Sharm el-Sheikh, Egypt
Absolutely fantatic 2 to 3 hours. Booking with Viator really paid off as we had a guide just for my husband and I. Saw lots of other tours bookable at hotels etc but they were in large groups and you end up seeing nothing but dust. Highly recommend you ask for the guide called 'Fox' - he is amazing, takes you further into the desert and looks after you from the pick up at the hotel to the trip back. A really nice man.
