Big Pool Campground / Fort Frederick State Park Potomac access
American Whitewater identifies the Big Pool Campground as the put-in and advises staging cars at the visitor center rather than occupying campground sites. Maryland DNR and NPS establish the surrounding public park and Potomac access context; confirm the current carry, hours, fees, parking, and river entry.

McCoy's Ferry River Access
American Whitewater identifies McCoy's Ferry as an alternate C&O/Potomac access point. Confirm current ramp, parking, road, and park conditions before using it as a bailout or staging location.

Four Locks River Access
American Whitewater identifies Four Locks as an access point and picnic area; the C&O Canal Trust lists the Four Locks boat ramp. Confirm the current launch and parking status.

Dam 5 portage / access boundary
American Whitewater identifies Dam #5 as a possible short-run access and a rough river-left portage for longer runs. The NPS warns that Dam 5 is a high dam requiring a portage on either side; scout from upstream and never run the structure.

Williamsport River Bottom Park / Potomac Park boat ramp
American Whitewater identifies the take-out at the Conococheague Creek confluence in Williamsport. The C&O Canal Trust documents Riverbottom Park’s Potomac boat ramp and parking context; confirm the current ramp, shoreline, parking, and the downstream dam boundary.
