Mulgoa Park on Littlefields Road in Mulgoa is a lovely park, still in the Penrith Local Government Area, with clean toilets and plenty of play options.
Edna Dunn Reserve, South Penrith
This is a great park, the only thing that lets it down is that it is next to Northern Road (at that point called Parker Street) and so it is no good if you have a child who is a runner. That said, the park itself is set a long way back from Northern Road, it has great sun shade coverage, and a good variety of equipment. To get to it you go to Mazepa Street, South Penrith.
When I took these photos the sun shade had snapped on one side, but it has since been fixed. There is a slide, a cargo net, a rock climbing wall (for small children), circular monkey bars, instead of a pretend cafe this one has a front that looks like a car, swings, and a climbing net shaped like a spider web. There is only one seat for adults to sit at is my biggest complaint about this park. It is easy to park on Mazepa Street and walk to the park. There were actually also a lot of sticks around and trees so if kids want to look for sticks or rocks for craft, or just to play with, there is space for that too.
