Fall is one of the most beautiful times of the year to visit Vail. If you time your arrival just right, you can witness the blazing glory of whole mountainsides full of aspen turning to gold. But there is a lot to do in Vail Valley besides enjoying the breathtaking nature show. September and October will be highlighted by uniquely themed events and activities like Vail Oktoberfest, Vail Automotive Classic and Vail Restaurant Month. There are so many reasons to visit Vail this Fall.
