The Difficult Run Trail follows the stream from Georgetown Pike to the Potomac River. The trail, which is narrow and rocky in some sections, can be hazardous due to a washed-out portion that is less than six inches wide in places, with a steep drop-off to the stream. While hikers, cyclists, and horseback riders can use this trail, horses cannot pass through the narrow section, and bikes must be carried. Be cautious; it is also very slipy when wet. Swimming and wading in Difficult Run and the Potomac River are prohibited.
