Mostly crushed gravel 10ft wide trail running through multiple forest preserves. There is some intermediate single track that will occasionally branch off the trail. The single track offers some tight corners, plenty of mud after rains, and quite a few logs. The single track is not supposed to be there... Near Old School Forest Preserve there is a sled hill that you can go down. This is south of Rockland Rd and north of Rt. 60.
How to get there:
Once in Libertyville you can gain trail access by taking 21(Milwaukee Ave) which parallels the river. Common access points are Rockland Rd. and rt. 60.
Nice ride in the fall. Very common to see deer along side of trail the further south you go.
