In a coun­try with no short­age of oases, one stands out above all oth­ers – Wadi Bani Khalid. Fed by a stream of water that flows through the val­ley the entire year, it is always green. Date palms line the shore and the water is refresh­ing­ly cool. If you do take a dip, don’t be sur­prised to feel tiny fish, nib­bling at your skin.
