Hidden Falls is in Saint Paul, MN. It is one of the parks along the Mississippi River. The falls are actually just a place where the storm drains run off the street and then into the Mississippi River. Which, is a good reminder for people, the things you toss out your car windows or otherwise end up on the street, all eventually make their way into the river. Please, hang on to your garbage, candy wrappers, pop or water bottles until you get home to dispose of them.
Oh, back to the falls, they are pretty hidden but, if you live in the area and go down Mississippi River Blvd. and see Hidden Falls Park, go down into the park, you will see some picnic shelters on the right hand side. Park there and walk past them, once over the hill you will see the path leading down to the falls area. The stone walls and steps are really pretty in there.
