On this holiday we will be trekking through a desert world that has been crossed by nomadic people and their livestock for generations. Nowadays, the area is accessible by 4WD vehicles and there are rough ‘roads' to the various camping places that we will use. We will be trekking on scant trails, however, far away from the route taken by our support vehicle. The underfoot conditions will include dry wadis, open sandy desert and rocky desert known as ‘hamada'. There are also sections of narrow trails that across rocky terrain including some easy scrambling. The tracks and trails we use are generally not difficult. We will walk for an average of 5 to 6 hours on each of days 2 to 6, covering as much as 15 kilometres each day and with a reasonable amount of ascent and descent. This is a relatively short trekking holiday and at low elevation.
