Elroy-Sparta State Trail

This rail trail is 34 miles of Wisconsin natural beauty. People love to ride their bikes on it and the three hand-dug tunnels carved out in the late 1800s are part of the draw. Because the trail is so long there are plenty of built-in rest stops at the endpoint towns. If you're not up to a 34-mile challenge, you can catch the trail at Norwalk, Wilton, or Kendall. The trail is open year-round from 6 AM to 11 PM. If you're 16 or older, you'll have to buy a state trail pass before embarking on your adventure.
