The remote valleys and mountains of Tibet are home to a rich variety of wildlife. There is the Himalayan black bear which is present but rarely seen by the public eye. The giant Tibetan brown bear however searching for food in the alpine meadows is a much more common site. Snow leopards in the craggy heights and the common spotted leopard in eastern Tibet are occasionally spotted by alert trekkers.

Less discouraging but no less spectacular are the ungulates of Tibet , which include several species of deer, wild yaks, antelopes, gazelles, blue sheep and the argali, the largest species of wild sheep in the world. Smaller mammals, a panoply of birds, and numerous reptiles and amphibians can be seen while trekking. Generally, large predatory animals are not attracted to camp sites and stay well away from humans.
