Published · Researched 2026-09-21
Research date: 2026-09-20. Permit fee verified against multiple 2025–2026 sources (dated below). Expedition costs and logistics change yearly — re-verify with your outfitter and Nepal's Department of Tourism before committing.
Overview
| Field |
Detail |
| Difficulty |
Extreme — high-altitude expedition; technically moderate on the South Col route (fixed lines, ladders in the Khumbu Icefall) but physiologically brutal |
| Best season |
Pre-monsoon: April–May (the classic window). Post-monsoon (Sept–Oct) possible, colder and windier |
| Duration |
8–9 weeks total (~60–65 days) |
| Permits/fees |
Nepal climbing permit for Everest (South Col/normal route): $15,000/person spring (Mar–May), $7,500 autumn, $3,750 winter/monsoon — raised from $11,000/$5,500/$2,750 effective 1 September 2025 per Nepal's Mountaineering (Sixth Amendment) Regulations 2081 (sources: wildernessexcursion.com, Aug 2026; mysticadventureholidays.com, Aug 2026; advnture.com, Jan 2025 announcement). Other Everest routes: $10,000 spring. Nepali nationals pay NPR 150,000 spring (doubled from 75,000). Sagarmatha National Park entry + Khumbu local fees are separate and smaller |
Typical 8–9 Week Phase Plan (spring)
| Phase |
Approx. timing |
What happens |
| 1. Kathmandu |
Days 1–5 |
Arrive, outfitter briefing, permit/visa formalities, gear check, last supplies (Thamel gear shops), team puja |
| 2. Lukla → Base Camp trek |
Days 6–14 |
Fly to Lukla (weather-dependent), trek via Namche Bazaar → Tengboche → Dingboche → Lobuche → Gorak Shep → Everest Base Camp (5,364 m). Deliberately slow for acclimatization |
| 3. BC establishment + Khumbu Icefall training |
Days 15–22 |
Settle into BC, practice ladder crossings and fixed-line travel in the lower Icefall, rest |
| 4. Rotations |
Days 23–45 |
Rotation 1: BC → Camp 1 (6,065 m) → Camp 2 (6,400 m), back to BC. Rotation 2: → Camp 3 (7,200 m, Lhotse Face), back to BC. Some teams touch Camp 4 (7,950 m, South Col). Descend to a lower village (Pheriche/Deboche) between rotations to recover |
| 5. Summit push |
Days 46–55 |
Weather window: BC → C1 → C2 → C3 → C4 → summit (8,849 m) via the Balcony, South Summit, Hillary Step → descend to C4/C2. Summit day from the South Col is typically 10–14+ hours round trip |
| 6. Trek out |
Days 56–65 |
Descend to BC, trek to Lukla, fly to Kathmandu, debrief, celebration, fly home |
Oxygen Logistics
- Nearly all guided South Col climbers use supplemental oxygen above Camp 3 (many from Camp 2). Typical usage is on the order of 5–8 bottles per climber for the expedition — exact counts vary by outfitter and flow-rate strategy; treat as UNVERIFIED for any specific operator and confirm in writing.
- Outfitters supply oxygen, regulators, and masks on full-service packages; budget operators may charge per extra bottle.
- Climbing Sherpa oxygen use is built into reputable operators' plans (your Sherpa climbs with you on O2).
- Know the failure drill: regulator freeze, mask icing, bottle swap at the Balcony — practice at lower camps.
- Oxygen is logistics, not a substitute for acclimatization. The rotations above are what keep you alive.
Sherpa Support Model
- Standard commercial ratio is ~1 climbing Sherpa per client on full-service expeditions (budget operators may be 1:2 or shared).
- Sherpas fix lines, carry group oxygen and camp loads, set high camps, and climb with clients on summit day. On reputable teams the Sherpa team also leads Icefall route maintenance through the SPCC (Sagarmatha Pollution Control Committee) rope-fixing collaboration.
- Summit bonuses and tips are customary and significant — budget several thousand dollars (see budget notes).
- High-altitude workers' insurance and rescue coverage should be in your outfitter's contract — ask to see it.
Outfitter-Provided vs Personal Gear (explicit split)
Typically provided (confirm in contract): climbing permit, Sagarmatha NP fees logistics, all high-camp tents, fixed ropes and Icefall ladders (via team fees), group food (BC + high camps) and cooking, oxygen + regulators, climbing Sherpa(s), Base Camp infrastructure (dining tent, comms, medical tent), weather forecasting, evacuation coordination, Lukla flights and porters/yaks on the trek.
Personal (checklist below): all clothing, boots, sleeping system, harness/crampons/axe, pack, duffel, personal electronics, meds, and usually your own oxygen mask (confirm).

Key Risks
- Altitude illness (AMS/HAPE/HACE) — the great decider. The rotation schedule exists to prevent it; skipping acclimatization to chase a window kills people.
- Khumbu Icefall — moving seracs and crevasses between BC and Camp 1; cross early, cross fast, minimize transits.
- Weather windows and crowding — narrow summit windows concentrate hundreds of climbers; 2026 saw a record 492 foreign permits (Nepal DoT, May 2026). Bottlenecks at the Hillary Step in the death zone are a real hazard.
- The death zone (above ~8,000 m) — the body deteriorates; speed and turnaround discipline matter more than strength.
- Frostbite — hands, feet, face. Oxygen-system failures compound it.
- Evacuation limits — helicopters can't always fly; above Camp 2 rescue is often carried out by your own team or not at all.
Honest Budget Notes (dated sources, 2026-09-20)
- Permit alone: $15,000 spring (since Sept 2025) — this is just the royalty; the expedition costs much more.
- Guided expedition average: ~$60,000 per foreign climber for a professionally organized expedition in 2026, per Rajendra Lama, Secretary-General of the Nepal Mountaineering Association (via politicallore.com, Sept 2026), with a typical range of $45,000–70,000+; premium/private expeditions run far higher ($90,000–180,000+ for VIP/luxury tiers per industry breakdowns).
- Budget operators advertise ~$33,000–45,000 but with thinner Sherpa ratios, fewer O2 bottles, and less margin — understand exactly what "budget" removes.
- Not in the headline price: international flights, personal gear ($5,000–15,000 if buying new), high-altitude evacuation insurance ($2,000–4,000+), Sherpa summit bonuses and tips (several thousand), Kathmandu hotels/meals, and contingency cash.
- Re-verify the permit fee with Nepal's Department of Tourism and your outfitter's contract before paying anything. Fees changed in Sept 2025 after nearly a decade — they can change again.
