This trail section passes near Mount Desor, the tallest point on Isle Royale at about 1,362 feet elevation. Finding the summit can be tricky because the ridge is completely covered in trees. If you choose to venture off trail to find the summit, make sure to have a map, compass, and the knowledge to use them together.
