Green Trails

Baby Bella (Green, 0.3 miles)

Short, sweet, and wildly popular, Baby Bella cuts straight through the middle of Puffball and delivers quick access to Chaga, Sweet Tooth, and Shaggy Mane. jumps and berms suitable for beginner to intermediate riders.

Parasol (Green, 0.7 miles)

Parasol is smooth, curvy, and welcoming—perfect for beginners or anyone looking to warm up the legs. This friendly loop sets the tone before heading toward Lost Morel and the eastern trails of the park.

PUFFBALL TRAIL (GREEN, 2.9 MILES)

This curving single-track trail can be accessed from the Hunter’s East Parking lot off 770th Avenue. The trail is relatively easy and winds through prairies, pine plantations and open hardwood forests. It follows the contours of the Kinnickinnic bluff and provides scenic views of the Kinnickinnic River valley. The trail features several benches to enjoy the landscape.

Blue Trails

Abalone (Blue, 1.5 miles) - Spring 2026 Completion

Abalone dances across open prairie, ducking in and out of the woods just enough to keep you guessing. Features a high concentration of berms and rollers that encourage rhythm and flow.

Angel Wing (Blue, 0.7 Miles)

This trail serves as a fun connector to Slippery Jack and the other trails in the eastern portion of the system. The return portion to Dryad’s Saddle includes a tight switchback climb that will be sure to assess your technical skills.

Chaga (Blue, 0.8 miles)

Chaga is smooth, fun, and full of personality. Enter from Puffball and cruise past an abandoned car that looks like it escaped from a Bonnie and Clyde getaway. On the return trip, slow down just enough to soak in sweeping views of the Kinnickinnic River valley and roll over two short bridges that add a little flair.

Crimini (Blue, 0.7 Miles)

Crimini is a short, fun flow trail that passes through an area of the park that was harvested for aspen trees. It is home to “the Lost Pyramid of Crimini,” a seven-foot-high mound of dirt that you can ride over. Access to this trail is from either Skullcap or Slippery Jack.

DRYAD’S SADDLE (BLUE, 1.4 MILES)

This curvy single-track begins where the Lost Morel turns up the valley. Dryad’s Saddle climbs the opposite side through a wooded hillside, topping out in an open meadow before dropping through a series of bermed switchbacks into the valley and rejoining the Lost Morel trail.

LOST MOREL TRAIL (BLUE, 1.1 MILES)

The Lost Morel Trail can be reached from the Puffball Trail. The trail originates in an upland forest and quickly drops into a deep valley. This single-track trail winds its way to the valley bottom before beginning the challenging climb up the same side of the valley, ending back on the Puffball Trail.

Slippery Jack (Blue, 1.9 Miles)

Experience the perfect blend of drops, jumps and rollers on this fast-flowing single track. After a short climb, this trail winds through a variety of terrain along the east prairie of the park, dipping in and out of shallow ravines. It also supplies access to Skullcap and Crimini trails.

Sweet Tooth (Blue, 1.5 miles)

Sweet Tooth lives up to its name. Expect mellow climbs through shady pine stands followed by deliciously flowy downhills. Tucked inside the Puffball loop and accessible from Puffball or Baby Bella.

Black Trails

EMS (Black, 0.1 Miles)

EMS is the only trail in the network that is not named after a mushroom. Its primary purpose is to allow equipment access to the eastern half of the trail system. However, it makes a great alternate route if you want to test your legs on a curvy uphill climb.

MAITAKI MAYHEM (BLACK, 0.2 MILES)

This short alternate trail gives bikers the option to drop off the easy flow of the Puffball Trail into the fun and fast Maitaki Mayhem.

Shaggy Mane (Black, 0.6 miles)

A high-speed, advanced trail accessed from the end of Chaga. Shaggy Mane traverses a wooded hillside with old-growth hardwoods and pines, featuring small drops and jumps. The trail turns right and follows the Kinnickinnic River bluff before reconnecting with Puffball. Advanced skills and speed control required.

Skullcap (Black, 1.5 Miles)

Skullcap is rated the most difficult. It starts with a rock drop into a roller-coaster downhill, then proceeds past a scenic rock bluff and climbs to the top of the second downhill. The trail then meanders along the south ridge of the Kinnickinnic River valley before heading back to Slippery Jack or Crimini. Along the way, you will encounter a very steep and short climb that adds to the 225 feet of total elevation gain for this trail.

Stinkhorn (Black, 0.3 miles) - Spring 2026 Completion

A short technical ravine run threads through the bottom of one of the park’s many valleys and offers a rugged, challenging alternative route to Dryad’s Saddle.
