Sorrel Ridge is a primitive hiker-biker campsite located at mile 154. 1 of the C&O Canal towpath near Hagerstown, Maryland, adjacent to the Potomac River and accessible only by foot, bicycle, or horseback.

The free, first-come, first-served site offers basic amenities including a chemical toilet, picnic table, and fire grill, with non-potable well water available mid-April through mid-November (water must be filtered, treated, or boiled before use).

Note that stays are limited to one night per trip, and the site may be subject to flooding after heavy rainfall due to its proximity to the river.
