Changthang Plateau & Valley

1. Mountain Geography & Tectonic Origin

Changthang Plateau and Valley (meaning 'Northern Plains' in Tibetan) is an awe-inspiring, high-altitude trans-Himalayan plateau realm situated in southeastern Ladakh, extending across the international border into western Tibet. Resting at an extreme average altitude of 4,400 to 4,800 metres above sea level, Changthang is one of the highest and most climatically extreme inhabited regions on Earth. The landscape is characterized by vast, undulating steppe plateaus, sprawling salt-encrusted basins, and colossal endorheic (closed-basin) lakes including Tso Moriri (the Mountain Lake) and Tso Kar (the White Salt Lake), both designated as Ramsar Wetlands of International Importance. Framed by barren, wind-sculpted mountain ranges exceeding 6,000 metres at summits like Chamser Kangri and Lungser Kangri, Changthang represents an austere, primordial wilderness of sky and earth.

Geologically, Changthang is part of the Tibetan Plateau uplift, formed by the continuous collision of the Indian and Eurasian tectonic plates. The climate is hyper-arid cold steppe, characterized by intense ultraviolet radiation, ferocious gale-force winds, and extreme diurnal temperature swings that can range from +20°C in the afternoon sun to -15°C at night even in mid-summer.

2. River Systems & Glacial Watersheds

The northern boundary of the Changthang plateau is drained by the Upper Indus River, which enters Ladakh from Tibet near Demchok and flows northwestward through deep crystalline gorges past Nyoma and Chumathang. Along the riverbanks at Chumathang, powerful geothermal boiling springs discharge sulfurous mineral waters at temperatures exceeding 85°C.

The interior of Changthang, however, consists of landlocked endorheic drainage basins where internal streams terminate in massive, brackish high-altitude lakes. Tso Moriri, a 26-kilometre-long sapphire-blue oligotrophic lake perched at 4,522 metres, is fed by the Pharse stream and surrounding glaciers without any surface outflow, creating an ethereal aquatic jewel framed by snow-capped peaks.

3. How to Reach & Transit Logistics

Changthang is accessed from Leh via two primary mountain routes. The southern route to Tso Moriri follows the Indus River along the Leh-Manali highway to Upshi, then branches eastward via Chumathang, Mahe Bridge, and Sumdo to reach the village of Korzok on the banks of Tso Moriri (approx. 220 km from Leh, 6 to 7 hours by car). The northern route to Hanle proceeds further east along the Indus via Nyoma and Loma.

Kushok Bakula Rimpochee Airport in Leh (220 km) is the primary aviation hub. Journeys across Changthang require sturdy four-wheel-drive vehicles (Toyota Innova, Fortuner, Mahindra Scorpio) with high ground clearance, as roads frequently transition into sandy tracks and unpaved gravel outwashes.

4. Entry Permits & Environmental Regulations

All non-residents (both Indian citizens and foreign nationals) must obtain an Inner Line Permit (ILP) / Protected Area Permit (PAP) to visit Changthang destinations like Tso Moriri, Korzok, and Chumathang, issued through the Ladakh administration portal (lahdclehpermits.in) or travel operators in Leh.

Permits and identification are strictly checked by the Indian Army and Indo-Tibetan Border Police (ITBP) at checkposts in Upshi, Chumathang, Mahe Bridge, and Loma. The frontier sector of Hanle (home to the Indian Astronomical Observatory) and Umling La (the world's highest motorable pass at 19,024 ft) requires specific border permit endorsements.

5. Traditional Mountain Hamlets & Heritage

The human heartbeat of Changthang is Korzok, situated on the western shore of Tso Moriri at an altitude of 4,595 metres—one of the highest permanently inhabited villages on Earth. The village is centered around Korzok Monastery (Korzok Gompa), a 300-year-old Drukpa Kagyu Buddhist monastery housing antique thangkas, bronze statues, and an active monastic community.

The nomadic Changpa families migrate seasonally across designated pastures (like Kharnak, Rupshu, and Hanle), moving their yak-hair rebos according to traditional pasture-rotation customs. Their cultural resilience, devotion to Tibetan Buddhism, and deep harmony with the harsh steppe environment represent an extraordinary chapter of human adaptation.

6. Trekking Trails & High-Altitude Expeditions

Changthang offers surreal high-altitude landscape walks. Strolling along the western shore of Tso Moriri from Korzok village towards the wetlands of the southern shore allows visitors to witness changing colors of water shifting from aquamarine to deep navy blue under shifting sunlight. In Tso Kar, walks around the white salt-crusted shoreline offer unique birdwatching.

For expedition mountaineers, Changthang is the base for non-technical 6,000-metre trekking peaks, most notably Chamser Kangri (6,620 m) and Lungser Kangri (6,666 m) overlooking Tso Moriri. Another classic high-altitude trek connects Tso Moriri with the Spiti Valley across the challenging 5,600-metre Parang La pass.

7. Flora, Montane Fauna & Wildlife Corridors

The vegetation of Changthang is sparse cold desert steppe, comprising resilient tussock grasses (Stipa, Festuca), dwarf caragana bushes, and high-altitude cushion plants (Oxytropis, Arenaria) that survive temperatures down to -40°C. Despite sparse appearance, these grasses provide vital, protein-rich winter nutrition for wild herbivores and livestock.

Changthang is a globally recognized biodiversity hotspot for Central Asian steppe wildlife. The Changthang Wildlife Sanctuary protects large herds of the Kiang (Tibetan wild ass, Equus kiang), Tibetan gazelle (Goa), blue sheep, and the Tibetan wolf. It is also the premier breeding ground in India for the vulnerable Black-necked Crane (Grus nigricollis) and Bar-headed Goose (Anser indicus).

8. Climate Cycles & Best Time to Visit

The travel season spans from June through late September. During these brief summer months, daytime temperatures reach a comfortable 14°C to 20°C under bright sunshine, though nighttime temperatures hover near freezing. July and August bring vibrant nomadic camp life and the annual Korzok Gustor monastic festival.

Winter (October through May) is an unimaginably harsh Arctic deep freeze, with temperatures plunging to between -35°C and -45°C. Tso Moriri freezes completely solid with ice over two metres thick. The Changpa nomads endure this extreme season inside insulated rebos warmed by burning dried yak dung.

9. Mountain Stays & Indigenous Food Culture

Accommodations in Changthang are concentrated in Korzok village (Tso Moriri) and Chumathang, consisting of comfortable seasonal tented camps, eco-cottages, and traditional family homestays. Homestays offer carpeted communal dining rooms heated by central bukhari stoves.

Dining in Changthang is hearty and high-energy: steaming bowls of thukpa, tsampa porridge, freshly made khambir bread, and unlimited cups of hot salted butter tea (gur-gur chai) that provide essential fats and hydration in the dry, cold air.
