The trail travels the length of the park from south to north marked with blue dashes on trees. It starts off along a broom gravel path for about a quarter mile. Then the trail turns to singletrack the rest of the way.
This trail is very rocky in many places. One very difficult section is when the Mennen Trail meets the Kinnelon-Butler Trail
. These two trails share the same path for about a half mile. The Mennen Trail makes a sharp left turn and joins the Kinnelon-Butler Trail
. Soon the trail begins a very steep and rocky descent. This is the most difficult section of hiking in the entire park.
The Kinnelon-Butler Trail
and the Mennen Trail part ways in front of a large glacier erratic with the Mennen Trail turning right and continuing north. The Mennen Trail becomes the Montville-Butler Trail
when the path reaches a trail junction with the RS Trail (Red with White Stripes)
. This is near the north border of the park.
