In winter, when the road is closed to private vehicles, you can opt to reach the top of Mt. Washington via a guided tour in one of the four-wheel-drive vehicles that leave from Great Glen Trails Outdoor Center, just south of Gorham, on a first-come, first-served basis. Great Glen's nine-passenger vans are refitted with snowmobile-like treads and can travel to just above the tree line. You have the option of cross-country skiing, tubing, or snowshoeing down.
