From Groveton, NH, travel on South Pond Rd. and follow the Kilkenny Ridge Trail. Devil's Hopyard is an interesting formation that is an option along the trail.
The hike to Roger's Ledge can afford great expansive views if the weather cooperates. I was fortunate to get a couple exposures on this autumn day, as fog and clouds obscured much of the view. I ended up liking the detailed view that the long telephoto offered.
