Moving still further north, the Chitral and Hunza valleys are flanked by the Hindu Kush and Karakorum mountain ranges. Previously isolated, they now make part of a thoroughfare from the capital, Islamabad, to China: the mighty Karakorum Highway. It’s inaccessible during winter, but easier to visit at other times of year. Late autumn is breathtaking: Ingeniously irrigated green wheat fields weave through the valley floors, the air fragrant with the jasmine-like scent of Russian olives and freshly milled grains, and everywhere are flames of orange, rust and lime-green leaves. The trees on and around the mountains are alive with vibrant Hunza apricots and plums; their fruits are plucked and left to dry in large baskets on the mountainsides, on rooftops and boulders, ready to be eaten in the winter ahead.
