Wadis are the ravines that slice through the Hajar mountains of Oman. They range from narrow gorges to vast canyons with cliffs over a kilometre deep. Most of our itineraries feature drives through a few, particularly where they offer spots to pause for a picnic or swim.

Our guides know all the best natural pools, which are often located amid stands of bucolic date palms, banana plantations and orchards of peaches or mangos. Wet suits are not necessary, even in winter. But women are obliged by local custom to keep covered – a pair of leggings and baggy shirt will suffice!
