at the yak land...

you camp at a warm and cosy... yak fur made-of tent...

NOTE:

"There are two base camps on opposite sides of Mount Everest: to the south in Nepal, and to the north in Tibet. The camps are rudimentary campsites on Mount Everest that are used by mountain climbers during their ascent and descent. Supplies are carried to the camps by sherpas or porters, and with help of animals.

Located at an altitude of 5,208 metres (17,087 ft) North Base Camp is in Tibet.
The North Base Camp has vehicle access (at least in the summer months). Climbers typically rest at base camp for several days for acclimatization; to reduce the risks and severity of altitude sickness. Base camps usually consist of long lines of tents with food, blankets, and light.

As of 2002, a visit to the North Base Camp required a permit from the Chinese government, on top of the permit required to visit Tibet itself. At this time such permits could be arranged relatively easily via travel companies in Lhasa, typically as part of a travel package that included hiring a vehicle, driver, and translator."
