Stok Kangri Trek: Altitude, Permits & What to Expect

Stok Kangri — 6,153 metres — is the summit most people mean when they say they want to climb a real mountain in Ladakh. It's not a technical climb in the alpinist sense. No ropes, no fixed lines, no special equipment beyond what a properly prepared mountaineer would carry. What it requires is solid acclimatisation, good fitness, the right gear, and an honest assessment of your experience at altitude before you leave Leh.

The peak sits directly above the Stok Valley, south of Leh. On a clear day you can see it from the city. That proximity is deceptive — it takes several days of approach and at least three to four nights of sleeping progressively higher to give your body a real chance of reaching the top without turning back halfway due to altitude illness.

The Route Overview

The standard approach starts from Stok village, reachable by road from Leh in roughly forty-five minutes. From the village, the route climbs through the Stok Valley — through agricultural fields first, then scrub and scree, then glacier. The total vertical gain from Stok village to the summit is substantial: the village sits below 3,500m and the summit is above 6,150m. That's not done in a day, and it shouldn't be attempted in a day.

A typical itinerary spans five to six days:

• Day 1–2 in Leh — acclimatisation only; no major hiking
• Day 3 — Leh to Stok village, then walk to lower base camp or first high camp (approximately 4,400m)
• Day 4 — Acclimatisation hike higher, return to camp; or move to base camp (~4,900m)
• Day 5 — Summit push, typically departing well before dawn (2–3 am) to reach the top before conditions deteriorate midday
• Day 6 — Descent to Stok and return to Leh

Some trekkers add an extra acclimatisation day at base camp — particularly those who struggled at altitude during their Leh rest days. That extra day is almost always worth it.

Altitude Profile and Physical Reality

The altitude profile is what separates Stok Kangri from most Ladakh treks. The summit at 6,153m is not base-camp altitude — it is well into the zone where the body is working hard simply to sustain basic function. Even at base camp around 4,900m, sleep will be disrupted and appetite reduced. The summit push involves several hours of climbing at very high altitude in cold, often windy conditions, with a return the same day.

Location	Approximate altitude
Leh city	3,524m
Stok village	~3,400m
High camp / base camp	~4,900m
Stok La pass (en route)	~5,000m+
Summit — Stok Kangri	6,153m

At 6,000m, oxygen availability is roughly half that at sea level. Your pace slows dramatically. Many people find the final few hundred metres — particularly the glacier and the last steep section — significantly harder than the physical distance suggests. Rest-step technique, where you pause between each uphill step to let your breathing recover, is not optional at this altitude. It is how you move.

The summit push is typically done in cold darkness. By the time you're above 5,500m, the world is frozen and very still. Some climbers find the combination of cold, altitude, and effort more than they bargained for. Turning back from the summit, once it is clear the body isn't cooperating, is the right call — not a failure.

Permits

Stok Kangri sits within the Hemis National Park, and climbing it requires permits — both the national park entry fee and, depending on current regulations, a separate mountaineering permit. The permit situation has changed over the years: the peak was temporarily closed at one point due to environmental concerns about glacial impact from heavy foot traffic, and a restricted annual quota system has been introduced since.

Before making any firm plans, confirm the current permit status and quota availability with a registered mountaineering or trekking agent in Leh. This is not bureaucratic caution — it is essential planning. You cannot turn up expecting to begin the ascent without valid permits, and quota slots can fill early in the season.

Foreign nationals should also ensure their India visa allows travel to Ladakh — and review the Protected Area Permit requirements for restricted zones, confirming with a local agent whether Stok Kangri's approach route currently falls within any PAP area.

What You Need to Carry

This is not a day hike where light packing is a virtue. The gear list for a genuine 6,000m attempt is specific:

• Sleeping bag — rated to at least -20°C comfort, not just lower limit
• Crampons — the upper section of the route involves glacier; grip is non-negotiable
• Ice axe — for self-arrest on the steeper final slope; only useful if you know how to use it
• Trekking poles — essential for descent, when tired legs and icy terrain become a dangerous combination
• Warm layers — a summit attempt at 3 am at 6,000m means temperatures well below freezing; windproof outer shell, insulated mid-layer, thermal base
• Headtorch with spare batteries — the summit push is done in darkness; batteries drain fast in cold
• Pulse oximeter — monitor SpO2 throughout; know your baseline from your Leh days
• High-calorie snacks — appetite suppresses at altitude; force yourself to eat anyway

The altitude first aid kit article covers the medical essentials — carry all of it, and ensure your guide or partner knows where it is and how to use it.

Fitness and Training

Stok Kangri is hard. Not technically hard — but physiologically and physically hard. People who arrive in reasonable shape but have never hiked for six to eight hours on consecutive days at altitude frequently underperform on the summit day. The fitness preparation guide covers the foundations; for Stok specifically, add:

• Sustained uphill hiking with a loaded pack (10–12kg) on multiple consecutive days
• Cardio training that maintains elevated heart rate for two or more hours without stopping
• Practice with crampons on any incline available — even on a gentle snow slope — before attempting the summit glacier
• Cold exposure if possible — spending time outdoors in cold conditions acclimates the body to functioning when chilled

Guided vs. Independent

Independent ascents of Stok Kangri are possible for experienced mountaineers with glacier travel skills. For most people, a guide is not optional — it is the difference between a summit bid managed by someone who reads conditions and knows the retreat protocol, and a solo assessment made at 5,800m with impaired judgement from altitude.

A local guide from Leh also handles the permit logistics, knows the route conditions that season, and can make the call to turn back without needing to argue the point. That authority is worth paying for. Compare the Markha Valley trek — where independent is genuinely viable — with Stok Kangri, where the stakes of a wrong decision are considerably higher.

Best Season

July through September. July and August offer the most stable weather windows, although afternoon thunderstorms are possible and summit days should target early morning completion. September is colder but often clearer — and the mountain is quieter. After early October, the route becomes reliably dangerous and is essentially closed for the season.
