Located in Al Sharqiyah South Governorate, in a place called Tiwi that is part of Sur. It is a 1 hour and 40 minute drive from the centre of Muscat. Areas of this wadi are only accessible by boat, which makes it a good idea to book a trip if you want to make the most of the wadi.
To reach the waterfall cave, which makes Wadi Shab different from most other wadis, you will need to hike for approximately 3km, but it’s absolutely worth it when you get there!
