There are actually a couple of spots here. Heading east at the brow of the hill, there is a dirt track to the left that apparently leads to a spot.
We stayed at the second dirt road (this is a small dirt loop road, so take the third dirt road if you miss the second).
If you end at the bottom of the dip at a big open gravel pit on the left you have gone to for.
A couple of bays for RVs for others to get past if need be.
Very little traffic noise. There are regular trains with horn blasts coming from over the ridge on a regular basis.
It's disappointing in that there is a lot of rubbish over the edge (you can't see it from the Rav) and a lot of toilet paper from freedom campers in the bushes.
