Chengdu is generally higher in elevation than Chongqing, with an average elevation of approximately 500 meters (1,600 feet) compared to Chongqing's average elevation of 244 meters (801 feet). Located in the western part of the Sichuan Basin, Chengdu's terrain is predominantly flat, while Chongqing is famously known as the Mountain City due to its rugged, hilly landscape and significant variations in altitude throughout the urban area. While Chengdu's base elevation is higher, both municipalities contain mountainous regions at their edges that reach much greater heights, such as Chongqing's Yintiao Ling at 2,797 meters and peaks in Chengdu's western administrative areas that exceed 5,000 meters.
