Not an overly technical trail, but a definate workout and one that tests your climbing and downhill prowess. Starts out fairly flat with some twists & minor elevation changes for about the first mile or so, then the climb begins. Nice mix of good moderate climbs will get your heartrate up with some short flat sections and a few downhills mixed in. Nothing technical except for a few roots until you get to the top of the hill, then there are one or two short technical challenges. Stop at the top of the hill for the awesome view before tackling the long downhill that is probably the last half mile of the ride. Nothing overly steep, but you will be on the brakes regularly to keep from crashing out on the turns & twists.
1129 Wilson Street in Boyne City. Can't miss it, large parking lot & hill at the end of the street (south of town). Trail starts east of the parking lot.
