Park Mills Boat Ramp offers a concrete launch for small vessels (canoes, kayaks, and jon boats under 16 feet) on the Monocacy River just south of Frederick, accessible via Route 28 and Park Mills Road.

The site features a 12-foot-wide concrete ramp, medium paved parking lot with 15 car spaces and 3 trailer spaces, and a turnaround area, operating sunrise to sunset with no fees required.

Note that the river can be shallow and rocky, and there are no restroom facilities on-site.
