Wadi Rum, also known as the Valley of the Moon, is a protected desert wilderness in southern Jordan, featuring dramatic sandstone mountains and dunes. Accessibility can be challenging due to the terrain, often requiring 4x4 vehicles or camel rides. While solo exploration is possible, guided tours are highly recommended for navigating the desert and understanding its history and geology. The best time to visit is during the cooler months (October to April) to avoid extreme heat. A typical visit can range from a day trip to several days, with costs varying based on accommodation (Bedouin camps or luxury resorts) and activities (jeep tours, camel treks, hiking). Expect to pay anywhere from $50 to several hundred dollars per day. Be sure to bring sunscreen, water, and appropriate clothing for the desert environment.
