Swinging Bridge on Grist Mill Trail
Highlight • Bridge
It is best to walk over the bridge as it is not very wide and there may be pedestrians.
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.

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!
