The Wahiba Sands is a large region of the desert just four hours drive from Muscat. The geology is mixed: in the north there are smaller hills and wide-range areas, in the east there are hills rising up to 100 meters against the sea, and in the south, at Barr El Hikman, there is a vast expanse of flat sand with challenging salt pads and home to gigantic colonies of winged creatures relocating.
