This route covers 60km return.It involves around 4,000m of cumulative elevation gain.
The route reaches roughly 4,800m at its highest point. Proper acclimatization is strongly advised for this high-altitude journey.
Technically, the Yading Nature Reserve (The Big Kora) standard trail is challenging. The primary difficulty is the sustained physical effort required or technical terrain features.
Overview
Technical Summary
The 'Big Kora' is an advanced outer circumambulation route rarely undertaken by independent hikers and subject to changing local regulations. Yading Nature Reserve, located in the Tibetan plateau of western Sichuan, is dominated by three sacred snow-capped peaks (Chenresig, Jambeyang, and Chanadorje).
The Tibetan Pilgrim Context. A major element of the trek is its nature as a sacred route. Hikers frequently note the powerful experience of crossing high passes alongside Tibetan nomads and pilgrims spinning prayer wheels.
Hazard Assessment
Most of the route remains between 3,800m and 4,800m, with multiple passes exceeding 4,700m (15,400ft). AMS, HACE, and HAPE are constant threats.
The weather on the plateau is notoriously sustained. Snowstorms can bury the passes in June, and the temperature drops below freezing every night.
Potential altitude-related conditions include AMS, HAPE, and HACE. Adequate acclimatization is essential.
The Expert Take
Success on this route requires balancing physical stamina with environmental awareness.Local conditions shift rapidly; always verify forecasts with regional authorities before moving to higher ground.
Stage Breakdowns
Enter the Park and Acclimatize
Take the tourist bus to Luorong Pasture (4,150m), do the day hike to Milk Lake (4,500m) and camp. (approx. 10km)
The Outer Kora Wilderness
Leave the boardwalks for the back-valleys. Cross Wisum Pass and other high passes, camping near glacial lakes. (approx. 10-15km per day)
Closing the Loop
Circumambulate Chanadorje peak, cross the final pass, and descend back to the park entrance or Muli. (approx. 10-15km per day)

Technical Profile
Vertical Ascent Profile
Constantly strenuous. The trek is a continuous cycle of struggling up massive, scree-covered 4,700m passes and dropping down into 4,000m glacial valleys. Every step is an effort due to the thin air.
Terrain Characteristics
Located in Sichuan (Garzê Tibetan Autonomous Prefecture), China.
The cumulative energy expenditure for Yading Nature Reserve (The Big Kora) represents a significant physical commitment. Success requires adequate preparation and moisture management.

Access & Logistics
Regulations
Regulations regarding independent trekking on the outer kora can change. Foreign visitors may be required to hire a registered local guide. Verify local permit status before arrival.
Seasonality
The window is incredibly brief. Late May/early June (for rhododendrons, though snow is still heavy) and September/October (crystal clear skies and golden autumn colors). July/August is the monsoon; hiking is very difficult and muddy.

Route Questions
Can I do a shorter version?
Yes. Comparison: Short vs Big Kora. Most visitors do the 'Short Kora'—a 1-day, 10km round trip hike from Luorong Pasture up boardwalks to Milk Lake (4,500m). It is crowded but highly scenic. The Big Kora is a 60-80km multi-day wilderness trek.
