AsiJohn,
Because of the direction you will be coming from (S.A.) if you go all the way to Ballarat and then to the Camp you will be adding about 1 hour to the trip.
Depending on which Highway you come on you should turn off to Snake Valley at Linton or Beaufort.
If you use the Glenelg Hwy: turn-off at Linton and the Camp is only 4 minutes from the turn-off!
If you use the Western Hwy: the turn-off is about 2k after Beaufort. Follow that road all the way to Snake Valley (approx 15 mins).
Both turn-offs are clearly marked with big signs.
I hope you make it over as it would be great to see you before you head off to live in America.
