Wadi Ash Shab is one of the top highlights of Oman. The narrow canyon is home to crystal clear blue water pools and also a secret waterfall inside a cave. Freshwater cascading from tops of the mountains meet the briny sea water on its banks, creating an environmental diversity, making it stand on a pedestal of its own when compared with the other wadis in the Sultanate. Wadi Ash Shab is located in Tiwi, which is a part of Sur in Al Sharqiyah South Governorate. The place is easily accessible from Muscat, as it lies 140 kilometers from Muscat on the Qurayat,  Sur Coastal Road.
