The quad biking was great fun. We had a guide to ourselves and he showed us some of the 'little five' creatures to be found in the desert - a cartwheel spider, a translucent gecko, a shovel-nosed lizard, and best of all, a sidewinder snake. These fascinating creatures all live under the sand during the day and the guide finds them by spotting tell-tale tracks.

The Namib is in fact the oldest desert in the world. There is a fascinating episode on BBC Planet II about it. The diversity and uniqueness of it are mesmerising. We left inspired and privileged to have been there.
