Shipton's Arch (Tushuk Tash) -- The world's largest natural arch stands, largely unheralded, about 50km (31 miles) northwest of Kashgar. Located at an elevation of 3,168m (10,394 ft.), the arch towers 366m (1,200 ft.) above the canyon floor. It is composed of crumbling conglomerate and is exceedingly difficult to reach. Eric Shipton, Britain's final representative in Kashgar and an accomplished mountaineer, failed several times from the southern route via Muk and Mingyol, finally gaining access from the north via Artux and Karakum. His wife described the scene: "We found ourselves looking straight across at the immense curve of the arch. Its upper half soared above us, but the walls continued down into an unfathomable gorge below. It was as if we stood on a platform some few feet away from a giant window . . ."

Uighur Tours and John's Information Cafe both run day tours to the arch and charge ¥700 and ¥800, respectively, for a jeep that can hold up to four people and a driver.

Tomb of Mohammed Kashgari -- The tomb of this eminent 11th-century translator lies 30km (19 miles) southwest of Kashgar, west of the charming Uighur town of Opal (Wupa'er). The scholar spent most of his years in Baghdad and is credited with compiling the first Turkic dictionary in Arabic. Hire a taxi (¥120 return) or take bus no. 4 (¥2.50) from Kashgar's Opal bus station (a block south of the Seman Hotel) as far as Shufu, then share a taxi to Opal for ¥5. Donkey carts, charging ¥4, leave for the tomb from under a red-and-yellow arch in the center of Opal. If you haven't sated your appetite for markets after a Sunday in Kashgar, Opal's Monday market offers a smaller scale version, replete with all the usual trimmings -- cattle, donkey carts, and enigmatic faces all vie for your attention.
