Wadi Mujib, also known as Arnon Stream, is a river in Jordan that flows into the Dead Sea. It served as the northern boundary of the kingdom of Moab in ancient times. The river is now part of the Mujib Biosphere Reserve, offering adventurous hikes and canyoning experiences amidst stunning rock formations. With its diverse flora and fauna, including over 300 plant species and various migratory birds, Wadi Mujib is a haven for nature enthusiasts and birdwatchers alike. The reserve's rugged landscape and year-round water flow from seven tributaries make it a biodiverse hotspot worth exploring.
