Devonian Reef (Derby)

I'm thinking you are referring to Windjana Gorge where there is certainly Devonian Reef, & maybe Tunnel Creek & Bell Gorge? (No Devonian reef at the latter two that I recall).

Anyway if that is what you are referring to, you will have no problem accessing them in your Xtrail, the road is a graded gravel road which will be dusty & corrugated in places & yes you will be able to explore yourselves. No River crossing. The track from the campground to Bell Gorge is rocky in places so will need slow going but quie manageable.

Biggest risk is from other drivers who go too fast, just slow down & keep well left whenever anyone is approaching you & when cornering.

Hi Carlo

From the Great Northern Highway you have Geikie Gorge near Fitzroy Crossing. Easy access and you see it from a Department of Parks and Wildlife boat trip which is not expensive.

We drove from Derby back to the Highway then to Fitzroy Crossing to see Geikie Gorge, turning back a little way to the Leopold Downs Road to Tunnel Creek and Windjana Gorge before continuing north east on the Gibb River Road (see My Blogs 2008). This road was quite rough, but no water crossings in the winter months unless unseasonal rain and would be not problem for your Xtrail.

The Gibb River Road from Derby to the Windjana turnoff is good and partly sealed if you do the circuit the opposite way to what we did.
