Tips from the Community
Lovely natural park on the way between the W&OD trail and Wolf Trap National Park/concert venue. Its great advantage is that the trail is fully paved, so still passable in wet or rainy conditions (though you may still encounter puddles). One of my local faves and highly recommended!

For biking, wet conditions will make this trail pretty tough going, and this ford in particular can be dicey if the stream is swollen from rain. Suggest walking a bike across on the stepping stones if you have to cross, and for e-bikes in particular, best to turn all power off until safely across... In rainy conditions, the stream can even overtop the stepping stones, so alternate routes might be better.

The creek’s banks are often lined with a mix of mature trees, and some interesting rock formations along the water's edge, worn smooth by years of flowing water.

Great place for coffee and food. Usually have free water available by the W&OD trail if you need rehydration on route!

A little pavilion with a bench here marks the entrance to Beth Miller Park, adjacent Trailside Park. If you follow the path from the W&O, you will come to a gazebo with a nice view over the pond.

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.
