The Old Man and Profile Lake is a 0.5 mile out and back trail located near Franconia, NH. The trail is good for all skill levels and primarily used for hiking.
The historical sight is very nice and view of Profile Lake is spectacular. A must for the family if you've never been.
This is a great little hike. Growing up, we would stop here every year while camping in the White Mountains. The last time I was there was in 2009 after The Old Man slipped off the mtn. Plans and constuction was underway to expand the area and a memorial of The Old Man. Even without him there it's still worth the trip.
