A demanding 14–16 day high‑altitude trek to Green Lake (4,935 m) in North Sikkim that follows old expedition routes to Kanchenjunga. Expect forested lower trails, alpine meadows, prolonged ascents, and enforced acclimatization days—best for experienced trekkers.

A cold wind cuts across a high moraine and the first view of Green Lake opens as a shallow, glassy basin rimmed with scree and snow—Kanchenjunga’s ridgeline daring you to keep climbing. Early mornings on this route deliver crisp air, scattered rhododendrons lower down, and the steady cadence of boots on rocky trail as camps appear like temporary villages beneath huge peaks.

Early mornings on this route deliver crisp air, scattered rhododendrons lower down, and the steady cadence of boots on rocky trail as camps appear like temporary villages beneath huge peaks.
The Green Lake area sits on routes used by pre‑war expeditions approaching Kanchenjunga and the Zemu Glacier; maps here are younger than the rocks—metamorphosed schists and granite pushed up by the Himalayan collision. Local Sikkimese villages, primarily in Lachen and nearby valleys, keep alpine yak herding, Buddhist monasteries, and mountain hospitality that supports multi‑day treks.
Expect long days of steady ascent, deliberate acclimatization (scheduled rest days at Jakthang and the Green Lake rim), and mixed terrain: forested trails, high alpine meadows, rocky moraines and short glacier approaches. Weather changes fast—sun at noon, snow at dusk—and water is available at springs but should be treated.
Practical guidance: train with long hikes and daypacks, bring a warm sleeping bag rated to -10°C, and break the approach into the 14–16 day itinerary to allow acclimatization. Hire an experienced local guide, carry layers for wind and sun, and plan travel through Gangtok or Lachen for permits and logistics. The real reward is the scale—the lake sits high enough that the silence feels like new air, and the mountains ask that you move respectfully and steadily in their company.
challenging.
15–16 days.
Should have good aerobic endurance, experience with multi‑day treks, and the ability to hike 4–7 hours daily at altitude.
Yes—North Sikkim requires permits issued through registered operators; guides typically handle paperwork in Gangtok or Lachen.
The itinerary reaches Green Lake at roughly 4,935 m (16,190 ft), with camps up to about 4,725 m on the route.
While not strictly mandatory, previous multi‑day trekking and familiarity with altitude symptoms is strongly recommended.
Post‑monsoon months (September–November) and spring (April–May) offer the most stable weather and clearer mountain views.
The approach routes through North Sikkim were used by early 20th‑century expeditions to Kanchenjunga and the Zemu Glacier when other approaches were closed.
This region falls under restricted access to protect fragile alpine ecosystems and local culture—travel with licensed operators, pack out waste, and avoid campfire impacts.
Adarsh Tours, Travels & Expeditions operates guided outdoor trips and adventures with an emphasis on safety, stewardship, and memorable experiences.
