River Bottom Park is sandwiched between the Potomac River and the Chesapeake and Ohio Canal in Williamsport, Maryland, just down the road from the Williamsport Visitor Center. In addition to a few picnic tables and sports fields, the park has a concrete boat ramp suitable for launching motorized and hand-paddled watercraft into the Potomac River. The park is open from dawn until dusk year-round, and there is no fee to launch boats of any type.
