Wadi Shab lies in Niyabat Tiwi, a village between the capital, Muscat, and the town of Sur. Easy to reach from the Qurayyat-Sur highway; it has at least seven pools of emerald green water and is studded with dramatic boulders. One of the pools is in a cave where light streams in dramatically from above and there are fantastic echoes heard when one swims in it. Kingfishers add glorious splashes of colour. © Red Bull Media House
