This trail is far less technical than the Marienville Bike/ATV trail with very few rocks and roots. The majority of this trail in on forest logging roads but there seemed to be way more tough climbs. My lungs were burning. Trail is fairly well marked with yellow diamonds and arrows.
From Rt 66 north of Marienville and Pigeon, turn right onto Forest road 395 and follow back to the trailhead where there's ample parking and a public bathroom.(basically an outhouse)
