Difficulty & Readiness Guide
AD+/D- grade — India's most technical Ladakh trekking peak. Requires rope work, glacier skills, and prior high-altitude mountaineering.
Preparation Required
Elite
Prior Experience
Mandatory: Prior high-altitude trekking (16,000ft+) and basic technical knowledge.
Score Engine v3
Stamina
72/100
Based on average nightly altitude gain, highest campsite, and daily distance. Reflects how hard the average day feels.
Spike Day
50/100
Based on max altitude reached, summit day elevation gain, and summit day distance. Reflects the hardest single day.
An elite-level undertaking with extreme joint & muscle impact, cumulative fatigue, and altitude exposure. This route will push every dimension of your physical and mental endurance to the limit.
Physiological Demand
Steep, punishing ascents and descents that will heavily tax your knees, ankles, and overall joint stability.
Deep wilderness isolation and cumulative fatigue. The mental challenge of enduring days on end in harsh conditions is extreme.
Extreme high altitude exposure. Severe oxygen depletion requires careful acclimatization and peak cardiovascular health.
Expect long, exhausting days of sustained climbing at high intensity. Your cardiovascular system will be pushed to its absolute limit.
Rough, uneven trails with occasional scrambling or minor exposure.
Crux Section
Day 12 — Oxygen Peak
Highest exposure point at 20,997ft.
At 83/100, this expedition is a world-class physical challenge. Beyond the extreme endurance required, you are entering high-altitude technical terrain where standard trekking rules no longer apply.
Physical Challenge
Caution
Above 6,000m you will be operating at roughly 47% of sea-level oxygen. Every move is deliberate. Every clip on the fixed rope must be checked twice.
Steep ice wall of 55-65 degrees on the summit headwall. Requires full alpine technique.
Highly technical. Fixed ropes mandatory on the upper 400m. Guide required.
Requires rappelling the summit headwall. Not negotiable.
Prior experience on at least PD+ grade ice routes mandatory.
Highest exposure point at 20,997ft.
Deep 4,597ft descent will test joint stability.
Day 3 requires the highest sustained output.

Hydration
1.5L per km recommended
Loose Surface Sections
Most injuries and failures on this trail can be avoided by making smarter decisions early on.
Underestimating the technical difficulty vs KY2
Inadequate rope management
Fall on exposed knife-edge ridge
HACE above 18,000ft
Crevasse on glacier approach
Weather trap at ABC
AMS (Altitude Sickness)
Full rotation cycle required (carry to ABC, return to BC). Do not push to summit without prior acclimatization rotation.
Evacuation Route
Retreat to Base Camp, horse evacuation to Chilling, vehicle to Leh SNM Hospital.
Solo Trekking
Solo expeditions are strictly discouraged. The route involves technical glacier travel, steep snow faces, and knife-edge ridges requiring a roped team.
Common Trail Ailments
🏥 Nearest ICU: SNM Hospital, Leh
> Immediate vehicle evacuation back down to Keylong if AMS strikes at Base Camp.
