“Grand Canyon of Arabia”
How grand? Pretty grand. Pitched high up in the north of the country, in Ad Dakhiliyah Governate, Wadi Ghul is a dramatic trench sliced into Omani soil. It hits a depth of just over a kilometre, its size amplified by the proximity of Jebel Shams – which, reaching a rooftop elevation of 9,872ft (3,009m), is the country’s tallest mountain. It features in the “Oman & Zanzibar” odyssey sold by Cox & Kings (020 3883 6599; coxandkings.co.uk) – a 12-day affair which delves into the past to combine Arabia and Africa much as Said bin Sultan once did. From £3,155 per person, including all flights.
