This trek starts at Alice Springs and travels south on the Old South Road taking in some ruins along the way to the small town of Maryvale. It then heads south east to Chambers Pillar which is an amazing rock formation in the Chambers Pillar Historical Reserve. This part of the trek is extremely scenic and is a good introduction to the type of scenery you would see in the Simpson Desert although the route runs between dunes and is relatively easy.

The track to Chambers Pillar is officially not recommended for trailers but other than a bit of sand, a rocky low range 2nd steep descent and patches of corrugations, it is straightforward and many people do bring them. There are red dunes on either side of the track, bits and pieces of historic ruins, and not a car in sight. The track is mostly sand and has good drainage when wet.

You can climb up to the base of the vertical section of Chambers pillar to view the inscribed names of the famous explorers who passed here before the Telegraph and Ghan was built and there's a nice walk around the base of Castle Rock. Late afternoon is the best time to view the rainbow colours of the ridge that glow vibrantly when struck by the golden rays of the setting sun.

Chambers Pillar lies in an Historical Reserve and you do not need permission to enter it. Also, you do not need an Aboriginal Land Permit because you won't be passing through any restricted land.

The camp sites are excellent - great views of both Castle Rock and Chambers Pillar, free gas BBQs, hotplates, fire pits and large picnic tables. The camp sites are not ideal for campertrailers or caravans with bollards making sites better suited to tent campers. Although you can camp in the shade your vehicle certainly won't be. This is a consideration in hotter weather as there is no power to keep fridges or batteries charged.
