The Kolahoi Glacier trek is a classic 2-day route from Pahalgam (or 1-day from Aru), following the Lidder River upstream through forest, alpine meadow, and moraine to the glacier terminus at around 3,800 m. The peak of Kolahoi (4,702 m) towers above the glacier, its north face permanently snow-covered. The views from the moraine above the glacier lake are among the finest mountain panoramas in the Kashmir Valley.
The route is straightforward to the glacier; no technical climbing is involved. Horses can carry gear and food from Aru to the base camp at Lidderwat. A guide is useful but not strictly necessary for the main route. The best season is June to September; the glacier is inaccessible from October to May.
