In June of 1993, the 400 State Trail was officially opened. It was developed on an abandoned Chicago-Northwestern Railroad bed that ran  between Chicago and the Twin Cities. The 400 Trail was named for the Chicago - Northwestern passenger train that traveled the 400 miles between Chicago and Minneapolis/St. Paul in 400 minutes.

  The 400 State Trail is located between Reedsburg and Elroy with 5 communities conveniently spaced.  The spur from Union Center runs southwesterly for 4 miles to Hillsboro.  The Trail Headquarters is located in the historic depot in Reedsburg.  

   The Baraboo River runs the entire length of the Trail, and the trail crosses the Baraboo River eleven  times in the 22  miles from Elroy to .  There is also a 7 mile horse trail between Wonewoc and La Valle which parallels the main trail.  The trail runs past wetlands, sandstone bluffs, farmland and pastures.

The 400 State Trail is part of a 100+ mile linking trail system.
