Wadi Shab, Oman ****
Wadi Shab is probably the most popular wadi in Oman. It is only one hour away from Muscat. The place starts with a short boat ride, followed by a 30-minute hike, and then a swim to the entrance of a cave. This is a must-visit for anyone visiting Oman and Muscat.
And in case you forget, please carry a waterproof camera as you will get wet, and water shoes as you will need to walk on some very pebbly and slippery surfaces.Also, be careful with the goats at the parking spot, they can be very pesky.
