Preserving America's early transportation history, the C&O Canal began as a dream of passage to Western wealth. Operating for nearly 100 years the canal was a lifeline for communities along the Potomac River as coal, lumber, and agricultural products floated down the waterway to market. Today it endures as a pathway for discovering historical, natural, and recreational treasures.

Hours are retrieved from the National Park Service and can change without notice — check the official site before you go.
Williamsport, once a thriving and bustling canal town, transported tons of coal up and down the canal from Cumberland, MD to Washington, DC. Take a walk and imagine dozens of boats, workers, and mules moving commerce. Williamsport, MD is at mile 99.8 out of 184.5 miles of towpath. Here you will find unique features of the canal system and other infrastructure that arose with westward expansion and industrialization.
