More information
The Ice Age National Scenic Trail spans 1,200 miles, traverses some of Wisconsin's finest geologic and glacial features, and passes through the ancestral lands of 15 Tribes. The Trail is built, managed and maintained by dedicated volunteers, Ice Age Trail Alliance, Wisconsin Department of Natural Resources, local partners, and the National Park Service.
NP Tracker keeps a record of every National Park Service unit you visit — all 430-plus of them. Log visits with dates and photos, collect passport stamps, plan trips, and watch your map fill in. It's free.

However some segments may be closed during Wisconsin's November 9-day gun deer hunting season. Additional information about hunting seasons, trail conditions and closures along the rest of the trail is available from the Wisconsin Department of Natural Resources and the Ice Age Trail Alliance.
