This trek is
the old expedition route to Gangkar Phuensum and, with

special permission; it might be possible to extend the trek
to the base of the mountain itself, though this is rough,
difficult route. The route is through a forest of Cyprus,
juniper, spruce, hemlock and maple. Along this part of the
trail between Tsochrnchen to Duer Tsa chhu, it may be possible
to see musk deer, Himalayan bear, and herds of blue sheep.
The main highlight of this trek is the Hot Spring (known for
healing properties).
