Alton, New Durham, Barnstead, Bow lake, Barrington via Nippo

Lots of turns and hills.  Bring a map for the turns, especially in Barnstead.  If you go too far on Ridge Rd or North Barnstead Rd, for example, you'll end up on dirt that will take you out in the wilds where you'll be eaten by a Yeti.  

However, there is a mile or so of (mostly) good dirt on John Tasker Rd/Province Rd in South Barnstead.  It's not a problem.  You'll come out at Bow Lake and eventually back on 126 in Barrington.
