Goecha La
The classic viewpoint trek for Kanchenjunga, the world's third-highest peak. Long, remote, and permit-heavy — Sikkim requires a registered guide.
Fly the route in 3D
Real SRTM terrain, with the trail colored by each night’s AMS risk — watch where Goecha La starts pushing your body too fast.
Where you’ll sleep, on real terrain
The elevation profile traces the full climb and descent; tap a camp on the map and the SpO₂ gauge and safety numbers follow.
Reconstructed from real per-day distance, ascent and camp altitudes. The line between points is a straight approximation — not a surveyed terrain profile.
Best months
Curated season (Mar–May, Oct–Nov)— off-months reasoned from the region’s monsoon and winter.
Stage by stage
Distances are approximate operator-standard figures. Times are computed— Naismith’s rule (pace + climb + descent) slowed for altitude, for a fit trekker with breaks — not copied from brochures. Plan generously; groups move at the pace of their slowest member.
Night by night, stop by stop
Each stop is where you sleep — the altitude that drives acclimatisation. Exact camps and per-day distances vary by operator; the safety flags are computed from this profile.

Sold as "Difficult"; our numbers put it at Difficult. Broadly consistent.
Overnight lows lapse-adjusted to the high camp (~4200 m).
Sikkim: protected-area treks need a registered operator and, for foreigners, a Protected Area Permit.
Long and slow: descend over multiple days to Yuksom; your registered guide arranges pony/porter evacuation. Plan conservatively.
Approximate planning info — confirm with your operator. HAPE/HACE signs = descend immediately.
- •Long summit-view day with a pre-dawn start
- •Remote — evacuation is slow
- •Leeches lower down in monsoon fringe
On the trail
Necessary preparations
Fitness
- Serious base needed: 5 km under 30 min, weekly long hikes with a loaded pack; train 8–12 weeks out.
- Expect ~9 km of walking a day — train on stairs and inclines, not just flat ground.
- Do a few hikes carrying your actual daypack weight so your legs and shoulders are used to it.
Acclimatisation & health
- Know the AMS golden rules: don't ascend with symptoms; if worse, descend; HAPE/HACE = descend now.
- Carry a pulse oximeter and take a daily resting reading — a falling trend that doesn't recover means stop.
- Discuss acetazolamide (Diamox) with a doctor before you go — Shikhar never prescribes medication.
- This profile ascends fast (AMS: high) — build in a spare acclimatisation day if you can.
- Stay hydrated (3–4 L/day), eat well even without appetite, and avoid alcohol at altitude.
- Carry a personal first-aid kit; tell your operator about any medical conditions in advance.
Gear & clothing
- Layering system: moisture-wicking base, fleece/down mid, waterproof-breathable shell (jacket + pants).
- Broken-in waterproof trekking boots with ankle support + 3–4 pairs of wool/synthetic socks.
- 40–55 L backpack with rain cover; a 20 L daypack if porters carry the main load.
- 3-season sleeping bag rated to at least −5 °C; a liner adds warmth cheaply.
- Trekking poles, sun hat, and warm hat + gloves for cold camps.
- UV protection: category-4 glacier sunglasses, SPF 50+, lip balm — UV is brutal at altitude and on snow.
- Headlamp (+ spare batteries), 1 L insulated bottle, and a power bank (cold drains batteries fast).
Documents & permits
- Government photo ID (original + several photocopies) and passport photos for permits.
- Line/area permit (ILP for Indians, PAP for foreigners) — see the permit navigator for this state.
- Forest/national-park entry & camping permit — often arranged at the roadhead or by your operator.
- A registered guide/operator is mandatory here — book before you arrive; independent trekking isn't allowed.
- Travel + trek insurance that explicitly covers high-altitude trekking and helicopter evacuation.
- Emergency-contact card: family contact, blood group, allergies, and your day-by-day itinerary.
Trekker experiences
Illustrative trail notes — representative composites of what trekkers commonly report on this route, not reviews from named individuals. Verify specifics with your operator.
“Ten days, remote, and permit-heavy — but standing before Kanchenjunga at dawn from the viewpoint is a lifetime memory. The Dzongri acclimatisation day is not optional; take it seriously.”
“You must go through a registered operator in Sikkim, which actually made logistics smooth. Cold and long summit-view morning start — layer up. Evacuation would be slow out here, so pace yourself.”
