Track from Stuart Hwy via Davenport Ranges NP to the Barkly Hwy - info

It is either the Binns track or the Sandover Highway.

The section from the Stuart Highway to Davenport Ranges National Park is part of the Binns Track,but is in fact a fairly wide gravel road. The route to the north to the Barkly Highway is a private road through Epenarra Station . You need to obtain permission from the station owner to travel along it.Best to phone before you leave home, because permission is not always given especially if they are using it to move stock.

We drove that route in reverse ie from the Barkly to Davenport Ranges & out to the Stuart in early July 2012. Both parts were in quite good condition, indeed most of the Binns track section had been recently graded & the grader was still working.
It is about 110 km from the Barkly to Epenarra, & 120 from there out to the Stuart. There are 2 camping grounds to the south in the National Park. We stayed in both but I thought the one at Old Policestation Waterhole was the nicer, although the gorge at Whisleduck Creek is worth a visit. The roads into the park & the Epenarra road were all in good condition with little corrugation but the Epenarra road was narrow in places & one had to be on the lookout for stock.
My recollection is that it took us about 2 & 1/2 hours from the Barkly to Old Policestation WH (its a further 35 k south from Epenarra into there). It took us a morning from Whistleduck to the Stuart but we were towing & taking our time.

It is pretty well marked but you might need to check with the station as to the correct point of entry into their private road to the Barkly as there are a few station tracks around the homestead.
I think its more scenic than the highway, & if you have the time spending at least a day in Davenport ranges NP
Hope this helps
