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

Lock 15 marks the beginning of the "Six Locks" series, which raises the canal 50 feet past Great Falls. Built from red sandstone boulders transported from Seneca, these locks differ from the other granite-built "Seven Locks." From Lock 15, hikers can enjoy beautiful views of the Potomac River.

Accessible via the C&O Canal path, the best parking is at the Great Falls Tavern, with a large lot nearby.

The trail, which crosses the river’s floodplain, is handicapped accessible, though dogs are not permitted. For fewer crowds, it's best to visit early in the morning, around 8 a.m.
