South Col vs North Ridge
The world’s highest peak offers two viable routes to the same summit — from opposite sides of the mountain, through different countries, with different technical demands, different permit systems, and different Death Zone hazards. Here is every variable that separates them.
South Col, North Ridge & Technical Routes at a Glance
Everest has two viable standard routes and a spectrum of technical lines that see very limited attempts annually. The South Col (Nepal) accounts for the majority of modern attempts due to its superior Sherpa infrastructure and more developed commercial guiding ecosystem. The North Ridge (Tibet) offers a different technical profile, avoids the Khumbu Icefall, but faces its own serious challenges on the Second and Third Steps above 8,500m.

South Col Route (Nepal)
Primary Commercial RouteThe South Col Route is the most climbed high-altitude route in the world and the line on which Tenzing and Hillary made the first ascent in 1953. It approaches through the Khumbu Valley, passes through the Khumbu Icefall (the route’s primary objective hazard), ascends the Western Cwm to the Lhotse Face, and reaches the South Col before the final push through the Balcony, South Summit, Hillary Step, and true summit. The route’s 32% overall success rate rises to 38%+ for well-supported commercial teams in good seasons — the highest achievable rate on either standard Everest route.
Overview & Character
The South Col Route is Everest’s commercial infrastructure at full scale. The Icefall Doctors — a team of Sherpa specialists — establish and maintain the Khumbu Icefall ladder and rope system each season. High-altitude Sherpa teams fix ropes from Camp 2 to the summit. Weather forecasting services provide 5–7 day window predictions. The entire apparatus is oriented toward maximising the summit probability of commercial clients using supplemental oxygen on the standard line. No other route on any mountain in this database has equivalent support infrastructure.
The South Col’s primary structural challenge has shifted in the modern era from technical difficulty to Death Zone crowding. The bottleneck at the South Summit and Hillary Step in the narrow May weather window now regularly traps climbers in stationary queues above 8,750m — conditions that are directly life-threatening regardless of fitness or oxygen reserves. Teams that are positioned and ready when the window opens, and that move efficiently through the Death Zone, consistently outperform those caught in queues.

Route-Specific Gear Notes
The South Col route requires a complete 8,000m gear system: a down suit rated to -50°C, double-layer mountaineering boots, supplemental oxygen with mask and regulator, 12-point crampons, ice axe, harness, and a layering system for the Death Zone. Operators typically provide oxygen cylinders, tents, and fixed rope access fees. Personal gear costs for the South Col average $8,000–$15,000 before operator fees. See the complete Everest gear list for a full breakdown.
North Ridge Route (Tibet)
The Alternative SideThe North Ridge approaches from the Tibetan side via the Rongbuk Glacier, reaching Chinese Base Camp (5,150m) by road from Lhasa or Kathmandu via Friendship Highway. The route ascends to the North Col (7,010m), continues along the Northeast Ridge to the three steps above 8,500m, and reaches the summit from the north. It avoids the Khumbu Icefall entirely — the South Col’s most significant objective hazard — but presents its own serious technical challenge in the Second and Third Steps at extreme altitude.
Overview & Character
The North Ridge is a different mountain than the South Col route in almost every experiential dimension. Road access to the Tibetan plateau means teams arrive at Chinese Base Camp (5,150m) by vehicle — dramatically faster than the Khumbu trek — but at a lower altitude requiring extensive acclimatization before the technical climbing begins. The route’s atmosphere is more remote, less commercially managed, and requires stronger independent expedition capability despite using supplemental oxygen and Sherpa support.
The Second Step at approximately 8,610m is the North Ridge’s defining technical section — a 40m near-vertical rock band at extreme altitude that was first climbed by Conrad Anker free in 1999 (previously ascended using a Chinese ladder installed in 1975). The ladder remains and most teams use it, but the approach and departure from the ladder section require confident movement on extremely exposed terrain while severely hypoxic. This section has no equivalent on the South Col route and is the primary reason the North Ridge requires stronger technical credentials than the South Col for comparable teams.

Technical Routes (Brief)
Everest’s technical lines — including the Northeast Ridge, West Ridge Direct, South Pillar, and various oxygen-free ascents — are beyond the scope of commercially-oriented route comparison. They share the same summit and the same Death Zone demands as the standard routes, compounded by sustained technical difficulty at altitudes where most humans cannot survive. Their 5–15% success rates reflect the most demanding mountaineering undertaken anywhere on Earth.
Who Should Choose Each Route
- Maximising summit probability is the primary goal
- You want the most developed commercial infrastructure and operator choice
- Prior Himalayan expedition experience is in Nepal — the Sherpa ecosystem is familiar
- Technical rock climbing at extreme altitude is not a specific strength
- You are comfortable accepting the Khumbu Icefall’s objective hazard in exchange for superior support
- Your operator has a demonstrable turnaround protocol and oxygen management system
- Technical rock climbing competence at extreme altitude is established — the Second Step is non-negotiable
- Avoiding the Khumbu Icefall’s objective hazard is a specific priority
- Prior Tibet expedition experience and CTMA logistics familiarity are in place
- The historical significance of the North Ridge is a specific motivation
- Regulatory risk from CTMA permit changes is acceptable and insured against
- A Tibetan plateau base camp environment is preferred over the Khumbu trekking infrastructure
Weather Windows Compared by Route
Both routes share the same May pre-monsoon summit window, driven by the same jet stream mechanics. The differences are in how each route’s exposure interacts with the window — and how quickly teams can act when conditions open. See the full best time to climb Everest guide for detailed seasonal analysis.
The North Ridge’s window typically opens slightly later than the South Col’s, reflecting the Tibet side’s greater wind exposure before the pre-monsoon jet stream lifts fully. Both routes are entirely weather-dependent at the summit level — the most important Everest planning decision is not route but patience. Teams that are positioned at high camp and willing to wait for a confirmed 3-day window consistently outperform those that push in marginal conditions or are committed to fixed departure dates.
Permit & Fee Differences
Everest permit costs are the highest of any mountain in this database and differ meaningfully between the Nepal and Tibet sides. See the full Everest permits and fees guide and complete cost breakdown for current figures.
| Fee category | South Col (Nepal) | North Ridge (Tibet) |
|---|---|---|
| Climbing permit | $11,000/person (NMA 2025)fixed quota | ~$9,000/person (CTMA 2025) |
| Liaison officer (mandatory) | ~$3,000–$5,000 | ~$2,000–$4,000 |
| Icefall Doctors fee | ~$3,000/team (shared) | Not applicableno icefall |
| Base camp infrastructure | $8,000–$15,000 (operator) | $6,000–$12,000 (operator) |
| Sherpa / high-altitude staff | $6,000–$15,000/Sherpa | $5,000–$12,000/Sherpa |
| Oxygen cylinders (10 bottles) | $5,000–$8,000 | $5,000–$8,000 |
| Full guided program (total) | $50,000–$130,000most operator choice | $40,000–$90,000 |
| CTMA permit risk | None | Cancellation risk — insure separately |
The North Ridge’s lower headline permit cost is partially offset by the regulatory risk: CTMA permit cancellations have stranded expeditions with limited refund options in multiple seasons. Any North Ridge budget must include expedition insurance that specifically covers permit revocation — a policy feature that standard travel insurance rarely includes.
Operator Availability Per Route
- 40+ licensed operators offer South Col programs; 8–10 have consistently strong track records
- Guided success rate: ~38% vs independent ~8% — the largest gap in this database
- Operator selection is the single most impactful planning decision on Everest
- Key question: what is your turnaround protocol at the South Summit? What is your oxygen contingency if a regulator fails?
- Budget operators exist — success rates and safety records differ substantially from premium operators
- Typical full-service guided cost: $50,000–$130,000 all-in
- 10–15 operators offer North Ridge programs; Tibet-specialist experience is essential
- CTMA logistics require operators with established Chinese government relationships
- Second and Third Step guidance requires operators who have specific technical experience on this section
- Fewer budget options — the smaller permit pool limits competitive pricing
- Verify CTMA permit insurance and cancellation policy before any deposit
- Typical full-service guided cost: $40,000–$90,000 all-in
Our Recommendation by Climber Profile
Everest’s route verdict is the most nuanced in this database — because both standard routes are appropriate for experienced climbers, and the choice between them is driven by specific technical strengths, operator relationships, and risk tolerance rather than a simple better/worse assessment.
On Everest, operator selection outweighs route selection as a success predictor. The difference between a top-tier South Col operator (38%+ success rate) and a budget South Col operator (18–22% success rate) is larger than the difference between the South Col and North Ridge. Research your operator’s turnaround protocol, oxygen management system, and Sherpa-to-client ratio before any other planning decision.
