In lieu of the painfully boring drive from Niagara Falls to Boston, I recommend crossing into Canada and driving east on the north side of Lake Ontario, visiting Toronto and Montreal and, if you have time, Ottawa. From Montreal, drive south to Vermont, which is beautiful this time of year. After visiting Burlington and Stowe, Vermont, continue south on scenic Route 100, through Waterville, Waitsville, Warren, and Killington. In Killington, pick up Route 4 to Woodstock, Vermont (no relation to the famous 1968 music festival of the same name!), stop for lunch at Simon Pearce in Quechee (after lunch, make sure to park near the Quechee gorge and walk over the bridge to check out the spectacular view), and then pick up I-89 to I-93 to proceed to Boston.
