Pennyfield Lock

Pennyfield Lock is part of the C&O Canal National Historical Park. The stretch of towpath west of the lock is especially good for migrant songbirds in the spring.

Directions: from the Beltway (I-495) take River Road (exit 39) west 3.3 miles to Potomac. From the intersection with Falls Road (2nd traffic light), continue on River Rd. 5.1 miles to Pennyfield Lock Road on the left. Take this road to the very end, bearing left at the bottom of the hill, and continuing to a small parking lot where a gated road leads to the lock just east.
