Semo La (La means "pass" in Tibetan) is a mountain pass situated in the central part of Tibet and gives access to the Chang Tang region. It is found on the so-called Northern Route, north of Raka and south of Coqen in Central Tibet. Travellers use this route as an alternative access route to western Tibet and Mount Kailash, especially when mud makes access by the more southern route difficult. The road crossing the pass is an old unsurfaced track travelled only by a weekly bus and trucks heading west to avoid the boggy parts of the south of the country.
