Among the two chulus,Chulu West is the higher peak. It was first ascended in 1952 by a Japanese expedition team. The Base Camp is situated in a small valley situated at North of Manang, off the main trail to the Thorong La Pass. There is a controversy regarding the name and location of the Chulu peaks. There are several peaks close by and are also a part of Chulu massif but are not indicated in the map. Thus it is difficult to differentiate between the two Chulus. However, the Chulu group comprises of four peaks, two in the east and two in the west. Chulu West may also be called Chulu Central. There is no technical difficulty in ascending this peak but progress can be slow as the slopes are vulnerable to avalanches in certain conditions.
