They are formed by the Huating, Taihua and Luohan mountain ranges rising above the eastern and northern banks of Dianchi Lake.

Clouds and mist often hide the mountain sides covered with giant firs and pines where some ancient temples are to be found.

In the cliffs under Luohan Peak, in the Western Hills, are the Longmen Grottoes, with a stone gate leading to the Datiange chamber.

Datiange (Mansion of Heaven) is a stone chamber carved out of the cliffs and is regarded as the finest of the Longmen Grottoes.

The relief carving on the walls, the gods, the sacrificial table and the candlesticks are all sculpted following the original shape of the rocks.

Local folklore describes this mountain range as a young girl with her hair drifting into the lake.

The lake itself is said to have formed from her tears, shed while she awaited her lover's return according to local tradition.

On the left, a platform surrounded by a stone railing is the ideal place to welcome the wind and to view the bold cliff.
