Celebrate the 40th anniversary of the Ice Age Trail becoming a National Scenic Trail by joining the Mammoth Hike Challenge! Hike 40 miles on the Ice Age Trail during the month of October and visit three of our Trail Communities to earn a hiking certificate and a limited-edition patch celebrating the 40th anniversary. You may hike, walk, run, or backpack - whatever suits your lifestyle - and log your miles over days, weekends, weeks, or one big adventure. You have the entire month of October to do it! All abilities. All ages. All welcome. The Ice Age Trail traverses the entire state of Wisconsin and showcases its natural beauty and glacial landscapes. The Trail winds its way through 142 communities; 13 of them have chosen to become official Ice Age Trail Communities. It's a way for them to show their support for the Trail and to recognize Trail users as important players in their local economies. Trail Communities range from small roadside stops to bustling metropolises. They are a vibrant aspect of the Ice Age Trail hiking experience. Come explore them! More details at the link below.
