China’s Mount Everest Tourism Surge Sparks Environmental Concerns

China's Everest Obsession: Revisiting Mallory’s Route as Tourism and Climate Change Recast the Himalayas

Once standing as an unclimbable frontier, Mount Everest today is both an adventurer’s prize and a symbol of environmental change. As the world marks a century since George Mallory and Andrew Irvine’s disappearance during their 1924 summit attempt, Everest is experiencing record-breaking crowds and environmental shifts. Here’s an inside look at how travel, tourism, and climate change are transforming the world's highest peak—and what that means for modern-day visitors.

Everest Climbing Season: A Brief Opportunity with Big Crowds

Each year, the prime window for scaling Everest falls between late May and early June, when a fleeting calm interrupts otherwise punishing winter and monsoon conditions. Even then, only a handful of days present ideal weather for summiting. This narrow time frame creates bottlenecks, especially at infamous spots like the Hillary Step, and has led to images of long lines of climbers angling for a once-in-a-lifetime view.

While only 150 climbers reached the summit in the three decades after the first ascent by Edmund Hillary and Tenzing Norgay in 1953, interest has soared in recent years. A record 877 ascents were recorded in 2019, and 2024 nearly matched that number. The result: Everest is no longer the domain of elite mountaineers, but a bucket-list goal within reach for hundreds each year.

Changing Landscape: Tourism’s Impact on Everest

At Everest’s southern base camp in Nepal, facilities have multiplied—coffee shops, equipment outfitters, and party tents now line the glacier where just a few expeditions once camped. The northern, Tibetan side, administered by China, has seen even faster growth. Today, tarmacked roads connect Lhasa and Shigatse directly to Rongbuk Base Camp, now a tented tourist village hosting as many as 3,000 visitors daily in peak season.

In the past two decades, annual visitors crossing into Tibet’s Qomolangma region have soared to more than half a million—most traveling from within China. Many tourists take speedy tour packages, with short acclimatization stages and supplemental oxygen, combining Everest with cultural stops in nearby cities.

For car lovers, the 5,000-kilometer Route 318—connecting Shanghai with the foot of Everest—has become a signature drive, bringing a new kind of “road trip” tourism to the Himalayas.

Retracing the Footsteps of Mallory and Early British Expeditions

To appreciate Everest’s transformation, we retraced the earliest British reconnaissance routes in Tibet, using archival journals and vintage photographs as guides. June 2024 marked exactly 100 years since Mallory and Irvine’s fateful summit bid, giving added meaning to the journey.

Early expeditions, blocked from Nepal by closed borders, set up camp along both the northern Rongbuk Valley and the eastern approach via Kama Valley. Their century-old records reveal a landscape with far more extensive glaciers and untouched meadows. Scientific studies estimate glaciers in the Everest area have shrunk by more than a quarter since the 1970s, with stark before-and-after photo evidence at passes such as Langma.

Modern Comforts—and Environmental Costs

Today’s visitors to Rongbuk camp can expect heated and oxygenated tents converted from traditional yak hair shelters, souvenir stalls, and even a post office billed as the world’s highest. While improvements in infrastructure offer travelers previously unthinkable comfort and accessibility, they come with costs: restricted access beyond the monastery and boardwalks, crowding, and pressure on the fragile Tibetan plateau ecosystem.

In response to environmental danger, authorities in Tibet introduced mandatory electric buses in 2019, shuttling tourists from the town of Tashi Dzom to base camp. Future plans include a new park hub closer to the highway, aiming to ease congestion and limit vehicles on the mountain.

Meanwhile, herders, once the mainstay of the local economy, have seen livestock numbers fall as national programs promote conservation and offer compensation for reduced grazing.

Kama Valley: Everest’s Pristine Eastern Gateway

While not as heavily trafficked as the Khumbu (Nepal) or Rongbuk (Tibet) base camps, the eastern Kama Valley offers trekkers some of the most spectacular vistas of Everest’s rarely seen faces. The journey from Kharta follows a river gorge into alpine meadows abloom with rhododendrons and azaleas, overlooked by Makalu—the Himalaya’s fifth-tallest peak.

Accommodation is basic but atmospheric: a farmhouse once used by British explorers now houses a Tibetan family, who welcome visitors interested in stepping back through mountaineering history. In summer, high-altitude yak herders share the trails with hikers, and prayer flags flutter above passes still considered sacred.

The valley’s biodiversity remains rich, but now faces increasing impact from trekking groups, particularly issues with waste management.

Climate Change: The Mountain in Retreat

Across both the north and east of Everest, glacier retreat is unmistakable. Historic photos taken near the head of Kama Valley document deep, blue tongues of ice that today are replaced by rocky moraines, small lakes, and lunar landscapes. Avalanches still rumble down mighty cliffs, reminding visitors that Everest’s terrain is always in flux—and that dangers for climbers are ever-present.

Even non-climbers can witness climate change firsthand. The iconic Kangshung glacier has receded dramatically, with its flow now diverted from the underground ice caverns described in expedition journals a century ago.

Conservation, Culture, and Local Communities

The Qomolangma National Nature Preserve, which includes Chinese Everest, is expected to be upgraded to full national park status. This could usher in increased environmental management to cope with booming visitor numbers. Yet, despite the economic growth that tourism brings, concerns remain about preserving Everest’s layered cultural heritage and the spiritual significance the mountain holds for Tibetan and Sherpa communities.

While China tightly regulates climbs—avoiding permit fees in 2024 and focusing on climber qualifications—Nepal’s side sees larger crowds, higher accident rates, and greater reliance on international tourism. The Tibetan side had no fatalities in 2024, while eight lives were lost on the Nepalese slopes.

Travel Tips for Everest Visitors

• Access: The north side of Everest is easier to reach by road via Tibet. The south (Nepal) side requires multiple flights, treks, and permits.
• Season: Peak months are April to June and September to November. The best weather is in late spring.
• Acclimatization: High altitude makes slow ascent essential. Carrying oxygen or using supplemental canisters is common on the Tibetan side.
• Permits: Chinese regulation can change; commercial climbing is tightly controlled and may require proof of previous high-altitude summits.
• Eco-Ethics: Practice ‘Leave No Trace’ principles, and use guided services that commit to responsible waste management.
• Explore Beyond the Base Camp: For those seeking less-crowded Himalayan trails, trekking in the Kama Valley or to Rongbuk Monastery offers historical and scenic rewards without summit ambitions.

The Future of Everest: Finding Balance

As Everest’s legendary allure endures, so too do the challenges posed by mass tourism and warming temperatures. Travelers and climbers are urged to approach the mountain with not only respect for its dangers and beauty, but for the communities and cultures that call it home. A visit to Everest is an adventure—one now shaped by history, human impact, and the pressing realities of climate change.

Every trek, every summit, and every photograph becomes part of the evolving Everest story. For those planning their own Himalayan trip, remembering both the fragile environment and the sacred traditions rooted here is vital for ensuring this extraordinary region stands tall for generations to come.
