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!

The Grist Mist Trail passes through the Patapsco Valley State Park, alongside the Patapsco River. For a large part of the trail it also passes alongside the railroad. The surface is mostly paved and quite flat so well suited to families and kids. There are various historic sites of interest alongside the trail, including the famous swinging bridge which was originally used by mill workers to cross the river.
