These are hard to come by along the C&O canal and usually hidden. Always nice to know where to get water.

The Upper Rock Creek Trail winds through a densely wooded area with lots of shade. This is a muti-use trail so expect to see a few mountain bikers on your hike. Also, it will be muddy after a rain so either wait for things to dry out or wear some good boots if you're visiting after a storm. As the name suggests, this is just the upper portion of the trail, and it continues 16 miles southward to the D.C. city limit.
