Saudi Arabia has several ancient sites and natural wonders scattered across the kingdom that are worth seeing, but nothing compares to the mystique that is the Umm Jarasan Cave, located in the desert region of Haret Bani Rashid, in eastern Khaybar. This cave is believed to be one of several lava tubes in the area, caves that were formed within a lava from a nearby volcano, with distinct wall formations. In fact, Umm Jarasan Cave is nestled in the Harrat Khaybar Lava Field, located just 130 kilometers north of Medina.
