There are two kinds of motorbike tours:

This is a long trip with many staging posts. As in a true rally each day you'll start and end your trip at a new spot, the only difference is - no haste is needed. During the safari you'll be offered to stay overnight in a tent or in a hotel at the end of each staging post:

During this safari your starting and arrival points are the same. Each day you start a new round-trip to the desert and come back to the initial point in the evenings. The idea of this tour is to combine adventures with comfort, so a nice hotel is always a starting point for all day trips.

The spots you may visit during these tours are: Cairo  the Red Sea (Hurghada & Sharm El Sheikh), oases of Sahara
