Susquehanna State Park (Harford County, MD)
This is a great park along the Susquehanna River near Havre de Grace, MD. There are numerous trails to give variety to your hikes. We often park near the old mill where it's free and there are bathrooms available in the bottom of the barn at the top of the hill. The trail along the river follows an old railroad track, but there are hilly trails as well that give you an opportunity to enjoy beautiful plants and trees as well as large rock groupings. There's also the occasional wildlife to come across. We recently saw a small deer that decided to follow the trail we had just walked on. We have also parked at Steppingstone Museum, but that means that you will be hiking downhill at the beginning and uphill at the end. You can find more information at Susquehanna State Park .
