Lhotse Expedition – World's 4th Highest Peak - 8516 M - 45 Days

Join a professionally guided Lhotse Expedition via the Everest South Col Route, climbing the world’s fourth-highest mountain at 8,516 m / 27,940 ft. This expedition follows the same legendary approach as Mount Everest up to Camp IV, before diverging into the steep and technical Lhotse Couloir for the summit ascent.  

Introduction

Lhotse, towering at 8,516 meters, stands immediately south of Mount Everest and is connected to it by the South Col. Despite sharing much of its approach with Everest, Lhotse presents a distinctly more technical summit climb, requiring sustained ice and snow climbing at extreme altitude.

Our Lhotse Expedition follows the classic Everest South Col route through the Khumbu Valley, allowing for proven acclimatization and established logistics. The journey begins with a flight to Lukla and a gradual trek through iconic Sherpa settlements including Namche Bazaar, Tengboche, and Dingboche, before reaching Everest Base Camp beneath the Khumbu Icefall.

By following the same acclimatization strategy as Everest expeditions—multiple staged rotations through Camps I, II, and III—climbers are optimally prepared for high-altitude performance. However, unlike Everest, the final ascent of Lhotse does not follow a long ridge but instead climbs the Lhotse Couloir, a steep and sustained gully demanding strong technical ability, efficient rope work, and precise timing.

This expedition is ideal for climbers who already possess 7000–8000 meter experience and are seeking a more technical, less-crowded alternative to Everest, while still benefiting from the safety and infrastructure of the South Col route.

Lhotse South Col Route & High Camps

The Lhotse Expedition shares identical logistics and route infrastructure with Everest expeditions up to Camp IV (South Col). This allows climbers to take advantage of fixed ropes, professionally established camps, and coordinated Icefall management while pursuing a more demanding summit objective.  

Khumbu Icefall: The Gateway to Everest’s Upper Camps

The ascent begins with repeated crossings of the Khumbu Icefall, one of the most technical and unstable sections of the climb. Ice towers, deep crevasses, and shifting seracs require careful movement along fixed ladders and ropes installed by the Icefall Doctors.

Crossings are timed during early morning hours to minimize objective risk caused by ice movement. For Lhotse climbers, efficient Icefall travel is essential, as multiple rotations are required for acclimatization and load carries.

Camp I (5,945 m) | Gateway to the Western Cwm

Camp I is located on a broad snowfield at the top of the Khumbu Icefall. It serves primarily as a transition camp and acclimatization point. Most climbers pass through Camp I without extended stays, continuing onward into the Western Cwm when conditions allow.

Camp II (6,400 m) | Advanced Base Camp (ABC)

Camp II, often referred to as Advanced Base Camp (ABC), serves as the main operational hub above Base Camp. Sheltered by surrounding peaks, it is equipped with larger dining and kitchen tents, communication systems, and multiple sleeping tents.

This camp plays a critical role during acclimatization rotations and acts as the staging point for establishing Camp III on the Lhotse Face and Camp IV on the South Col. Due to its relatively protected position, climbers can spend longer periods here compared to higher camps.

Camp III (7,164 m) | Lhotse Face High Camp

To reach Camp III, climbers ascend the Lhotse Face, a steep wall of hard ice and snow rising directly above the Western Cwm. Fixed ropes are essential, and progress requires strong crampon technique, endurance, and careful pacing.

Camp III is established on narrow ledges cut directly into the ice. Tents are securely anchored and typically used only for short stays, as the exposed location makes prolonged habitation impractical. Many Sherpas and strong climbers carry loads directly from Camp II to Camp IV to reduce time spent on the Lhotse Face.

Camp IV – South Col (7,900 m) | High Camp in the Death Zone

Camp IV, also known as High Camp, is located on the South Col—a high, windswept saddle between Everest and Lhotse. This marks the climbers’ first overnight stay in the Death Zone, where the body can no longer acclimatize.

Supplemental oxygen is used for both sleeping and climbing at this altitude. Camp IV is established only when a favorable summit window is confirmed, as prolonged exposure significantly increases risk. This camp serves as the final staging point before the summit attempt.

Lhotse Summit (8,516 m / 27,940 ft) | The Lhotse Couloir

From Camp IV on the South Col, the route diverges from the Everest climbing line and traverses toward the base of the Lhotse Couloir, a steep and narrow gully leading directly to the summit. The ascent involves sustained snow and ice climbing at angles of approximately 50–55 degrees, with fixed ropes used throughout. Unlike Everest’s Southeast Ridge, there is no extended ridge walking; climbers must maintain continuous technical movement at extreme altitude. With limited natural resting points and consistently steep terrain, this section is widely regarded as more technically demanding than Everest’s summit ridge, requiring strong ice-climbing skills, efficient rope management, and high physical commitment.

The summit push begins late at night or in the early morning hours from Camp IV. Climbers ascend the Lhotse Couloir under headlamp, reaching the summit ridge shortly before dawn under favorable conditions. Standing at 8,516 m / 27,940 ft, the summit of Lhotse offers dramatic views across Everest, Makalu, and the vast Tibetan Plateau. Due to the extreme altitude and exposure, time on the summit is kept brief before a careful and controlled descent back to Camp IV or, conditions permitting, onward to Camp III.
