In 1881, a railroad was put in place on the trading route. This railway connected to Chicago, Harvard, Caledonia, Beloit, Clinton, Madison, Lancaster, and other towns across Wisconsin. An advertisement for the Iron Horse Tour, which was a railway tour to the countryside for those who lived in Chicago, was for railfans, camera fans, nature lovers, and geologists.
After the Cave of the Mounds was open to the public in May 1940, a stop was added on the route for passengers to visit Cave of the Mounds. When they departed the train, the passengers would walk through the wooded area to where the Cave of the Mounds Entrance Building stood and waited in line until they could enter the cave.
By 1976, the condition of the track had deteriorated and was abandoned in 1979. On January 25, 1983, the Wisconsin DNR was approved for the purchase of the abandoned railroad and created a state trail. It was dedicated in Barneveld on May 19, 1985.
Today there is a diverting path off the Military Ridge Trail that leads directly to the Cave of the Mounds parking lot. There are racks to lock up bicycles for those biking along the pathway. This trail is open all year and we have been side by side for a very long time.
