Straub Brewery is the strongest reason to stop in St. Marys. Founded in the 1870s and still tied to its founding family, it is one of the oldest historic breweries in the United States, with a visitor center and tap room close to the original brewing operation.
The draw is the continuity: German immigrant brewing, a mountain town, and a business that never had to become a theme park to be interesting. Check ahead for current tour times before making the drive.
