Mount Airy was established in 1894 as a small railroad town. It's heart is still the Mount Airy train station which houses the Mount Airy Historical Society Museum and connects to our beautiful Rails to Trails and Watkins Park. Our downtown Main Street is the center of town activities including the Fireman's Parade, Celebrate Mount Airy, Oktoberfest, Spooky Trail, and A Main Street Christmas. We have approximately 350 small businesses within the town limits and Mount Airy lies in Carroll, Frederick, Howard and Montgomery counties. We ARE the heart of the four county community.
