This is a great trail located near Mandan that circles Harmon Lake. The trail features beautiful wild flowers, native prairie grasses, and flowing, rolling hills. There are not any technical sections on the trail. More advanced riders can take this trail at a mid-high speed and with the smooth rises and descents and some tight corners, it can feel much like a roller coaster. The views and scenery are very attractive. The flow of the trail is better if ridden clockwise and the trail surface consists of dense packed dirt and some rock.
