The highlight of the canal has to be the tavern, lock and boat in Maryland across from the Great Falls Park in Virginia. It’s only a short walk here to a view of the falls from the ecologically important Olmsted Island, which was preserved by the son of the famous landscape architect. There are limited boat rides on Saturdays until mid October. Williamsport has a much more elaborate and functioning canal boat exhibit, but their rides are currently suspended. If time allows, I would like to come back next year to bike along the multi-state canal route.
