Mount Cho Oyu, the world’s sixth-highest peak at 8,188 meters (26,864 ft), sits on the Nepal–Tibet border and is famously known as the “Turquoise Goddess.” Often considered one of the more accessible 8,000-meter mountains, it attracts climbers who want to experience true high-altitude mountaineering without the extreme technical challenges found on many other Himalayan giants.
Climbers who prefer to stay on the Nepal side often choose the Manaslu Expedition 2026 as their first 8,000m peak similar accessibility, no Tibet permit required, and starting at $18,800."
Summit 8000 provides you a golden opportunity to climb this peak if you are a mountain climber and want to climb the peak above 8000 meters but is afraid of the technical difficulty to climb the peaks such as the Mount Everest, Mount Annapurna or any other peaks.
The peak is located between the border of the Nepal and Tibet and be climbed from the both countries. It’s the more accessible high altitude climb which gives the perfect views of the Everest, Lhotse, and other Himalayan giants from its summit.
Its glaciers are extensive but relatively gentle and the routes leading to its summit top is Himalayan serenity, where you will witness golden sunrises over jagged peaks, encounter unique alpine wildlife, and engage with the welcoming local culture.
The mountain’s appeal lies in its combination of stunning beauty, high-altitude adventure, and achievable summit for experienced trekkers and mountaineers alike.
Cho Oyu Climbing peak route starts from the Nepal side which is fly from the Kathmandu to Lukla and from there to the Nyalam village in Khumbu region. From the Nyalam village you hike to the base camp at an altitude of the 5,700 meters.
Following the series you will climb to the Camp – I at an altitude of 6400 meters and from there to the camp – II at an altitude of 7000 meters and from the Camp II you will have a rapid ascend to the summit at 8818 meters.
The base camps are located over the glacial slopes and ridge from where you can acclimatize and climb gradually to the extreme altitude reducing the risk of the high-altitude sickness.
The climb is not technically difficult and but its challenging as it’s the peak above 8000 meters. You will be walking on the long stretches of the snow and ice from where you will navigate gently through sloping glaciers, minor crevasses, and some steep sections near the summit ridge. Fixed ropes are often used in the final stretch.
The Cho Oyu peak is a summit focused climbing experience which teaches you how to build the endurance, makes you understand the mountains, and connects you with the Himalayan environment.
This high-altitude journey also tests your spirit, resilience, hard work, patience, and your mental and physical abilities.

Altitude Graph
Preparing properly for the Mount Cho Oyu expedition is essential for safety and comfort at high altitude. Since you’ll be climbing above 8,000 meters in cold, windy, and remote conditions, your gear should focus on warmth, layering, and reliable technical equipment. Below is a practical packing list to help you get expedition-ready.
Cho Oyu is located on the Nepal–Tibet border in the Mahalangur Himal range. With an elevation of 8,188 meters, it is the sixth-highest mountain in the world and one of the most popular 8,000-meter peaks due to its relatively less technical climbing route.
Cho Oyu is considered one of the least technical 8,000-meter mountains, making it ideal for climbers aiming to summit their first 8,000er. However, it is still an extremely demanding expedition that requires excellent physical fitness, strong mental endurance, and prior high-altitude climbing experience.
Participants should have prior experience climbing peaks above 6,000 meters, such as Ama Dablam, Island Peak, Lobuche Peak, or similar mountains. Familiarity with crampons, fixed ropes, ice axe use, and high-altitude camping is essential.
The best seasons for the Cho Oyu expedition are spring (April–May) and autumn (September–October). During these periods, weather conditions are relatively stable, visibility is good, and temperatures are more favorable for high-altitude climbing.
The complete Cho Oyu expedition typically takes 32 to 35 days, including arrival, acclimatization, rotations, summit push, and return. This duration allows proper acclimatization and increases safety and success rates.
While some elite climbers attempt Cho Oyu without oxygen, supplemental oxygen is strongly recommended for safety and comfort, especially during the summit push. Our expedition includes oxygen support as per the chosen package.
The summit is reached from Camp II during a long summit day.
Accommodation includes hotels in Kathmandu, lodges in Tibet (Kerung, Tingri, Thingri), and fully equipped expedition tents at Basecamp and high camps. High-altitude camps use shared climbing tents.
We provide full-board meals throughout the expedition, including freshly cooked meals at Basecamp and high camps. The menu includes Nepali, Tibetan, and international dishes designed to meet high-altitude nutritional needs.
Acclimatization is carefully planned through rest days, gradual ascents, and rotation climbs between Basecamp and higher camps. This systematic approach helps reduce the risk of altitude sickness and improves summit success.
Yes, comprehensive travel insurance covering high-altitude mountaineering and emergency evacuation is mandatory. Climbers must provide proof of insurance before the expedition begins.
All required permits, including Cho Oyu climbing permits, Chinese permits, and liaison officer fees, are included in the expedition cost. We handle all administrative and permit arrangements on your behalf.
Safety is our top priority. The expedition is led by experienced guides and Sherpas, with fixed ropes, medical kits, oxygen support, and continuous monitoring at Basecamp. Weather windows are carefully analyzed before any summit attempt.
Yes, the itinerary may change due to weather conditions, climber health, or safety concerns. Flexibility is essential in high-altitude expeditions, and decisions are always made in the best interest of the team.
Reaching the summit depends on weather, health, and individual performance. Even if you do not summit, the expedition still offers an extraordinary high-altitude climbing experience. No refunds are provided for unsuccessful summit attempts, as safety always comes first for summit 8000.
Climbing Cho Oyu is a serious 8,000-meter adventure, and understanding the real cost structure makes the whole journey a lot clearer. From the Tibet side, the total expense is split into two main parts: mandatory government permits and the full expedition package provided by your operator, in this case Summit 8000.
Most of the non-negotiable costs come from permits issued through Chinese authorities. The biggest one is the climbing royalty charged by the Chinese Mountaineering Association, which is roughly around $9,000–$9,500 per climber. On top of that, there’s an environmental or waste management fee of about $1,000 that goes toward keeping the mountain clean and regulated.
Every expedition also includes a government-appointed liaison officer who travels with the team. Their salary, travel, and accommodation are already bundled into the permit system and handled by the operator.
To enter and operate in the region, you’ll also need a Tibet Travel Permit along with a Chinese visa, both of which Summit 8000 arranges for you during your preparation period in Nepal. You’ll also get a Nepal entry visa on arrival at Kathmandu airport, which is typically around $125 for a 90-day multiple-entry option.
Once you successfully reach the summit, the Chinese Mountaineering Association issues an official summit certificate, which serves as international recognition of your climb.
The full guided expedition starts at around $25,000 per person. This isn’t just a permit fee it covers the entire logistics chain from Kathmandu to the summit and back.
It usually includes:
Once you move above base camp, everything is supported by a professional mountain team, including Sherpa guidance and oxygen management where needed.
There are a few expenses not included in the main package. The most important is high-altitude rescue and travel insurance, which must cover at least $90,000 and include helicopter evacuation from altitude. This is mandatory for all climbers.
You’ll also need to budget separately for your personal climbing gear, international flights to Kathmandu, and summit bonuses for Sherpa staff, which are standard practice in high-altitude expeditions.
When you compare it to other 8,000-meter peaks, Cho Oyu is still one of the most cost-effective major expeditions. For example, Everest permits alone can exceed $15,000, and total guided climbs often range anywhere from $50,000 to over $100,000.
Cho Oyu gives you the full high-altitude experience thin air, technical camps, and a full Sherpa-supported summit push but at a much more accessible overall cost. That’s why many climbers see it as a perfect entry point into the world of 8,000-meter mountaineering.
