“One of the quietest Himalayan treks I've done. We barely saw another group, and the first view of the lake was worth every steep climb.”
Ghepan Lake Trek
Lahaul Valley, Pir Panjal Himalaya, Himachal Pradesh
“A wild Lahaul trek to a glowing turquoise glacial lake beneath hanging glaciers and rugged Himalayan ridges.”

Standout Experiences
- Reach one of Himachal Pradesh's most striking turquoise glacial lakes without trekking through crowded trails.
- Walk beneath hanging glaciers and across rugged moraine terrain that feels far more remote than most weekend Himalayan treks.
- Experience the quiet side of Lahaul, where you may meet more shepherds than fellow trekkers.
- Watch the lake change from deep blue to emerald as sunlight moves across the surrounding glaciers.
Overview
Updated 10 Aug 2026
- The Ghepan Lake Trek is one of Lahaul's best-kept secrets. Starting near Sissu on the Manali–Leh highway, the trail leaves the busy road behind almost immediately and enters a quiet valley where you'll hear rushing glacial streams far more often than other trekkers. The route passes shepherd camps, alpine meadows, loose moraines, and dramatic ridgelines before revealing the lake in an unforgettable burst of turquoise surrounded by snow and hanging glaciers.
- Unlike many popular Himalayan treks, Ghepan Lake still feels genuinely wild. There are no permanent tea houses or crowded campsites, and sections of the trail are faint enough that most trekkers hire a local guide. The reward is a landscape that changes every hour—green valley floors, rocky glacier terrain, wildflowers through summer, and finally the icy blue lake sitting beneath the towering Ghepan Glacier.
- The final approach is what makes this trek memorable. After climbing across rocky slopes and glacial debris, the valley suddenly opens to reveal a brilliantly coloured alpine lake framed by snowfields and sharp peaks. On clear mornings, the reflections in the water are so vivid that the lake almost looks unreal, making the long climb feel completely worthwhile.

- Report in Manali around late morning and drive for about 1–1.5 hours through the Atal Tunnel to Sissu, reaching by afternoon.
- The landscape changes dramatically after the tunnel as lush Kullu gives way to the dry mountains of Lahaul, with waterfalls tumbling beside the highway.
- Spend the evening checking gear, taking a short acclimatization walk around Sissu and resting well before the trek begins the next morning.

Technical Overview

Trail and Terrain
The trek follows ancient shepherd paths above the Sissu valley before entering wide alpine meadows. Expect narrow traverses, loose scree, boulder fields, occasional landslide patches and several glacier-fed stream crossings. The final approach to Ghepan Lake is mostly over moraine and rocky terrain with little tree cover, making trekking poles especially useful.
info
Altitude and Acclimatization
Although the highest point is only around 4,300 m, the trail gains altitude quickly from Sissu. Spending the first night at Gorduk and the second at Aliyas provides gradual acclimatization for most trekkers. Hydration, a steady pace and avoiding overexertion greatly reduce the chances of Acute Mountain Sickness.

Weather Conditions
Days are pleasantly cool through summer while mornings and evenings remain cold. Afternoon clouds frequently build over the surrounding peaks and brief showers are common during July and August. Strong winds are common near the lake and glacier viewpoint, so layered clothing is essential.
info
Water Availability
Water is plentiful until Aliyas Camp through natural streams. Beyond the last shepherd camp, reliable clean water becomes scarce, especially near the lake where glacial runoff often carries sediment. Carry at least two litres while heading to the lake and refill only at safe flowing sources.
When to Visit
