大别山
Anhui is quite diverse topographically. The north of the province is part of the North China Plain while the north-central areas are part of the Huai River watershed. Both of these regions are very flat and densely populated. The land becomes more uneven further south, with the Dabie Mountains occupying much of southwestern Anhui and a series of hills and ranges cutting through southeastern Anhui. The Yangtze River finds its way through south Anhui in between these two mountainous regions. The highest peak in Anhui is Lotus Peak, part of Huangshan in southeastern Anhui. It has an altitude of 1873 m.
