The village of Koyul is in the Koyul Lungpa valley, which houses an active river that joins the Indus near
Fukche. The river originates at the twin passes Zulung La and Dilung La on Ladakh's border with Tibet's
Zanda County and flows northeast. Koyul is about 8 km away from the junction with the Indus. Between the Koyul Lungpa and the Indus valley to the east is a ridge, which also goes by the name "Koyul ridge". China's claim line of the
Demchok sector runs along the crest of this ridge. The Koyul village is just beyond the claim line (in undisputed territory), but the claim line cuts the Koyul ridge in half and partially blocks Koyul's access to the Indus valley.
Skakjung pastureland, which runs along the right bank of Indus river from China-administered
Dumchele and Tsoskar Lake in south to India-administered
Dungti-Loma in north, lies on the right bank of Indus river and north of Koyul. == Demographics ==
