McMahons Mill
Maryland Recreation Site
At Canal Mile 88 is a former private campground with campsites for recreational vehicles and tents. The site was located close to the Dam #4 boat ramp. A museum featured artifacts from the civil war era.
Note: McMahons Mill was damaged by high water in the fall and winter of 2018. It is currently closed during a reconstruction of the canal from McMahons Mill to Lock 49, approximately one mile. The parking area at McMahons Mill is also closed. The $18 million project will raise the level of the towpath to avoid flooding and damage to the wall. The canal has established a detour along local roads.
