And yet, this desert is wonderful: sandstone cathedrals stuck in the sand, many rock paintings, but also vegetation, beautiful gueltas (desert ponds, it rains every year), wildlife (birds, with among them a nice eagle, gazelles, monkeys and even ... crocodiles!). You don't believe it ? Have a look at the pictures in the gallery, and go there!
You can see the photo gallery of the trek on distant trails (also works on iPhone and iPad).
You will need Adobe Flash Player to see this gallery (unless you use an iPhone or iPad). The lower right button of the gallery navigation bar will allow you to see the images full screen.
If you don't want to install Adobe Flash Player, you can see the trek photos on Flickr. You can also download there pictures in their original size.
Thanks to Google Maps, you will see below the trek map.
Click on "View on a larger map" to see a full screen map and to be able to load it in Google Earth plug-in and see a 3D view. The trek trace you see is not coming from a GPS, so do not try to use the coordinates to perform some actual navigation.
