In case you're planning a trip, perhaps it's worth noting that Malmesbury isn't really a town to visit on an outing - in my opinion. The town itself isn't very pretty and rather the kind of town that one passes though when heading up the West Coast, or when going to places like Riebeek West, or Ceres.
Please, I'm looking for someone to disagree with me - so if you're keen on Malmesbury, please do leave a comment to say why you love it. I'm just being honest when I say that although the countryside is extremely beautiful, I've never found the town very pleasant at all.
