Near the point where Wadi Kabbah runs into Wadi Tayein are the villages of Tam and Tool. Tool is the gateway to high-sided Wadi Dayqah, which makes for an interesting hike. Old cave dwellings are still used by shepherds here and there's all kinds of wildlife (toads, dragonflies, jewel beetles) congregating around the deep pools.
The pools also invite a swim, but don’t for a minute think you’re alone – the steep ravine is a favourite with silent-walking shepherds. The hike runs along the wadi bottom towards Dayqah Dam and is often impassable. Tool lies 10km east of the town of Mehlah, at the end of the sealed road through Wadi Tayein.
