The Kancamagus Highway through the White Mountains of New Hampshire is listed as one of America's most scenic drives.
I agree that it's most definitely scenic-
There's also a gift shop on a covered bridge to satisfy any shopping cravings you may have while viewing all the beautiful nature around you-
Also, if you're a weather buff, the top of Mt. Washington has some of the most extreme weather and there's a museum dedicated to it along the route!
We spent an entire day exploring this area and really enjoyed it.
