Lobuche East Peak Climb

The route is rated 8 out of 10 — a level between Island Peak (8/10) and Mera (7/10) — and is not suitable for those without prior mountaineering experience.

What you need to be able to do

• Walk 6–10 hours per day with a day pack of 7–10 kg over varied terrain for six consecutive days (the EBC trek).

• Gain 700–800 metres of elevation in 3–4 hours on the summit push section (High Camp → summit).

• Sleep at altitudes of 4,500–5,400 metres for five consecutive nights.

• Move confidently in crampons on a firn slope of up to 45° inclination.

• Operate a jumar on fixed ropes: tie a figure-of-eight, rig an abseil, travel roped in a team.

• Spend the night in a −15 °C sleeping bag with tent temperatures of −10 to −15 °C at High Camp.

About altitude sickness

At 5,600 m the partial pressure of oxygen is approximately 48% of sea level; at the summit approximately 45%. Symptoms of mild altitude sickness at these elevations are nearly universal (disturbed sleep, headache, reduced appetite) and are not grounds for retreat. Moderate symptoms (vomiting, persistent severe headache, shortness of breath at rest, impaired coordination) are grounds for immediate descent. HACE and HAPE at 5,400–6,100 m occur in 1–3% of participants on commercial expeditions without adequate acclimatisation; our 17-day schedule with two dedicated acclimatisation days reduces that figure to <1% based on our own statistics (44 groups over 5 seasons).

What we use for monitoring

• Daily SpO2 measurement with a portable pulse oximeter (normal range at 5,000 m: 75–85% at rest; below 70% at rest or complaints of breathlessness — grounds for evacuation).

• Lake Louise Score (standardised AMS scale) at 4,500 m and above.

• Diamox 125 mg twice daily as prophylaxis — at your physician's discretion; we do not prescribe.

• Dexamethasone 8 mg IM in the expedition medical kit for acute HACE.

• Nifedipine 30 mg in the medical kit for HAPE.

• 1 oxygen cylinder with mask per group for emergency support during evacuation.

Who this route is not suitable for

• Those without prior experience above 5,000 m.

• Those without experience using crampons, ice axe, and fixed ropes (minimum: a 1–2 week mountaineering course within 6 months before departure).

• Pregnant persons.

• Those with uncontrolled hypertension, coronary artery disease, or severe asthma.

• Age 60+: individual consultation with a physician required, not a prohibition.

What we recommend doing in advance

• A mountaineering course or summit of 4,000–5,000 m within 12 months before departure (Elbrus, Kazbek, Orizaba, Mera, Island).

• Cardio training 4–5 times per week (running, cycling, skiing) for 60–90 minutes, starting 3–4 months before departure.

• Leg and core strength work twice a week.

• ECG, full blood count and metabolic panel, GP consultation specifying planned altitude of 6,100 m — 4–6 weeks before departure.

Equipment falls into four categories. Mountaineering gear can be partially rented in Kathmandu (see below).

Mountaineering — critical

• Double mountaineering boots at the level of La Sportiva Nepal Cube GTX, Scarpa Phantom 6000, or equivalent. Single 'trekking' boots are unsuitable for the summit push. Available to rent in Kathmandu ($5–8/day).

• Crampons — step-in or semi-automatic, compatible with your boots. Rental $1–2/day.

• Ice axe 60–70 cm. Rental $1–2/day.

• Mountaineering harness with load-bearing loops for jumar and belay device.

• Jumar + belay/rappel device (figure-of-eight or Reverso) + 3 locking carabiners + 2 HMS locking carabiners.

• Mountaineering sling 120 cm × 2 for self-belay.

• Mountaineering helmet.

• Gaiters to protect boots from snow.

• Down suit or warm down jacket + insulated trousers for summit day.

Warm clothing — critical

• Sleeping bag rated to −20 °C comfort (not 'extreme'). High Camp temperatures reach −15 °C inside the tent at night.

• Merino wool base layers — 2 sets.

• Mid-layer fleece (heavyweight fleece jacket).

• Hardshell jacket + trousers (wind and waterproof).

• Down mittens + fleece gloves + thin liner gloves (3 layers).

• Balaclava + fleece hat + buff.

• UV category 4 mountaineering goggles — mandatory. On snow above 5,500 m, snow blindness can occur within 1–2 hours without them.

Trekking section — important

• Well broken-in trekking boots (for the lower section of the route to base camp).

• Trekking socks: 3 pairs thin + 2 pairs warm.

• Telescopic trekking poles.

• Summit pack 30–45 L + duffel bag 80–90 L for the porter.

• Headlamp + 2 spare sets of batteries.

Personal

• Personal medical kit: Diamox (after consultation with your physician), ibuprofen/paracetamol, anti-diarrhoeal medication, oral rehydration salts, blister plasters, elastic bandage, your regular medications with ×2 supply.

• SPF 50 sunscreen for face and lips.

• 1 L water bottle + 1 L thermos.

• Power bank 20,000+ mAh (charging in lodges is paid; none available at base camp).

• Wet wipes, toilet paper.

• Documents in a dry bag.

• A few small-denomination dollar bills.

Rental in Kathmandu: double boots, crampons, ice axe, harness, jumar, figure-of-eight, −20 °C sleeping bag — all available in Thamel for $15–30/day for a full kit. Quality varies; the guide assists with selection. If you plan 2+ expeditions in your career, bringing your own gear is more cost-effective.
