More details of Our Experience
To access the trail by parking legally you would have to enter Patapsco Valley State Park through the Avalon/Glen Artney/Orange Grove Area. This is located in Howard County. Click on the map to get directions on Google Maps.
You can also access the trail from Ilchester Road but, even if you’ll most likely see cars parked on the side of the road, it’s not legal to park there. You will likely get a ticket or your car towed.
If you want to start the trail from the beginning, once you enter Patapsco, you’ll continue to the right where the signs are pointing out Avalon Area. Once you reach that, you’ll take a left where the signs are pointing to Glen Artney Area. Before you reach the dead end and take a right that goes under the railroad bridge, you’ll see a small parking area to your left. Park there. That’s the closest parking.
That parking is right next to Lost Lake. The lake is closed due to flood damage but you can appreciate it from afar. It’s very pretty and theres a serene quietness there. Continue walking past the lake, and you’ll the sign saying Grist Mill Trail. You won’t miss it since it’s the only trail there and it’s completely concrete paved.
