The best thing anybody can do is get the map... walhalla - woods point adventure map by rooftops. You can't get lost with one of those, even if you have offroad GPS still have this as a backup. There is one part where a few people might get confused but Chester explained it all pretty well.
If you come from the Thomson Dam and Merrington's Track you will come from the bottom left track, I have always continued straight onto Donnelly's Creek Track on the top right track and tbh have never gone up that top left track which Chester says takes you to the same place. If you go down the top right track it will come to a very small slightly steep downhill, don't need low range or anything and wouldn't hesitate with a camper. Then when you get to the bottom of that straight away turn right and cross the small creek there and continue on that track until you see a Y intersection. Don't know what happens if you turn left there but continue on down to the right and you will see Little O'tooles camp ground, nicely signed and everything. Not very far past there is a sign that says "Tooles camp ground" which is where we will be camping! The O is missing from that sign for some reason. Very hard to get lost!!
