Difficult Run Trail

Highlight (Segment) • Trail

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.

Difficult Run Stream Crossing on Cross County Trail

Highlight • River

This is one of the points where the Cross County Trail crosses Difficult Run Stream. Depending on the amount of rainfall and the time of year, water levels may be elevated, so it's important to exercise caution.

Difficult Run

Highlight • River

This stream branches off from the Potomac River, winding along the Difficult Run Trail. Its name isn't from the challenging nature of the trail itself, but rather from the sharp bend in the Potomac near its mouth, making it difficult for long boat-men to navigate.

Difficult Run Stream Stepping Stones Crossing

Highlight • Bridge

Definitely recommend to use the concrete pillars to cross. The concrete section for riding through is extremely slippery due to algae.
