More than 12,000 years ago, an immense flow of glacial ice sculpted a landscape of remarkable beauty across Wisconsin. As the colossal glacier retreated, it left behind a variety of unique landscape features. These Ice Age remnants are now considered among the world's finest examples of how continental glaciation sculpts our planet.

The Ice Age National Scenic Trail is a thousand-mile footpath — entirely within Wisconsin — that highlights these Ice Age landscape features while providing access to some of the state's most beautiful natural areas.

The Ice Age Trail Alliance (formerly Ice Age Park & Trail Foundation), a volunteer- and member-based non-profit organization, protects, promotes, builds and maintains the Ice Age Trail. Ice Age Trail Alliance staff and volunteers work cooperatively with the Wisconsin Department of Natural Resources, National Park Service, local governments, businesses and private landowners to shape the Ice Age Trail into one of the premier hiking trails in the United States. Your support as a new member, volunteer or sponsor is always very welcome.
