Physical map of Hebei
Physically most of central and southern Hebei lies within the North China Plain. The western part of Hebei rises into the Taihang Mountains (Taihang Shan), while the Yan Mountains (Yan Shan) run through northern Hebei, beyond which lie the grasslands of Inner Mongolia. The Great Wall of China cuts through northern Hebei from east to west as well, briefly entering the border of Beijing Municipality, and terminates at the seacoast of Shanhaiguan in northeastern Hebei. The highest peak is Mount Xiaowutai in Yu County in the northwest of the province, with an altitude of 2,882 m.
Hebei borders Bohai Sea on the east. The Hai He watershed covers most of the province's central and southern parts, and the Luan He watershed covers the northeast. Not counting the numerous reservoirs to be found in Hebei's hills and mountains, the largest lake in Hebei is Baiyangdian, located mostly in Anxin County.
