No. I don't think it's allowed for overnight activities. Best to call Centerville City offices.
Yes, there are places on the south side of the creek in many areas that a tent can be set up. I've camped up there myself. There's also several camping areas once you reach the waterfall which is 2 1/2 miles up
Its a day-use-only trail. And its a walking trail that runs along the creek, there really aren't shoots big or flat enough for a tent.
