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 you’re wearing a skirt (Ms Monroe)

Here, you can explore the paved Grist Mill Trail for a leisurely walk or venture deeper into the woods to find Cascade Falls. The area also features remnants of old mills and the Bloede Dam removal project, an indication of the park's evolving landscape. With shaded woodlands and riverside trails, it's a fantastic spot for a casual walk or an extended hike. Arriving early is recommended, especially on weekends due to its popularity.

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!
