Yes belmont south is a great spot, as well as little pelican by the lake and play equipment (near boat ramp). Also may wish to think about Warners bay area, the forshore of the lake as you can walk around it (6km) of shared concrete cycleway and spears point has good play equipment and a long jetty to throw off the kids. Ah I mean somewhere for the kids to explore!
Ah its just paradise here???!!
