To hike the Monticello Segment of the Ice Age National Scenic Trail, I parked at the Old Train Depot on Pratt Road in Monticello, WI. The parking lot is large with restrooms and refurbished buildings, all currently closed for the season. The Ice Age Trail (IAT) is not yellow-blazed on this segment, but the multi-use trails it follows are easy to find and follow. Heading north, I crossed County Highway C, and transitioned from the Sugar River Trail to the Badger State Trail. Not switching to the Badger State trail would have resulted in a walk to New Glarus rather than a walk through the Stewart Tunnel.
