The Y camping is along a road, but there was no traffic noise at night and little traffic during a Friday afternoon.
The camping area at the inn in Frostburg was quiet. However, once you get to the inn the camping area is up a steep ramp. Be prepared to unload you gear and make a couple of trips or suffer. I thought I was going to pull a muscle pushing the loaded bike up that ramp. No way was I going to try to control it fully loaded the next morning. Carried my bags down then walked back up for the bike.
