Difficulty & Readiness Guide
Extremely difficult. Features complex, heavily crevassed glaciers and steep, dangerous ice-wall descents.
The Question
Preparation Required
Advanced
Prior Experience
Required: At least 2-3 moderate Himalayan treks (above 13,000ft).
Highly technical peak requiring physical and mental preparation.
At 51/100 on the ExpeditionDifficulty Scale, this is one of India's most demanding high-altitude crossings. Due to the remoteness, sustained altitude, and total daily effort, this crossing demands elite fitness and prior high-altitude experience.
Route Knowledge
Demanding glaciated pass crossing requiring sustained altitude endurance.
Physiological Demand
Expect long, exhausting days of sustained climbing at high intensity. Your cardiovascular system will be pushed to its absolute limit.
Significant time spent above 12,000ft. Expect shortness of breath and slower pacing.
Notable elevation gains and losses requiring good leg strength and joint resilience.
Comfortable pacing with good recovery options.
Well-defined, stable trails with no technical maneuvers required.
A completely broken, trackless route requiring intense scree navigation, rope-fixing on the pass, and jumping over active, open crevasses.
18,000 ft demands a painful pace. The ascent requires using Jumars on a fixed rope. Exhaustion is absolute.
Descending the Kalanag glacier heavily depends on snow conditions. If blue ice is exposed, it requires strict crampon walking and potentially rappelling down seracs.
Aggressive. You sleep at roughly 15,800 ft which offers massive HAPE generation potential. Evacuation is agonizingly slow.

Hazard Profile
Most injuries and failures on this trail can be avoided by making smarter decisions early on.
Pacing too fast out of Kyarkoti.
Assuming that once you crest the pass, the danger is over. The Kalanag descent is deadlier than the climb.
Crevasse falls on Kalanag glacier
Extreme Hypothermia
Avalanches on the Jhala side wall
AMS (Altitude Sickness)
Very high risk over 16,000 ft. Diamox is heavily advised. Any severe headache at Camp 1 requires immediate abortion.
Evacuation Route
Effectively manual. A breakdown on the glacier means your team must physically haul you down to Kyarkoti or Ruinsara before a helicopter can even safely attempt an extraction.
Solo Trekking
Extremely dangerous due to hidden crevasses on the Kalanag glacier.
Common Trail Ailments
๐ฅ Nearest ICU: AIIMS Rishikesh / Max Super Specialty Hospital, Dehradun
> Extraction from the summit or Kalanag glacier is purely manual. Helicopters cannot safely operate in the Dhumdhar drafts.
