The Mujib Reserve is the lowest nature reserve in the world, with its spectacular array of scenery near the east cost of the Dead Sea. The reserve is located within the deep Wadi Mujib gorge, which enters the Dead Sea at 410 meters below sea level. The Reserve extends to the Kerak and Madaba mountains to the north and south, reaching 900 meters above sea level in some places. This 1,300-meter variation in elevation, combined with the valley's year- round water flow from seven tributaries, means that Wadi Al Mujib enjoys a magnificent bio-diversity that is still being explored and documented today. Over 300 species of plants, 10 species of carnivores and numerous species of permanent and migratory birds have been recorded until this date. Some of the remote mountain and valley areas are difficult to reach, and thus offer safe havens for rare species of cats, goats and other mountain animals.
