Aryan Valley, historically known as Dah Hanu region, is an area comprising four village clusters — Dah and Hanu in Leh district, and Garkon and Darchik in Kargil district — in Central Ladakh in India. It is inhabited by Brokpa people of Dardic origin. Until its absorption into the Maryul kingdom, Brokpa chiefs wielded nominal autonomy in the region.
