Kent County Ramble is a 6.2 mile moderately trafficked loop trail located near Rockford, MI and is good for all skill levels. The trail is primarily used for road biking and is accessible from April until October.
Great trail. There's a smaller (yellow) loop and the larger (red) loop. The larger probably only being about 1 - 1.5 miles long. Lined with pine trees and pretty wide in most places. It also connects to a paved bike trail that goes a ways in either direction.
Very nice views, I only walked about 4 miles of the trails during some training but very scenic!
