What is the best route from Boston to Quebec?
I am planning to drive to Quebec from Boston this summer. What is the best route to take to Canada? Should I go through Vermont, New Hampshire or Maine? How long does the trip take? One we cross the border into Canada, is there anything to do on the road to Quebec?
I should have been more specific: I meant Quebec City

Depends what part of Quebec you are going to. Qyebec is larger than most of the US states.
If you mean Monreal, take I-93 into New Hampshire, than take I-89 thru Vermont to the Canadian border and AutoRoute-15 from the border to Montreal
I agree with the previous answerer, although expect to make most of your trip throughout the entire state of New Hampshire.
actually i think a better route maybe to to drive to portland maine and then take route 210 right to the quebec border– from portland its about a 6 hour drive thru the mountains of maine into quebec city–very scenic stretch of driving..
thta should say route 201, not 210
