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)

The Patapsco Valley was Maryland's first and remains its largest state park. The 14,000 acres (5,700 ha) are made up of forests, winding rivers and cascading waterfalls. It's a great place for hiking, camping, canoeing, horseback riding and mountain biking. Or simply just bring a picnic and relax by the river. Some historical sites are also worth visiting in the park such as the Thomas Viaduct and Orange Grove Flour Mill.

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!
