Hello, sorry for the delayed answer. Yes, Woodstock is a fantastic place to see the foliage. Rt 100 is one of the best scenic routes in Vermont and we are dead center...so you can drive north or south. Here's a link to a great page of Vermont's Scenic Byways: vermont vacation . com / byways. You can order a wonder brochure with all the Byway listed with interesting things to see along each Byway.
Advice: book very early as all lodging in Woodstock fills early. Hope this helps!
