Head along Great Eastern Highway and turn right into Flynn Road (just before Lakes Roadhouse at the Great Southern Highway intersection).
Turn left onto the track underneath the powerlines and you can follow it along until left into a major dirt road (Yarra Road), left at the bitumen (Gt Sthn Hwy) and left at The Lakes. You'll then be pointing home.
If you find the powerline track too much, go back to Flynn and go the other direction along the powerline track... it's typically less cut up. Any right turns will take you back to the highway, where you'd then turn left for home.
There's usually heaps of dudes out there so you're not alone. Give way to bigger groups or we're not friends any more.
