Wadi Shab is one of the last places in Oman where you can chill in fresh blue water surrounded by mountains. The true reward of this full-day experience is the waterfall in the cave; locals say it's an oasis.

To discover this amazing destination, hidden away in the canyon of the dry river Wadi-Shab, begin the tour with a two-hour drive from Muscat. Along the way, take in the truly otherworldly landscapes of Oman. 

Stop at a local coffee shop to try an energizing Omani tea before arriving to the destination. After a very quick boat ride to the other side of the bank, embark on a 40-minute hiking journey.

The canyon will show you not only the power of nature, but also the lifestyle of local farmers. To this day, farmers do their rocking in rough, rocky lands, using the old irrigation system as their water supply.

Bring along your waterproof cameras and shoes, because, when you reach the lake, you'll want to snap some photos and walk around through the magnificent site. On the way back, stop to see a beautiful lake located in a sinkhole.
