Mouth of the Monocacy Map
From the Monocacy Aqueduct, you can see the railroad crossing shown here. MD Route 28 crosses it further on upstream. To get here, you need to follow 28 to Mouth of Monocacy Rd. It's a windy two lane road, typical of a lot of the canal access roads. At the end to the right is a boat ramp, to the left is the hiking/biking parking lot.
