The Khumbu Icefall is located on the southern side of Mount Everest in Nepal. It sits between Everest Base Camp and Camp I, marking the first significant challenge for climbers heading up the mountain. It is located at an elevation of about 5,486 meters (18,000 feet) above sea level, nestled within the massive Khumbu Glacier. Additionally, this area is remote and incredibly challenging, with climbers relying heavily on the expertise of Sherpas to guide them safely through the Icefall’s many dangers.

The Khumbu Icefall stretches about 2 kilometres (1.24 miles) from Everest Base Camp to Camp I. Although it’s not a long distance, the dangerous terrain makes it one of the most challenging parts of the climb.

It is practically impossible to avoid this section on the South Col route. Many climbers who want to conquer Mount Everest from the south side must cross it. Although there are alternative routes on the Northern side of the mountain or opt for Everest Base Camp Helicopter Tour, those come with their own challenges.

Crossing the Icefall can take about 3-6 hours, depending on the conditions and the level of experience. Normally, climbers start early in the morning to avoid the risk of melting ice due to sunlight.

The movement of the Khumbu Glacier from the Western Cwm area created the Khumbu Icefall. As the glacier moves and the slope changes, the ice breaks, forming large crevasses and seracs. The fact that the glaciers are constantly shifting ensures that the Icefall is ever-changing, creating a maze difficult to navigate.

The best time to cross the Icefall is early in the morning when the weather is colder and the ice is still stable. So, the ideal seasons to cross this region are spring (March-May) and autumn (September-November).
