To avoid any detours: make sure to enter the full address, 4484 Hamilton Hwy, Hesse, into your maps. You don't want to end up 20 minutes down the road at the Barunah Plains hall. It's not nearly as pretty as Barunah Plains!
Once you arrive, get ready for a scenic drive down the driveway, about 1.5km long.
As you approach the homestead, keep following the road and pass the tennis court on your left. Follow the 'Guest Parking' signs.
