McKeldin Falls is a rapid on the South Branch Patapsco River in the McKeldin Area of Patapsco Valley State Park. The blogger parked by the railroad tracks near the junction of Marriottsville Road and Marriottsville Road 2, crossed the road, and followed the trail along the river. At the top of the hill by restrooms and a paved road, turn right and follow the road to the parking area where it dead ends. A path descends from there to the falls on the McKeldin Rapids Trail.
