Caravan on the Northern Yilgarn Conservation Reserves trek?

Thanks for the advice Paul. The trek I was hoping to make is the one outlined in the ExplorOz Treks section of the same name. It includes an approximately east-west link from Kurrajong Rockhole in the east to Mt Geraldine in the west, through the Mt Manning Nature Reserve, before heading north to Mt Elvire. Are the more difficult/constrained tracks you refer to likely to be in the Mt Manning NR section? The track notes give distances and directions, etc, but very little description of the status of the roads/tracks themselves.

It's so much easier when you use a computer instead of an i or A tablet! I've now looked at the trek notes and the picture of your rig again and am pretty certain that if it were mine I wouldn't take that van into the bit of the trek that is north from Koolyanobbing.
However if you were to start in Bullfinch and follow the Bullfinch to Evanston Rd I'm sure you'd find some reasonable spots to camp along that road and you could do day trips in. It is certainly worth seeing the Helena & Aurora Ranges, but you will get some stripes on your 200 Series' paint work.
I've been into the Mt Manning Range several times and for the life of me I can't see what is so special about them. Perhaps if you are a botanist if might appeal, but there were very few birds and the range itself is very nondescript.
The hills along the Bullfinch to Evanston are quite spectacular, so don't feel you're necessarily missing out if you only do that part of the trek. And you can follow the Evanston to Menzies road out of there to the east through some interesting old mining towns and link up the Golden Discovery Trail.
But you'll need a lot of fuel because there's none to be had north of Westonia or Southern Cross until you get to either Kalgoorlie or Leonora (ie none in Bullfinch, Koolyanobbing, Menzies, Ora Banda or Broad Arrow). We ran out just near Paddington and a mate who worked at the mine rescued us with some fuel properly belonging to the shareholders of Norton Goldfields Ltd!
I've also driven from the old Jaurdi Station (now DPAW) NNW up past Mt Finnerty and the Yendilberin Hills to Currajong Rockhole and the back into H&A Ranges from the NE, but that was with a camper trailer and I doubt you'd get your van through there unscathed either. It was a lovely drive though.
All the best with it.
Paul

Thanks again Paul. Will follow your advice. By the way, fuel is available in Menzies from a 24-hour self-serve outlet in town (credit card only) - have checked with the Shire.

Cheers,

Mike
