Plumb Lake Mountain Bike Trail
Plumb Lake Mountain Bike Trail is a machine-built, bike-only singletrack located within Plum Lake County Park in Sturgis, Michigan. Designed for beginner to intermediate riders, the trail spans just under 5 miles and winds along the scenic shoreline of Stewart Lake. Direction of travel alternates depending on the day of the week, so check signage before you ride. Class 1 eBikes are permitted.
While technical features are minimal, riders will enjoy rock-armored gully crossings, flowing berms, and smooth, bike-optimized terrain that allows for consistent momentum and a fun, fast-paced ride. Two multi-use boardwalks lead into the far northwest corner of the park, crossing a wetland area and adding variety to the experience.
The trail occasionally intersects with hiking paths, so please yield appropriately and be respectful of other park visitors.
