If you are looking for something that is out of this world, then you should check out Saudi Arabia’s renowned Al Wahba Crater, situated some 250 kilometers from the city Taif. Located in the middle of the desert, and measuring 1.3 kilometers across and 200 meters deep, there is no doubt that this is one of the Kingdom’s most dramatic natural wonders.
As geologists discovered in the 1960s, Al Wahba Crater is actually a maar crater.  Maar craters are formed when a volcanic eruption occurs, with the magma coming in contact with underground water. As a result, we have a vibrant formation that resembles a gigantic quicksand, leaving visitors of the crater in complete awe. In addition, the bottom of Al Wahba Crater is covered in sodium phosphate, which, when it rains, gets pushed up to the surface, giving the location a mesmerizing milky appearance.
