Exploring Oman’s mountains and interior involves negotiating difficult terrain. On this private tour from Muscat to Nizwa and Jebel Shams—the latter called the Grand Canyon of Middle East—there’s no need to worry about driving, with a driver-guide with good local knowledge at the wheel. Traveling from Muscat by climate-controlled 4WD, you’ll be whisked around Nizwa, Oman’s old capital; visit its fort and souk, and climb Jebel Shams for stupendous views and glimpses of remote villages.
