The Ice Age Trail is a partnership park. The trail was authorized by Congress on October 3, 1980, as a component of the National Trails System and assigned to the Secretary of the Interior for administration.
Most of the work of building and maintaining the trail is carried out by Volunteers. The National Park Service administers the trail in cooperation with many Partners, leading the efforts to plan the permanent route for the trail. The National Park Service also provides technical and financial support to partners.

The trail links together six of the nine units of the reserve. The National Park Service manages property within the Cross Plains Unit of the reserve..
