You may park at either the Carderock Recreation Area or the gravel lots across from the Anglers Inn Restaurant. We recommend Carderock as it is slightly closer to walk the towpath to the campsite from there. Search "Billy Goat Trail C - North Parking Lot" on Google Maps for the best directions. From I-495 in Maryland: 1. Take Exit 41 toward Carderock/Great Falls. 2.
