The Kancamangus Highway is a beautiful drive. It is a very busy road in the summer & fall with tourists in cars. It has some of the best views in New Hampshire. Make sure you pay attention and be ready for sudden stops at the lookout areas, people drive fast & crazy through the road so stay alert. It is approximately a 35-mile road so get gas before you enter. There are some great restaurants on either end where you can stop & get a bite to eat.
