The Big Pool Campground at Fort Frederick State Park is the put-in for this stretch. If you use this as a put-in, please arrange to leave the cars at the visitor center, not at the campground, so as to not deprive a camper of a site. An alternate access point is McCoy's Ferry launching ramp about 2.7 miles downstream from Big Pool. North Mountain C&O hiker/biker campground is about 0.4 miles below McCoy's Ferry and the Four Locks boat ramp and picnic area is another mile lower. Dam # 5, located about 9.5 miles downstream from Big Pool, requires a rough portage on river left and is also a potential access point. Jordan Junction C&O hiker/biker campground is about 15.2 miles below Big Pool. Take-out is at the confluence of Conococheague Creek with the Potomac at Williamsport, MD. A run from Dam #5 to Williamsport is about 7 miles long.
