Short answer: Cho Oyu (8,188 m) costs US$29,900–US$53,500 in published 2027 operator fees for a full-service expedition, and most climbers pay around US$37,500. Add US$6,800–US$27,000 for oxygen, staff bonuses, gear, flights, insurance and contingency, so a realistic all-in budget is US$36,700–US$80,500, typically US$52,300. Cho Oyu's Tibet permit is bundled by your operator through the Chinese mountaineering association, and access can close at short notice. Tibet access depends on Chinese permits, and some teams now use a Nepal-side route. ^[1][2]

Short answer, in my words

Cho Oyu has been the classic first 8,000er for decades: a wide, mostly non-technical route from Tibet with one short rock band and a long, flat summit plateau. The catch now is access. Chinese permits for Tibet have been unpredictable, so some operators run a newer, harder Nepal-side route, and prices reflect both options.

I've been climbing big mountains for 20 years and I've stood on the summit of Everest. The one thing I tell everyone who asks me about Cho Oyu is that the headline price is only the start. Below I've put every published operator price I could verify on the operators' own websites, a line-by-line budget with low, typical and high figures, and the costs that tend to surprise people.

Who is Cho Oyu right for?

First-time 8,000 m climbers with Aconcagua, Denali or a 7,000 m peak behind them, and Everest aspirants building altitude experience.

The full Cho Oyu cost breakdown

This is the budget I'd sketch out for a client. The operator fee is the big line and almost always includes the permit, base camp, the trek or drive in, and most group gear. Everything else is yours. Where I've used my own range, it's labelled “Blake estimate”. The extras add US$6,800 at the low end, US$14,800 typically and US$27,000 at the high end.

How I read those lines: the low column is a climber who already owns their kit, takes the package oxygen and flies on a sale fare. The high column is a first 8,000 m climber buying everything new, adding oxygen and a safety margin for an extra week of weather. Most people I advise land close to the typical column.

Every Cho Oyu operator with a published price

These are the prices each operator publishes on its own website, per climber, checked on 20 October 2026. I've sorted them from cheapest to most expensive. This is not a ranking and inclusions differ, so compare the Sherpa ratio, oxygen allowance and exclusions before you compare the number. Operators that only quote by email are left out because I can't verify what they charge.

The spread in that table is normal. The cheapest packages are usually run by Nepali or Pakistani companies with lower overheads, and the most expensive by Western-led teams with a foreign guide, more oxygen and smaller groups. In my experience the gap on the mountain is smaller than the gap in price, but it is real on summit day, when decisions are made. Before I shortlist a team I check its recent summit and accident record in the Himalayan Database ^[14] and in season reports from Alan Arnette ^[15].

What you get at each price level

Price on an 8,000 m peak buys four things: who makes decisions on the mountain, how much oxygen you breathe, how many Sherpas or high-altitude porters are with you, and how comfortable base camp is. Everything else is detail.

My rule of thumb: never cut oxygen or the Sherpa ratio to save money. Cut comfort instead.

What is climbing Cho Oyu really like?

For years I've recommended Cho Oyu as the best first 8,000er. From Tibet the route is relatively gentle, base camp is reachable by road, and the summit plateau is broad.

The catch is politics. China controls the Tibetan side and access for foreigners has been unreliable in recent seasons. Book with an operator that refunds or switches peaks if permits fall through.

The Nepal-side route, opened commercially only recently, is a harder, steeper climb. Don't book it thinking it's the same easy peak.

When is the Cho Oyu season and how long does it take?

Tibet: September to early October · Nepal side: spring and autumn. Plan on 30–45 days door to door from your arrival city, and build in a buffer week for weather.

Which route do expeditions use on Cho Oyu?

The commercial standard is the Northwest Ridge (Tibet); a newer, harder south-side route from Nepal. One of the least technical 8,000ers from Tibet; one short ice cliff above Camp 1.

What permits do you need for Cho Oyu?

Cho Oyu's Tibet permit is bundled by your operator through the Chinese mountaineering association, and access can close at short notice ^[1]. The newer Nepal-side route falls under Nepal's US$3,000 spring and US$1,500 autumn royalty for 8,000ers ^[16]. On almost every commercial package the operator buys the permit and includes it in the price, so check the inclusions list before you compare numbers. Liaison officer, garbage deposit and rope-fixing fees are usually inside the fee too, but not always.

Do you need bottled oxygen on Cho Oyu?

Often used from Camp 2 or Camp 3 (about 7,100–7,500 m); some climbers summit without it. Ask any operator for its flow rate and how many bottles per climber are stocked above high camp; it is the single most important safety question you can ask.

How safe is Cho Oyu? Success and death context

Cho Oyu from Tibet has one of the lowest death-to-summit ratios of the 8,000ers. Avalanche on the slopes below Camp 2 and the summit plateau in poor visibility are the main hazards. For ascent and death records by season, I use The Himalayan Database and Alan Arnette's season coverage.

Altitude, health and fitness

Before any 8,000 m expedition I'd see a doctor who understands altitude, and read the UIAA Medical Commission's advice ^[17] and the CDC's guidance on altitude illness ^[18]. On Cho Oyu the big risks are high-altitude cerebral and pulmonary oedema, frostbite and exhaustion on the descent. Training should build to long days carrying 15–20 kg, but altitude experience on 6,000–7,000 m peaks matters more than gym fitness. Check that your evacuation cover explicitly includes helicopter rescue at your altitude ^[5].

Where the money goes

Roughly, an operator's Cho Oyu fee pays for the permit, staff wages and insurance, the trek or drive to base camp, base camp food and tents, high-camp tents and stoves, fixed ropes and the rope-fixing team, oxygen and the cost of carrying it high, weather forecasts and communications, and the operator's margin. Western-led teams add guide salaries, flights for foreign staff and higher overheads, which is most of the price gap. Cho Oyu's Tibet permit is bundled by your operator through the Chinese mountaineering association, and access can close at short notice ^[1]. The newer Nepal-side route falls under Nepal's US$3,000 spring and US$1,500 autumn royalty for 8,000ers ^[16].

Hidden costs that catch people

These are the costs I see people forget most often when they budget for an 8,000 m peak.

• Permit changes. If China closes or changes access late, you may lose flights and part of the fee unless your contract says otherwise.
• Summit bonuses. Usually compulsory once the summit push starts; get the number in writing.
• Extra oxygen bottles. Charged per bottle.
• Visa and group permit days in Kathmandu or Lhasa. Hotels and meals while paperwork is processed.
• Very limited helicopter rescue. Evacuation from the Tibet side is slow, so insurance alone doesn't solve the problem.
• Lost income. Four to six weeks away from work.
• Nepal-side switch. If Tibet closes, the Nepal-side route is longer and more technical, and operators may charge the difference.

How to save money without cutting safety

• Choose a reputable local full-service team rather than the cheapest logistics-only permit.
• Buy 8,000 m boots and a down suit secondhand, or rent them in Kathmandu if you've tried them on first.
• Book international flights as soon as your dates are confirmed, with a changeable fare.
• Pay deposits by credit card and buy cancellation cover the day you pay.
• Never save money on oxygen, Sherpa ratio, insurance or the weather forecast.
• Ask whether a Tibet closure gives you a credit toward Manaslu the same season; some operators offer swaps.

Questions I would ask any operator before paying a deposit

1. Who is my expedition leader, and how many times have they summited this mountain?
2. What is the summit-day Sherpa or guide ratio, in writing?
3. How many oxygen bottles per climber are stocked above high camp, and at what flow rate?
4. What is the turnaround time and who enforces it?
5. Is the summit bonus compulsory, and how much is it?
6. Who pays if the permit is cancelled or the route closes?
7. What exactly is excluded from the price?
8. Which weather forecasting service do you use?
9. Do you carry a doctor or medic, and what is the evacuation plan?
10. Can I speak to two clients from last season?

Where prices are heading for 2027

Three things are pushing 8,000 m prices up: higher permit royalties (Nepal from September 2025 ^[16][19]), rising Sherpa wages and insurance, and helicopter and fuel costs. Competition between local operators keeps the budget end steady. For Cho Oyu I expect most 2027 prices to hold, with rises of 3–10% the following year.

My verdict

If you want a first 8,000er and can live with permit uncertainty, Cho Oyu is still a beautiful choice, and a full-service team at US$32,000–38,000 is good value. If you need certainty, I'd usually point you to Manaslu instead. Whatever you book, insist on written refund or swap terms if Tibet closes.
