Öndör Ulaan is one of the sums of the province of Arkhangai, founded in 1931 and composed of five villages (Azarga, Bayangol, Belkhi, Dongoi and Khanui). This area has the biggest number of yaks of Mongolia: 42000. In the Southeast of the sum, Mount Öndör Ulaan reaches its highest point at 2142 metres (1,33 mile).
In this sum, we work with many families of the Ar Arvidjin Delgerekh yaks breeders cooperative. These breeders can make small groups discover the different activities bound to yaks breeding and other nomadic activities.
