History

Bumla is one of the official Border Personnel Meeting points between the Indian and Chinese armies. The 14th Dalai Lama crossed near here in 1959 on his way to Tawang, and the pass carries the Stone of Peace marking joint ceremonial meetings.

Culture

Soldiers host visitors with tea at the border post. Photography is restricted at specific points — always ask, always comply.

Photography tips

Flat light dominates. Shoot detail: prayer flags against snow, the boundary cairns, the faces of the escorting jawans (with permission).
