Swinging Bridge, Patapsco Valley State Park
Highlight • Bridge
On the bridge you'll have great views of the river and surrounding woodland.
It isn't too high up, so even if you're afraid of heights it's still worth passing over the bridge. Be courteous of other pedestrians as the bridge is fairly narrow!
