One small modification that I would suggest on this part of the loop based on some local knowledge: After you come down off Mt Washington, take a right on RT 302 in Glen. Follow 302 for a short distance to the village of Bartlett. In Bartlett center take a left onto Bear Mountain Rd. Bear Mt. Rd goes up and over the ridge (up, down, nice twisties) then drops you into the Swift River Valley on the Kancamagus (Rte 112). The main poiint is that will bypass the congested villages of North Conway and Conway. Unless you're looking for some Factory Outlet shopping, you don't want to roll through North Conway. Besides Bear Mt. Rd is a hoot. It is steep enough that they close it during the winter months, but in summertime it's a great detour.
