Day trips around Kiama?

[Bagheera]

Wife has booked us into a caravan park in Kiama for the 2nd week of the school holidays, so I'll be dragging the camper down and setting it up in relative luxury (power, water, flush toilets and hot showers). Several days will probably be spent beach-side trying to brown up my translucent skin, but I'd also like to get out and do some 4-wheeling.

We'll be travelling solo, and I don't have a winch, so I don't want to get too ambitious. Just something fun, with a bit of mud or water or some technical climbs/descents would be great. Anything for the kids/wife to explore would also be great.

Recommendations?
