Grassy, dirt doubletrack. Flowy with rolling hills throughout. Fun and not technically demanding for even the newest riders.
From Hwy 61 in Winona, Head north to the hidden valley turn. (Across from LaCanne Park) Turn and follow left up to hidden valley. At the entrance, there is a gravel road on the right. Ride the gravel to the top of the bluff, there is an intersection at the top. Go to the right and the plowline loop is about 100yds up.
