The county is located in the basin of the Qing River, a right tributary of the Yangtze. The river is flanked by mountains on both sides, the tallest of which - the Tianzhu Mountain - is 2,542 metres (8,340 ft) tall. The river is dammed by the Geheyan Dam (located within the county) and the Gaoba Dam (located in the neighboring Yidu County-level City, but flooding some of the Qingjiang River valley within Changyang County as well). The resulting reservoirs provide the main water transportation route throughout much of the county.

Transportation

The new Yichang-Wanzhou Railway crosses the northwestern part of the county, with two stations - Langping and Hejiaping - located near the eponymous towns of the county.

The China National Highway 318, and the newly constructed Shanghai-Chongqing Expressway (G50) run roughly parallel to the railway. Building the expressway in this area required the construction of a number of tunnels and remarkable bridges, such as the Longtanhe Bridge just outside Langping Town.^[7]
