Road Conditions for Simpson Desert Reserves and Witjira National Park

This is a good run, but a bit overgrown in places.

This track is slow and very rough and sandy in places, take care.

Soft & loose sand with sharp ridges & scalloping when approaching from the west, slow & sandy all the way. Use 16 – 18 psi (Hot tyre pressures), incl. trailers.

K1-Warburton PAR into the Simpson Desert is open.


Take extreme care at the south eastern end of the Rig road as not many vehicles have passed this way in recent years.

Very soft sand after the summer closure.


Very scalloped out on the western dune faces.


Lower tyre pressures to avoid damaging dune faces ( 16-18 psi Hot Tyre Pressures, including trailers).

The Rig road is deteriorating & becoming quite rough; with its clay capping slowly breaking up care must be taken when cresting sand dunes, this track can have corrugations, deep washouts & rutting. Sand dunes between the Knolls track and the K-1 Line are more difficult to cross especially from the west.

PERMANENTLY CLOSED don’t use this track at all unless you have permission from the Oodnadatta Police. (08) 8670 7805

The WAA line is in similar condition to the French line, soft & sandy after the summer closure.

There is already damage to the western dune faces due to travelers not lowering tyre pressures.

Now open to 4wd, no issues reported.
