Falling Waters Trail is a 21.7 mile moderately trafficked out and back trail located near Concord, MI that features a lake and is good for all skill levels. The trail is primarily used for walking, trail running, and road biking and is accessible year-round. Dogs are also able to use this trail but must be kept on leash.

If this is the Falling Waters Trail, it is a "rails to trails", paved bike trail, from Weatherwax Trail Head to Concord, MI. is close to 10 miles. If you begin in downtown Jackson, the trail could be close to 20 miles depending on your inter-city route and site seeing. I heard the Lime Lake Jackson County Park has a beach, and makes for a great day trip.

This trail is on my wishlist - 2015
This is a flat, straight paved rail trail. This site says it is 7.5 miles, but I believe it is much farther (upwards of 20?). There is some nice scenery, especially near the lake in Spring Arbor.
(There is also a marathon/half-marathon/5k here in October.)
