Wadi Dayqah Dam

Wadi Dayqah Dam sits where two wadis meet in the Hajar Mountains near Quriyat, holding back a striking blue-green reservoir against a backdrop of bare, folded mountains. The drive in follows a dramatic gorge road, and the viewpoints just off the car park give an easy, safe look at the water and the dam wall without any climbing.
There is a landscaped park right by the dam with shelters and picnic tables, so it works well as a free half-day out: look at the view, let the kids run around the park, then head back. Husaak Adventures sometimes runs paid kayaking or pedal-boating sessions on the reservoir — worth checking their page if your children want to get on the water rather than just look at it.
It is a quiet, uncrowded alternative to the busier wadi stops further down the coast road, and a good stretch-the-legs stop if you are continuing on to Quriyat or the Sur coast road.

Water, hats and sun protection — there is little shade at the main viewpoint. Bring swimwear on spec if you want to ask about the kayaking operator.
