It is on the banks of the Tsari Chu river close to the McMahon Line, the de facto border with India's Arunachal Pradesh.

It is also a key part of the Buddhist Tsari pilgrimage, made once in twelve years, that makes a wide circumambulation of the Dakpa Sheri mountain.

Dakpa Sheri (or Takpa Shiri), a mountain peak to the west of Migyitun, is regarded so sacred that its circumabulation is believed to derive as much merit as the circumambulation of Mount Kailas.

Taking these factors into account, they promised that the border would be drawn short of the high ridge line, and avoid including the annual pilgrimage route in Indian territory as far as practicable.

The Surveyor General of India made adjustments to the McMahon Line boundary "based on more accurate topographical knowledge acquired after 1914".
