Considered the first rail-to-trail in the United States, the Elroy-Sparta State Trail is one of the most popular trails in the country. With three rock tunnels and five small towns along its 32.5-mile route, the trail is a favorite Wisconsin bicycling destination. Two small rustic campgrounds connect to each end of the trail in the communities of Elroy and Sparta.
