Beautiful scenery, cool lakes, steep hills and tight turns; old school mountain biking at its best!

Please note that in 2018, the trails in the north area of the park will be undergoing a major redesign and reconstruction, so there may be large parts of the trail temporarily closed while construction is taking place.


An awesome combination of machine and hand-built trail, technical features, small hills, beautiful lakes and creeks!

This is a rapidly evolving trail system. There is currently a 13-mile loop that includes significant sections of newly built trail, some harescramble trail repurposed for mountain biking, and some older blast trail. It rides surprisingly well, and definitely has an "old school" feel to it.

The newer sections of trail flow very nicely. The new trail will continue to be built and will be replacing the older trail sections in a piecemeal fashion.


At the trailhead, you'll go through the gate in the fencing, head to the right and the entrance to the trail system is clearly marked.

The first part of the trail parallels 90th street and rides fast, eventually heading down a bermed descent, then heads back up through some berms and rollers. After this, you'll be riding on a doubletrack section that goes over a wooden bridge, keep your eye out for other trail users here as this is two-way trail, also shared with the Wright County hiking trail. After this, you'll emerge into a prairie and start riding some newer trail built late 2014, which eventually winds around "bald hill" giving great views when the leaves are down. At the end of this section, you have a choice to ride an optional loop that returns you near the bridge crossing, and you can cross the bridge to continue riding the return trail all the way back to the trailhead. There are some fun and rather significant trail features on optional lines throughout this return trail.

The trail then turns flat, twisty and fast for a while, bringing you to the "creek trail" section, which follows along a creek, crosses a bridge, and winds back on the other side, this trail is a local favorite and is quite scenic. The trail continues around the lakes, with a mixture of older and newer built trail. This area tends to change character frequently, but generally has good flow with great scenery.

There is also a small loop across the dirt road from the trailhead parking lot; simply ride directly across the road and there will be wayfinding posts marking the entrance. This is a self-contained 2 mile loop, which has great flow to it, and also has the large "Huck Harbor" trail feature on it.

The trail tread at this park is much loamier and softer than nearby trails, combined with the deeper woods this gives it more of a "rugged" feel in comparison. It also drains exceptionally well and is often ready to ride earlier than nearby trails after a rain event. If you are looking for a more rugged ride, this is the trail for you. Many people enjoy bringing their fatbike here. Winter riding is allowed (please stay off XC ski trails!), and a volunteer occasionally grooms the trail.
