Hikers will meet at Violette’s Lock, #23 on the C&O Canal at 11:00 am. From River Road, turn down Violette’s Lock Road and drive to the end and park at the gravel parking lot.

The hike will go from Violette’s Lock to Pennyfield Lock and return; round trip is four miles. Hikers will view lock #23, the inlet lock #2 and feeder dam #2. We will view the historic milestone that reads, “22 MILES to W.C.” There will be splendid views of the rapids in the Potomac River as we walk along the towpath. We will walk by sheer cliffs on the berm side of the canal that are 150’ high. We will walk past culvert #30 which carries the Muddy Branch beneath the canal. We will stop at lock #22, known as Pennyfield Lock before returning back up the towpath. Total time for the hike is two hours. Hikers should bring water, lunch or a snack with them.
