The border starts in the north at the tripoint with Kyrgyzstan, proceeding west, north-west, north-east along the Syr Darya river and finally north-west to reach the Qurama Mountains. The border then follows this range westwards, before turning south in the vicinity of the Uzbek town of Olmaliq at the Syr Darya river. The next section of the boundary is extremely convoluted, with a long protrusion of Tajik territory (Zafarobod District) and a series of irregular lines; eventually the border proceeds roughly southwards before turning sharply west upon reaching the Turkestan Range. The border then follows a ‘C' shape, with Uzbekistan's Zaamin National Park and the Turkestan Mountains in the north, the Zerafshan Range in the middle, and the Gissar Range in the south. The border then follows a roughly southwards line down to the Afghan tripoint; part of the border follows the Kofarnihon River, and it traverses the Babatag Range and Tuyuntau Range.
