The Kolahoi Glacier Trek is one of the most rewarding high-altitude adventures in the Kashmir Valley — a challenging approach to the base of Kolahoi Peak (5,425 m), the highest summit in the Kashmir Valley, through some of the most dramatic glacial terrain accessible by trekking. The route combines the rich scenery of the Lidder Valley with a demanding ascent to one of the largest glaciers reachable on foot in this region. For trekkers seeking something more demanding and less-visited than the popular Kashmir lake treks, the Kolahoi Glacier route is a genuinely exceptional choice.
About Kolahoi Peak and Glacier
Kolahoi (also spelled Kolahoi or Gwashbrari) is the highest peak in the Kashmir Valley at 5,425 m. Its glacier extends down the southern face into the Lidder Valley, feeding the river that eventually runs through Pahalgam. The glacier has been retreating in recent decades due to climate change — visiting now means seeing it before further significant reduction. The approach to the glacier base takes you through the Nafran Valley, a subsidiary gorge of the Lidder system that is dramatically beautiful and sees very few trekkers compared to the main Lidder route.

Route Overview and Itinerary
Day 1: Aru Village to Lidderwat (3,050 m) — 11 km, 4–5 hours
Begin at Aru village, 12 km from Pahalgam. The trail follows the Lidder River through lush valley scenery — birch and conifer forest, meadows, and mountain views. Lidderwat is a wide, beautiful campsite where the main Lidder Valley divides. Camp here. This first day is the same starting section as both the Tulian Lake and Tarsar Marsar treks.
Day 2: Lidderwat to Satlanjan (3,500 m) — 10 km, 4–5 hours
At Lidderwat, the trail turns into the Nafran Valley — a narrower, steeper, and far less-visited side valley. The terrain changes dramatically as you enter a gorge of dark rock walls and cascading streams. Satlanjan is a shepherds’ encampment at the valley’s widening — dramatic and wild.
Day 3: Satlanjan to Kolahoi Glacier Base (4,000–4,350 m) — 10 km, 5–6 hours
The approach to the glacier becomes increasingly rocky and the path less defined. Boulder fields and moraine replace the meadow sections of lower elevation. The glacier comes into view progressively as you navigate the upper Nafran Valley — a vast expanse of ice and rock with Kolahoi Peak rising above. The campsite near the glacier base is raw, cold, and spectacular.
Day 4: Glacier Exploration and Rest Day
A day to explore the glacier margins, photograph the seracs and ice formations, and acclimatise properly. This is serious mountaineering terrain above the camp — do not venture onto the glacier itself without crampons and rope, and never solo. The surrounding rock ridges offer excellent viewpoints.
Day 5–7: Return via Lidderwat to Aru
The return can follow the same route or, for those with experience, a more challenging variation can be arranged. Some itineraries connect the Kolahoi approach with the Tarsar Marsar route for a combined 10–12-day experience covering the full range of the Pahalgam trekking zone.
Best Time for the Kolahoi Glacier Trek
- July: The glacier is at maximum summer extent. Nafran Valley wildflowers are at peak. The approach above Lidderwat may still have some snow patches in early July.
- August: Optimal — all trail sections clear, weather at its most stable. Best month for combining Kolahoi with any Tarsar Marsar extension.
- September: Excellent. The glacier colours change in autumn light. Very quiet — you may have the entire upper Nafran Valley entirely to yourself.
Difficulty and Fitness Requirements
The Kolahoi Glacier Trek is rated Moderate to Difficult. The upper Nafran Valley terrain is more technical than standard Kashmir lake treks — boulder fields, moraine navigation, and a steep final approach to the glacier base require sure-footedness and good balance. The altitude gain is significant but spread over multiple days, allowing reasonable acclimatisation if you follow the itinerary properly. Prior trekking experience in high-altitude terrain is strongly recommended.
What Makes Kolahoi Different from Lake Treks
Most popular Kashmir treks are centred on alpine lakes — and they are extraordinary. The Kolahoi Glacier trek offers something fundamentally different: a raw glacial environment, the approach to a genuine mountaineering peak, and a landscape defined by ice, rock, and scale rather than water and meadow. For trekkers who find lake scenery beautiful but want something more austere and geologically dramatic, Kolahoi fills that need perfectly.
Combining Kolahoi with Tarsar Marsar
The proximity of the Kolahoi approach and the Tarsar Marsar route (both starting from Aru via Lidderwat) makes a combined trek one of the most rewarding extended Kashmir experiences available. A 10–12-day itinerary can visit the Kolahoi glacier base and both Tarsar and Marsar lakes in a single expedition — covering the full range of the Pahalgam high-altitude trekking zone. This combined route is ideal for experienced trekkers who want maximum return from a single Kashmir trip. Contact Trek in Kashmir for a customised combined itinerary.
How to Get There
Starting point is Aru Village, 12 km from Pahalgam, 96 km from Srinagar. See our complete transport guide from Srinagar to Kashmir trek starting points.
Permits
The Kolahoi Glacier approach passes through protected forest areas. Forest camping permits are required and your operator arranges these. Foreign nationals should check ILP requirements in advance — see our permits guide.
Frequently Asked Questions
Can I walk on the Kolahoi Glacier itself?
Not safely without mountaineering equipment (crampons, ice axe, rope) and a qualified mountain guide. The glacier surface involves crevasse risk and is not appropriate for trekkers without glacier travel experience and proper equipment. Viewing the glacier from the moraine and rock ridges above the snout provides extraordinary views without the technical risk.
Is Kolahoi Peak climbable by trekkers?
Kolahoi Peak (5,425 m) is a mountaineering objective requiring technical climbing skills, glacier equipment, ropes, and a registered mountaineering guide with an Indian Mountaineering Foundation-certified Himalayan expedition permit. It is not a trekking peak. Contact us separately if you are interested in a Kolahoi Peak climbing expedition — we can arrange appropriately qualified guiding.
How does Kolahoi compare to the Great Lakes Trek?
The Great Lakes Trek offers the most variety (7 lakes) and is the more accessible, well-defined experience. Kolahoi offers more raw, glacial drama and significantly more solitude. If you want iconic Kashmir and a proven classic, Great Lakes. If you want something more adventurous and less crowded with genuine glacier scenery, Kolahoi is the better choice.
