Waller park or Riverside park have grills and it's easy to get from one place to the other along the trailers or if you don't want much hiking driving for one to the other is easy. Open from dawn to dusk.
There is a park very, very near Vickery Creek Trail with lots of grills, volleyball nets, play areas, etc. Just drive along the river and look around.
Sorry no grills, it's all about the trails, history and the beautiful falls
It is only trails. I couldn't see any picnic areas or gills.
