Start at the Lafayette Place Campground. Hike up Cannon Mountain via the Hi-Cannon trail then backtrack and hope on Kinsman Ridge trail going out over North Kinsman and South Kinsman. Turn around at South Kinsman and hike back until you get to the Fishin Jimmy trail. Take that down to the Lonesome Lake hut and then take the Lonesome lake trail back to the Lafayette Place Campground.
When an opportunity arises I intend to make a go at this loop, thanks to those who have made this a notable route. The Kinsmans are not only a favorite of mine but I also think they're the most underrated peaks in our region!
