The Big M Route is aptly named for the huge “M” on the side of a mound outside of Platteville, WI. It is the largest “M” in the world! Take the time to stretch your legs and hike to the top for an amazing view!  Located in southwest Wisconsin, this route ranges from the Illinois border nearly all the way to the Wisconsin River. The geography varies from the high bluffs and deep valleys near the major rivers to the rolling farmland one expects of southern Wisconsin. Get ready to ride both small, tight, twistie roads and fast highways.  Because this part of Wisconsin contains some of the earliest settled land, there are a lot of historic sights throughout the entire region. There are many museums and exhibits describing the early life and industry in the area such as the Brewer museum in Potosi, the Mining Museum in Platteville, Shake Rag Alley in Mineral Point, and Wisconsin’s First State Capital in Belmont. In addition to these historic sights, this route also boasts access to 4 Wisconsin Rustic Roads (#s 66, 70, 75, 99).  So set your sights on the Big M Route, and bring your hiking shoes!
