If you are a little outdoorsy, there is very nice walking around the farm. Past the horse stables and the thatch house, and up to the right through the fence to the fruit orchard... if it's the season, feel free to take some oranges, lemons, sweet limes and naartjies (just as many as you want to eat, not bagloads, please).
If you continue up the right side of the orchard there is a gate and track that heads up towards the plateau which has nice views out to the north (about 1-2km depending which route you take.)
The Buffelspoort Dam is nearby, where you can fish or do water activities (you need your own kit, as there is no entertainment centre). Many people from the city go there (or the nearby Omaramba resort) to camp.
In terms of animal interaction, there are the horses; there are also vervet monkeys and squirrels in the garden and around on the farm. There are also mongooses, meerkats and (occasionally) honey badgers, which are very shy, but if you see one don't approach, they're very fierce. There are also jackals, but are increasingly shy with encroaching human activity.
