Montreal is about 3 1/2 hours from Hanover in a straight shot. Ben and Jerrys main plant in Waterbury Center VT. is only about ten minutes out of the way, but you can sometimes have to wait in line for a tour.I'm also just off that route in Montpelier, about an hour north of Hanover, so if you want to stop off, or if you have any other questions about the area, send off a personal message.
