The New England mountains in the fall.

I would suggest the Grand Canyon. Hopefully anyone could catch it on a clear day

for skiers I would suggest Revelstoke Mountain for best skiing and Whistler-blackcomb for the amazing view and awesome ski-in ski-out experience with great ski village. Revelstoke doesn't have much of a ski village but the quality of snow is better than whistler. personally, as a seeker of powder snow and backcountry skiing I prefer Revelstoke.
