Alexandria — As the seasons change, so do the activities that keep us busy. With crisp air, apple pie and leaf-peeping upon us, we say so long to flip flops, air conditioners and barbeques. And while it may not always feel like it, the fall season is officially here and there is no better time to grab family and friends and see what the city has to offer.

“There is no more beautiful place to live than Alexandria in the fall,” said Mayor Bill Euille. “There are so many things to do at this time of year, from festivals to high school football and youth sports leagues.”

Winter will be here soon enough, so before bidding farewell to a fleetingly beautiful time of the year, get out there and make the most of fall with this list of 20 things to do in Alexandria.
