Marshall Hall Boat Ramp

River Access Point

The Marshall Hall boat ramp, part of Piscataway Park, is located at the end of Route 227 in Charles County. There are two ramps and a pier available. The site has 40 parking spaces. From Indian Head highway, Md. 210, follow Route 227 North to the ramp.

This is a popular area for shoreline fishing. The Marshall Hall ramp is situated just above Greenway Flats in the Mount Vernon area of the river. It is open year-round, dawn to dusk, with no ramp fee. Small, hand-paddled boats can be launched from the ramp or from the Potomac shoreline.
