The Sharper Line Beside Everest
The fourth-highest mountain, sharing Everest's route to Camp III before splitting into a steeper, narrower line of its own — one that draws climbers who prefer the mountain to the crowd.
01 — DOSSIER FACTS
In Everest's shadow, Lhotse calls for a challenge.
Lhotse shares Everest's Base Camp, its Icefall, and its route to Camp III, then turns onto its own line and climbs the Lhotse Couloir — narrow, sustained, and steep enough that technique matters as much as altitude tolerance. Thamserku has organised 23 Lhotse expeditions since 1994, and the same Western Cwm logistics that carry our Everest teams carry Lhotse climbers in full. For many it is the connoisseur's eight-thousander: Everest's altitude category with a fraction of its traffic. For others it is half of the Everest–Lhotse double, two summits above 8,500m from a single Base Camp. Our work is to make sure the only thing you carry up is the climb itself. The Couloir does not reward distraction, and our work is to make sure there is none to bring.

07 — ROUTE
From Kathmandu to the summit. 9 points on the line.
Sharing the Western Cwm and Lhotse Face with Everest, the route diverges at Camp III toward the Geneva Spur and the Lhotse Couloir — a near-vertical passage that demands absolute technical confidence from all climbers.
Lobuche Peak (6,119m) summit ascent plus custom rotation schedules through Camps I, II, and III. The dual-summit structure is not generic — it is a deliberate physiological strategy designed around the demands of the Couloir above 8,000m.
Mid-May aligns with the same reduced jet-stream window as Everest. The Lhotse Couloir demands precise timing — we monitor multiple weather services and only commit when conditions are confirmed.
"Quiet answers, before you write to us."
Prior summit experience on a peak of 7,000m or above is recommended. The Lhotse Couloir demands technical confidence on steep ice — we assess each applicant's climbing resume before confirming participation.
Lhotse shares the approach and lower route but diverges at Camp III toward the Geneva Spur and the near-vertical Couloir. It is technically more demanding than Everest and sees far fewer climbers.
The Lobuche ascent is not a warm-up — it is a deliberate acclimatisation strategy designed around the physiological demands of the Lhotse Couloir above 8,000m.
4x 4L bottles per member and 3x 4L for Sherpa, with premium masks and regulators staged across camps. Additional oxygen available as an add-on.
