fellas, you prob already know this but if not you can get on track in a few different places. seems most start at cole rd or flynn rd (turn right off great eastern hwy) and turn left (east) when you see power lines. The best photos etc ive seen are from flynn rd on (east).
I personally have only done from the very start ,where the tanks are ,until cole rd when my young bloke got car sick and I exited via the next track past cole rd on left. The bit ive done was just a lot of rocky bumps etc. Still ok, but it seems most prefer from flynn rd on. Which is where i will start next time.
Hope this helps
google earth is good
