It gets very cold as you get close to Patapsco River near the bridge. The bridge does move a little but very secure as you cross it. Be mindful if youβre wearing a skirt (Ms Monroe)

This popular swinging bridge crosses the Patapsco River. It is a wooden suspension bridge with metal cables. 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!
