Explore freedom's route
Underground Railroad tours are conducted weekly at McAllister’s Mill, located adjacent to the National Military Park on Baltimore Pike. Tours leave from the south end of the Mulligan McDuffer’s Golf Course parking lot every Saturday at 11:00 AM from May through August.
The site, now a ruin with foundations and waterways still intact, was most probably the first site in Adams County that people seeking freedom found on their flight north from slavery. The mill site is privately owned and is not open to the public. HGAC has permission of the site’s owner to access the property.
