The Mammoth Hike Challenge is a completely free event created by the Ice Age Trail Alliance to promote and celebrate the beauty of this amazing trail that stretches all the way across the state of Wisconsin. During the month of October, simply track 41 miles of activity anywhere on the Ice Age Trail (hiking, walking, running, or backpacking), AND visit three of the Trail Communities.

The Ice Age National Scenic Trail is a thousand-mile footpath that highlights these landscape features as it travels through some of the state’s most beautiful natural areas. The Trail is entirely within Wisconsin and is one of only eleven National Scenic Trails.

St. Croix Falls, known as the “City of Trails”, is a proud Ice Age Trail Community and home of the Western Terminus of the trail.

We would be delighted if you would start right here in St. Croix Falls, WI! It makes a great start point (it is the Western Terminus of the trail) meaning the trail literally starts (or ends, depending on your route) right along the high bluffs of the St. Croix River inside Interstate Park, WI. If you hike the entire St. Croix Falls Segment, you’ll log 9 of your 41 miles right here. And, since St. Croix Falls is an official Trail Community, you’ll get a check in that challenge box too.
