Lake Champlain sprawls more than 100 miles south from Canada, forming the border between New York and Vermont on the north. Visit outdoorsy downtown Burlington in Vermont, for handicrafts, live music, and food. Or visit the islands within the lakeâIsle La Motte, North Hero, Grand Isle, South Heroâfor summertime water recreation. In the wintertime, ski the region's Green Mountains.
