At a glance

Trip overview

We have designed this 60-day expedition for high-altitude mountaineers who aim to climb two of the world's highest peaks in a single season. Starting from Kathmandu, our route follows the classic Khumbu valley trek through Namche Bazaar and Tengboche before establishing our base camp for the long climbing and rotation phases on both Mount Everest and Lhotse.

This program is strictly suited for climbers who have already summited at least one 8,000 m peak and have extensive technical experience on ice, rock, and mixed alpine terrain. Our lead guides and Sherpa team manage all logistical operations directly, ensuring fixed ropes, oxygen supplies, and high camps are established efficiently under strict safety margins.

The physical demands are immense, requiring extended periods above 8,000 m on the South Col route and the Lhotse face. We maintain robust emergency rescue protocols and keep our team sizes optimized for close communication and support throughout the rotation and summit pushes.
