If you opt for the W&OD trail at Leesburg, it will be a completely different biking experience. The W&OD is a paved rails-to-trails that runs beneath a big power line, is rather treeless and boring, crosses roads, and passes through a number of built up areas. I'm not a fan although tastes differ. The C&O on the other hand just starts to get interesting between White's Ferry and Georgetown. The towpath is still dirt, and hence possibly muddy, until you get to Violette's lock at the 23 mile mark. But before you get there, you pass Edwards Ferry, which used to be another ferry across the river and which was the site of a lock allowing boats from the river to enter the canal, particularly canal boats from the Goose Creek Canal across the river in Virginia. During the Civil War, Confederate guerilla units were crossing the river from White's Ferry to Pennyfield Lock (mile 20) and Union cavalry patrolled the towpath. At Violette's, you look across the river at Trump National Golf Course. The river is partially damned there and a lake is formed by the backed up water. Here you also pass Seneca quarry which provided the red sandstone you see on building in DC like the Smithsonian castle and the broken viaduct over Seneca Creek. The last lock keeper here was John Riley. His family lived in the lockkeeper's house you see until his young daughter drowned in the canal and the family moved away from the water. Eventually you'll get to Great Falls. The walking path to the Falls is still closed, I think, buy you can still see parts of it from the towpath. Traffic on the towpath picks up from here to Georgetown but it isn't too bad. In sum, the towpath has a lot more history to it, river views, and trees than the W&OD Trail does. While the towpath north of White's Ferry is not in good condition, the surface from Violette's Lock to Georgetown is macadam (rocks and gravel mixed with clay) and stays pretty dry. But if you are tired of the towpath experience and just want to get the ride over with, the W&OD is an alternative.
