Route 543 at Walters Mill Road at Deer Creek bridge. ADC Map, Page 10, Coord H6. Parking is available at the intersection. If not, drive east (downriver) on Walters Mill Road. There are break in the berm that are large enough to park.
Clearly, the road is public property, but the land between the road and the river is not. However, I have been here often and seen many other people as well and never been told to leave. There are no "No Trespassing" signs.
This is a hike along a pleasant dirt road with the creek on one side and a working dairy farm on the other. One can hike downstream about a mile to Sandy Hook Road. One could then hook up with the Deer Creek Conservation Area off Sandy Hook Road. (ADC, Page 10, A7).
Walters Mill Road is traveled. However, it is straight and the fact that it is a dirt road limits the speed. Drivers seem more than courteous.
Each time I have taken this walk, some 30 curious Jersey cows have inevitably come down to the fence to check me out. Certainly a nice experience for young kids who probably haven't seen a cow up close.
Note that the fence is electric. I have found that agricultural electric fences scare the wits out of people. Unlike fences around prisons, they not designed to be lethal. Rather, to condition the cows to stay away. Clearly, if you do touch it, and it is active, you will know it.
On the creek side there is a berm which is several feet above the road. I assume this is man made to avoid floods from taking the road with it. However, there are frequent drainage cuts which permit access to the creek. At many, there are sand bars, at least during low water, which permit you to get right down to the water.
There really are no houses near the road. There are however, a number of driveways, and I carry a walking stick as some kind of confidence builder against an aggressive dog. However, I have never seen one. My general feeling is that the population of H arford County has grown to the point that no one really wants to risk a law suit by letting their pooch free to molest passing hikers. I'm not sure this is universally true throughout the county, but seems to be the case here.
