Wadi Bih, alternatively Wādī Al-Bayḥ, is a river/wadi that crosses the North-Western Hajar Mountains from the United Arab Emirates, and traversing Oman before returning to the UAE. From the West to the East, it originates in Ras Al Khaimah on the Gulf, before crossing the Omani exclave at the tip of the Musandam Peninsula, past the village of Zighi and into Fujairah at Dibba Al-Hisn, on the Gulf of Oman. The wadi is a popular location for birdwatchers.
