Mile 0 thru 10
Mile 0 - The Georgetown Canal Basin
The canal's first few hundred yards is lined with shops and a series of lift locks. Barge rides are also available here during the summer months. The towpath begins as a red brick walkway along the north side of the canal bed. After a few blocks, the towpath's gravel/clay towpath surface begins. The path is very narrow here, and considering all the pedestrian traffic, makes it very difficult to navigate by bike. The towpath crosses over to the south side of the canal just prior to Key Bridge.
For the first three miles or so, the towpath surface is fairly rough due to the heavy traffic load in the section. This is why I recommend that you use the parallel Capital Crescent Trail. The paved CCT begins at the western end of K Street (under the Whitehurst Freeway). At this point it is not apparent that the two trails are next to each other, as there is a 40-50 foot elevation differential and forest growth between the trails. The two trails meet at Fletcher's Boathouse (mile 3.1). In addition to a snack bar, boat and bicycle rentals are available here. The CCT trail crosses over the towpath about a half mile past the boathouse and heads north to Bethesda and Silver Spring.
By mile 5, the towpath traffic reduces significantly. Between miles 8 and 10 is the area known as seven locks (since there are seven lift-locks here). The canal passes under the Capital Beltway at mile 9.3 and you enter the area known as Carderock. The half mile long building to the north is the David Taylor Model Basin where the Navy tests scale models of new ships
Lodging Tips: You will find the least expensive lodging options on the Virginia side of the Potomac river. Two recommended locations are Rossyln (across the river from Georgetown) and Crystal City (down near Reagan National Airport). Both are easy to access by bicycle (via the Key Bridge), and offer decent bicycle or subway access to the DC tourist areas.
Parking Tips: (Keep this quiet) <grin> A good place to leave your car is at Reagan National Airport's Economy Lot. This lot is only $9 per day (much cheaper than downtown garages), and the Mount Vernon Trail will take you right up to the towpath (via Key Bridge).
If you wish to park near to the trailhead, you should use one of Georgetown's many private underground parking lots. For example, the lot located at the corner of Wisconsin Ave and Water Streets was charging about $14 per day. These lots are pretty secure and should keep your car safe. Cheaper garages may be found just across the river in the Rossyln section of Arlington, VA.
