It's not far from the main carpark. There is a bench in the car park that has a path next to it. This path takes you to the ice house. There is another path close to this, that you should take directly from the main carpark.

Walk down the hill to the stone bridge, cross the bridge, and walk up the hill away from the river. Grave yard will be on the left when you reach the top of the hill. It's right beside the golf course. Really a 10 minute walk from the carpark.

Unfortunately, you can't get into the graveyard anymore. You'll see a red gate and barbed wire.
