Zulthulphuk is the climax of the holy Parikrama of mount Kailash and Mansarovar.

For reaching there one has to pass through the Dolma La Pass which is at an altitude of 5600 metres. From there one descends to the fields of Zulthulphuk which is at 4760 meters altitude.

The trek to Zulthulphuk is considered the most difficult one in the entire outer kora due to the high altitude and the steep climb and down. At the top of Dolma La, there is a place called Shivasthal which is covered with holy flags and the personal things like clothing, ornaments , for , there is strong belief in Tibet that whatever one offers here will be offered back to him in his life in heaven after death. Below the pass is situated the famous Gaurikund.

The final descend brings one to the valley floor from which Zulthulphuk is at a 5 to 6 hours walk. This 5- 6 hours trek is the gentle slope of the valley over grassy fields and clear brooks for several Kilometres before it narrows and turns further south to merge with another valley before reaching Zulthulphuk, where one finds the Miracle Cave of Milarepa – a great saint of Tibet. The cave has the statues of saint Milarepa inside. To the left of this miracle cave is the main altar of Zulthulphuk which has the statues of Sakyamuni and Padmasambhava (guru Rinpoche).

This is a grassy lush green meadow with the river Lachu flowing by. There is basic lodging facility in the form of guest houses in huts or tents. The trek is considered to be very difficult and even horse riders will have to walk for a few kilometres.

From here the travellers get back to the base camp in Darchen, towards the end of their holy Parikrama of mount Kailash and Mansarovar.
