The route hasn't been planned yet but there are lots of options, long and short, so it may depend on who turns up. The most direct route is about 200km each way but it's not much further to go down via Jenolan Caves, Oberon, Bathurst and up to Hill End then we could make a loop of it coming back down the Mudgee road. That is an all-tar route now and has lots of great twisties and undulating back roads. There are various scenic detour options so let yahoo know your preference.
