Hours & seasons
The Ice Age National Scenic Trail is not your 'typical' park. The trail is almost 1,200 miles long and crosses the state of Wisconsin north to south and east to west. The Trail is open year round. 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.
