For help with more adventurous Empty Quarter expeditions, contact desert specialist Mussallem Hassan, who runs this experienced agency. Born in the sands, he organises full-board five-day trips (OR150 per day, one to three people). For a modern-day Thesiger experience, driving the whole Saudi–Oman border to the UAE takes seven days (OR400 per day for a group; OR2000 per trip for two people).

The celebrated British explorer, Wilfred Thesiger, travelled in very similar territory during his epic crossings of the Rub Al Khali (Empty Quarter) in the mid-20th century. While his journeys were conducted on camel back, today's adventurers travel by 4WD.
