Directions:   Trail entrance from two main locations. 1) Off Woodland Ave. (there is a sign on the left about 2 miles past UMD) and 2) off of Hartley Pl. road (a left turn behind UMD from Arrowhead road)

Trail Information:   A nice mix of cross country ski trails and winding moderately hilly single track. Often fairly sloppy in parts so be ready for a little mud. A total of about 12k of trail with several loops for longer runs.
