The sultanate of Oman shares little with the United Arab Emirates aside from a border: The staggering peaks in Oman’s landscapes come from mountains not skyscrapers; its dramatic coastlines owe little to man-made engineering; and the unending hubbub of Dubai and Abu Dhabi is contrasted here with the sheer silence of Oman’s numerous wadis, or ravines. But don’t expect this idyll to remain unspoiled for long. Oman has lately been in the throes of a hotel boom of Dubai-like proportions: Alila Jabal Akhdar opened against a staggering mountainscape last year; next up, Anantara is planning two resorts — a rival for Alila in Jabal Akhdar and another along the Dhofar coast in the south — and Radisson Blu moves in to Sohar, a historic port in the country’s northern reaches. Four Seasons, W, Kempinski, Fairmont and Aman are said to be planning forays.
