U.S. Highway 12: Black River Falls to Hudson is a 120 mile trail located near Menomonie, WI. The trail is primarily used for scenic driving and is accessible year-round.
It has been a few years, but I remeber this pleasant road trip.
From seaplanes to scenery to towns with beautiful names it is a nice ride. I have only done this one in the summer, so I would love to do it in the winter. I know I love Southern Wisconcin in the winter.
