Lime Creek’s natural beauty. Need water or a quick break? Hackberry will lead you to the Conservation Center which offers a bottle refill station and bike aid tools.
  • Red Cedar Trail: Accessible via Lime Creek Road and Nature Center Road near the Conservation Center, Red Cedar delivers a little bit of everything—punchy climbs, rock gardens, and smooth hardpacked sections winding through stands of pines.
  • Wild Turkey Trail + Beaver Dam Option: The longest continuous trail in the area, Wild Turkey twists along ridges and bluffs before dropping into wooded terrain and ending near Quarry Lake. The optional Beaver Dam leg adds mileage and variety. Many riders choose to turn around at Quarry Lake and ride everything in reverse for a completely fresh feel.

Lime Creek also features miles of doubletrack—well-signed and easy to follow—perfect for extending your mileage, connecting loops, or exploring at a more relaxed pace.

Navigation & Rider Tips

Thanks to new trail markers throughout the conservation area and updated TrailForks data, navigating the Lime Creek Conservation Area has never been simpler. On TrailForks:

  • Blue = singletrack
  • Green = doubletrack

Checking the map online or through the TrailForks mobile app is highly recommended before you ride.


Visiting? Need a guide?

Lots of us are out riding the trails anyway, and quite a few of us are comfortable playing tour guide. Another good option is to join the Wayne’s weekly shop mountain bike ride. We often ride the city side and into Lime Creek Nature Center. That event is every Tuesday at 6:30 PM starting at Zerble’s Trailhead. >> RIDE WITH US
