"A beautiful and pleasant river walk with some people camping and go fishing. There are multiple entrances, and a lot of cyclists.
There is only one food truck(hot dogs, ice creams etc.) near the visitor center but on the expensive side. They do accept card payments.
Dogs are allowed on leash, but not permitted on some trails. Please be mindful of the trash, and try to not leave anything but your 👣."

"The C&O is awesome! So beautiful and serene. This is a good spot to enter the C&O Canal towpath. Parking is free, but there's not a lot of it. There is camping here, by reservation, or you can rent the lock house overnight, and it has full plumbing (incl showers and toilets), HVAC, kitchen, and beds."
