After toll gates continue on to F5 Freeway (as if heading for Southern Highlands).
Take the 2nd Campbelltown exit: sign reads Campbelltown/Bulli/Camden: this exit splits into 2 - make sure you keep to the right which heads for Camden (the left side takes you into Campbelltown).
The exit brings you onto Narellan Road - sign reads Narellan/Camden/Penrith (you will see The Australian Botanic Garden on your left at 2nd set of lights): go straight ahead - through 5 sets of traffic lights after freeway exit and make sure you are in left lane at this point.
Straight after the 5th set of lights, peel off to the left towards Picton on the Camden Bypass.
This is dual carriageway at 100km p.h. and after about 5 mins. becomes two lanes. Pass through the set of traffic lights (the speed limit is now 80km p.h. Continue, and cross over the Macarthur Bridge. (You will see grapevines underneath to the left).
After the bridge there are two sets of traffic lights. Pass through both these but keep to the left, in order to turn at Elizabeth Macarthur Avenue. Turn left: (on open days there will be signs directing you to turn into Elizabeth Macarthur Avenue.)
Drive to the end of Elizabeth Macarthur Avenue and cross the single-lane bridge. Continue on this road, passing Belgenny on your left, until you reach a forked road. Take the right-hand fork and follow directions to the car parks.
Toilet facilities are located in the car park area.
