The Hillary Step: Navigating the Most Iconic Obstacle on Mount Everest
For decades, the Hillary Step stood as the ultimate physical and psychological gatekeeper to the roof of the world. Located at an altitude of approximately 8,790 metres, this formidable rock face was the final technical challenge facing climbers before they could claim victory on the summit of Mount Everest. Named after Sir Edmund Hillary, who, along with Tenzing Norgay, first conquered it in 1953, the step has long been a symbol of the grit required for elite mountaineering.
However, recent geological shifts have changed the landscape of the mountain forever. Whether you are an aspiring climber or an armchair adventurer, understanding the history, the health risks, and the current state of the Hillary Step is essential for grasping the reality of modern high-altitude expeditions.
What Exactly is the Hillary Step?
The Hillary Step is a vertical rock wall located on the Southeast Ridge, halfway between the South Summit and the true summit of Everest. In its original state, it was a 12-metre (39-foot) wall of rock and ice that required precise technical climbing skills. At this extreme elevation, the high-altitude environment makes every movement feel like running a marathon while breathing through a straw.
Climbers must utilise fixed ropes and crampons to navigate this section. The difficulty isn’t just the incline; it is the fact that it sits firmly within the Death Zone, where oxygen levels are insufficient to sustain human life for long periods. You can learn more about the physiological effects of thin air via the NHS guide to altitude sickness.
The 2015 Transformation
The 2015 Nepal earthquake caused significant changes to the mountain’s topography. For several years, debate raged within the climbing community about whether the Hillary Step had collapsed. In 2017, British mountaineer Tim Mosedale confirmed that the step, as it was historically known, was gone. It has been replaced by a more manageable snow slope, though it remains a treacherous part of the summit ridge.
Comparing the Hillary Step: Then vs. Now
The transition from a vertical chimney to a snowy slope has altered the logistics of climbing Everest. Here is a comparison of the Hillary Step before and after the 2015 geological shifts:
| Feature | Pre-2015 Condition | Current Condition (Post-2015) |
|---|---|---|
| Physical Structure | Vertical 12m rock face | Sloping snow/ice ramp |
| Climbing Style | Technical rock/ice climbing | Steep snow trekking |
| Congestion Level | Extreme bottleneck (one-way) | Moderate bottleneck (wider path) |
| Risk Factor | Fall risk, exhaustion | Avalanche risk, overcrowding |
Health and Safety in the Death Zone
Reaching the Hillary Step is a feat of human endurance that pushes the body to its absolute limits. At nearly 8,800 metres, the body can no longer acclimatise. According to research published in Nature, the lack of oxygen leads to rapid cognitive decline and physical wasting.
Climbers must be vigilant for symptoms of:
- HACE (High Altitude Cerebral Edema): Swelling of the brain, often fatal if not treated by immediate descent.
- HAPE (High Altitude Pulmonary Edema): Fluid buildup in the lungs, which you can read about at the Mayo Clinic.
- Severe frostbite due to extreme cold and restricted blood flow.
To mitigate these risks, modern expeditions rely heavily on supplemental oxygen and the expertise of Sherpa guides. These local experts are the backbone of any Everest attempt, fixing lines and ensuring that climbers navigate the Khumbu Icefall and the summit ridge safely.

The Impact of Crowding on the Summit Ridge
Despite the physical changes to the Hillary Step, it remains a dangerous bottleneck. Because it is so close to the summit, many climbers arrive at this point simultaneously during “weather windows.” This leads to long queues where individuals may stand still for hours, depleting their limited oxygen supplies.
The National Geographic Society has frequently highlighted the environmental and safety impact of over-commercialisation on Everest. Managing these crowds is now one of the primary challenges for the Nepalese government and expedition organisers.
Essential Gear for the Final Push
- Down Suit: High-grade insulation to prevent hypothermia.
- Oxygen Mask and Regulator: To maintain consciousness in the Death Zone.
- Alpine Ice Axe: Essential for stability on the snow slope that replaced the rock face.
- Reliable Crampons: To ensure grip on the icy sections of the ridge.
The Legacy of Sir Edmund Hillary
While the physical rock may have crumbled, the legend of the Hillary Step lives on. It represents the “final hurdle” in any great endeavour. Sir Edmund Hillary’s commitment to the mountain extended beyond his climb; he spent much of his life building schools and hospitals for the Himalayan people through the Himalayan Trust. His legacy is a reminder that mountaineering is as much about the community as it is about the peak.
For those interested in the history of exploration, the Royal Geographical Society holds extensive archives on the early British Everest expeditions. Understanding the heritage of the mountain provides a deeper appreciation for the risks taken by those who stand atop the Hillary Step today.
Conclusion
The Hillary Step may no longer be the vertical chimney that Hillary and Tenzing famously scaled, but it remains a critical point of no return. Whether it is a rock face or a snow slope, the demands it places on the human spirit and body are unparalleled. By respecting the high-altitude environment and preparing for the risks of altitude sickness, climbers can continue to find meaning in this legendary passage.

Frequently Asked Questions (FAQs)
Has the Hillary Step completely disappeared?
Yes, most mountaineers and geological experts agree that the 12-metre rock wall known as the Hillary Step collapsed during the 2015 Nepal earthquake. It has been replaced by a steep snow slope, which is generally considered easier to climb but still poses significant risks due to ice and weather conditions.
Where is the Hillary Step located?
The Hillary Step is located on the Southeast Ridge of Mount Everest, situated between the South Summit and the main summit. It sits at an elevation of roughly 8,790 metres (28,839 feet) above sea level. You can view maps of the region on Britannica.
How long does it take to get past this section?
In ideal conditions, it can take 15 to 30 minutes. However, due to extreme oxygen levels and crowding, climbers often wait for hours in a queue. This delay increases the risk of exhaustion and altitude sickness. For health advice on physical exertion, visit Healthline.
What is the “Death Zone” on Everest?
The Death Zone refers to altitudes above 8,000 metres. At this height, there is not enough oxygen for humans to breathe without support. The Hillary Step is located deep within this zone, making it one of the most dangerous places on Earth. Learn more about oxygen and biology via ScienceDaily.
Can beginners climb the Hillary Step?
No. Climbing the summit ridge of Everest requires years of experience in technical climbing, glacier travel, and high-altitude endurance. Prospective climbers should consult organisations like the American Alpine Club for training resources and safety standards.
