5831 Dunker Church Road, Sharpsburg, MD 21782, (301) 432-5124
You might be in town for a wedding, but if you're looking for some history, stop by a battlefield that has the distinction of being the bloodiest day in American history. It's like Gettysburg, but not as crowded.
11100 Fort Frederick Rd
11100 Fort Frederick Road, Big Pool, MD 21711
It's a park to hike around in and it's an old fort that has been through three wars. Staff and volunteers dress up in 18th century clothing and talk about what life was like.
The C & O canal is another fun place to hike around. It used to be...you guessed it: a canal! They created a path beside the old waterway and there are a few trees.
