Wadi hiking is a very popular activity in Oman, for both travellers to the country and locals on days out. Down the coastline east of Muscat there are a few wadis that wend down from the mountains, but the walks and swimming that Wadi Shab provides are among our favourite. You start by catching a little boat over the mouth of the river to reach the hiking trails, then you have miles ahead of glorious footpath to explore. The route is dotted with pools for you to slip into to cool off, and if you keep going far enough you'll reach waterfalls and caves all flanked by dramatic rock scenery. The paths through the wadi are mostly flat so the walking itself isn't particularly technical – although it is rocky so sturdy footwear is definitely advised – making it a perfect if you have young ones in tow too.
