Jack Lake Mountain Bike Trail in Langlade County's Veterans Memorial Park offers 12-miles of fast and flowing single and double-track mountain biking trails. Whether you're a first-time biker or a longtime shredder, these trails have something for everyone. In the winter, the trail is groomed for fat tire biking. The trail weaves its course through changing scenery of northern hardwood, aspen, and conifer forest types. The trail also meanders along three undeveloped glacier lakes, wetlands, and bogs.

Restrooms are available by campground showers when the campground is open.
