This is a wonderful rural rail-to-trail which for the most part is out in the middle of nowhere. The town of Poplar Grove in the middle of the trail has a couple of stores where refreshments can be purchased.
Note that this trail has quite a few jarring bumps (actually depressions in the asphalt) so be careful when you ride it.
In a car, the eastern trail head can be reached by taking Route 173 west from Harvard. Turn right on County Line Road and go approximately a half mile to the parking lot on the left side of the road.
Want to bike to the trail? If you like paved rural roads and don't mind a couple of rolling hills the following route of just under 8 miles can be used to get to the trail head from the Metra station in Harvard: Turn right onto South Ayer Street. After a couple of blocks take the angle left onto South Morengo Road. Turn right at Airport Road. Go left on Flat Iron Road. Turn right onto Streit Road. Turn right onto County Line Road. The trail head will be on your left a half mile after you cross Route 173.
