What Makes Auden’s Col So Popular?
Auden’s Col is one of the most iconic and sought-after high-altitude crossings in the Garhwal Himalayas. Connecting the Rudugaira Valley and Bhilangana Valley, it links Gangotri to Kedarnath via Khatling Glacier.
Highlights of Auden’s Col Trek:
- Starts from the holy town of Gangotri.
- Merges the spiritual aura of Gangotri and Kedarnath valleys.
- Offers close views of peaks like Gangotri III, Jogin I and II, and Bhagirathi massif.
- Crosses massive crevasses of the Khatling glacier.
- Involves a combination of trekking and mountaineering.
While Auden’s Col is undoubtedly thrilling, its popularity comes with some caveats:
- Heavily trafficked in peak season.
- Terrain near Khatling Glacier can be dangerously unstable.
- Risk of crevasse falls is high.
It’s often ranked among the top 10 difficult treks in India, and sometimes even compared with the most dangerous trek in India due to the technicality of glacier crossings and high-altitude hazards.
Why Choose Traill’s Pass Over Auden’s Col?
1. More Remote and Less Explored
Unlike Auden’s Col, Traill’s Pass is a lesser-known gem tucked deep in the Kumaon Himalayas. This means fewer crowds, more solitude, and a stronger sense of true Himalayan wilderness. If you’re looking for less explored treks in Uttarakhand, this is your go-to.
2. Historic and Cultural Significance
Traill’s Pass was named after G.W. Traill, the first British Commissioner of Kumaon, who crossed it in 1830. The route holds historical value and cultural connections with local communities like the Bhotiyas.
3. Massive Himalayan Views
Traill’s offers jaw-dropping views of major peaks such as Nanda Devi East, Nanda Kot, and Hardeol. The scale and rawness of the landscape often surpass that of Auden’s Col.
4. Technical Yet Rewarding
While both treks require mountaineering gear and experience, Traill’s Pass challenges you with vertical ice walls, narrow rock gullies, and crevassed glaciers, making the summit a genuinely earned achievement. It is one of the tough treks in Uttarakhand that is still relatively untouched.

5. Authentic Off-the-Beaten Experience
For trekkers who value remoteness, no cell signal, basic trails, and camping under starlit skies far from civilization, Traill’s Pass is the ultimate Himalayan escape. A true gem among difficult Himalayan treks in India.
