Everest Base Camp Trekking: What to Know Before You Go

Everest Base Camp trekking is a 12–14 day teahouse trek from Lukla to 5,364 m and back, best done in spring (March–May) or autumn (October–November) with at least two acclimatization nights built in. You need a Sagarmatha National Park permit and a Khumbu Pasang Lhamu Rural Municipality permit, a flight or helicopter transfer to Lukla, and enough fitness to walk 5–7 hours a day for two weeks. This guide covers the decisions that most affect whether you finish comfortably: season, itinerary length, permits, altitude strategy, fitness, and cost.

Season: when the trek actually works

If your priority is views, choose autumn. If you want fewer people and can handle cold, late November or early December is a reasonable middle ground.

Itinerary length and acclimatization

A 12-day Lukla-to-Lukla itinerary is the practical minimum; 14 days is safer. The difference is acclimatization, not distance.

A standard 14-day shape:

• Day 1: Fly Kathmandu–Lukla (2,840 m), trek to Phakding (2,610 m)
• Day 2: Phakding to Namche Bazaar (3,440 m)
• Day 3: Acclimatization day in Namche — hike to Everest View Hotel (3,880 m)
• Day 4: Namche to Tengboche (3,860 m)
• Day 5: Tengboche to Dingboche (4,410 m)
• Day 6: Acclimatization day in Dingboche — hike to Nangkartshang (5,083 m)
• Day 7: Dingboche to Lobuche (4,940 m)
• Day 8: Lobuche to Gorak Shep (5,164 m), then Everest Base Camp (5,364 m) and back
• Day 9: Gorak Shep to Kala Patthar (5,545 m) for sunrise, then down to Pheriche (4,371 m)
• Day 10: Pheriche to Namche
• Day 11: Namche to Lukla
• Day 12: Fly Lukla to Kathmandu

Two buffer days cover weather delays at Lukla. Skipping the Namche or Dingboche rest days is the single most common reason trekkers turn around early.

Permits and getting to Lukla

Two permits are required:

• Sagarmatha National Park entry permit — checked at Monjo
• Khumbu Pasang Lhamu Rural Municipality permit — for the Lukla–Namche section

Both are normally arranged in Kathmandu or by your trekking agency before departure. Carry passport copies and passport photos.

Lukla flights depart from Kathmandu (and seasonally from Ramechhap, which adds a 4–5 hour drive). Flights are weather-dependent and cancel often. Alternatives:

• Helicopter transfer — faster and more reliable, significantly more expensive
• Shared helicopter — a middle option when flights are grounded
• Trek in from Jiri or Salleri — adds 5–7 days, avoids the flight entirely

Build at least one spare day at the end of your trip for the return flight.

Fitness and altitude

You do not need technical climbing skills, but you do need aerobic base and the ability to walk uphill for hours with a light pack.

Training that helps:

• 8–12 weeks of hiking with a 5–8 kg pack, ideally on hills
• Stair or incline treadmill sessions, 45–60 minutes
• Long weekend walks of 4–6 hours to test boots and stamina

Altitude is the real variable. Acute mountain sickness (AMS) affects a large share of trekkers above 3,000 m regardless of fitness. Practical rules:

• Ascend no more than 300–500 m per day above 3,000 m once acclimatized
• Sleep no more than 500 m higher than the previous night
• Take the rest days
• Descend immediately if symptoms worsen — headache that won't shift, vomiting, breathlessness at rest, confusion

Carry acetazolamide if your doctor approves it, and know that descent is the only reliable treatment. Travel insurance covering helicopter evacuation above 5,000 m is essential; check the altitude limit on your policy.

Costs and what's typically included

Trek costs vary widely by group size, service level, and whether you go private or join a small group. A local operator typically bundles:

• Airport transfers and Kathmandu hotel nights
• Kathmandu–Lukla–Kathmandu flights
• All permits
• Licensed guide and porter(s)
• Teahouse accommodation and three meals a day on the trail
• Staff insurance, wages, and equipment

Usually not included: international flights, Nepal visa, travel insurance, personal gear, hot showers, Wi-Fi, battery charging, drinks, tips, and helicopter evacuation if needed.

Budget separately for the trail extras — they add up over 12 days. For current pricing, request a quote through the operator's Plan Your Trip page rather than relying on older published figures.

Common problems and how to handle them

Lukla flight cancelled. Wait it out if you have buffer days; otherwise ask about a shared helicopter. Do not book a tight international connection home.

AMS on the way up. Rest, hydrate, and if symptoms don't improve within a day, descend. Pushing to Gorak Shep with a bad headache is how evacuations happen.

Teahouses full in peak season. Trek with an agency that books ahead, or start walking early and stop by mid-afternoon.

Packing mistakes. The most common are too much weight and inadequate layering. You need a down jacket, a -10 °C to -15 °C sleeping bag (or a rented one), broken-in waterproof boots, and a 30–40 L daypack. Porters carry roughly 15–20 kg, so keep your duffel under that.

Cash. Bring more Nepali rupees than you think you need — there are no ATMs above Namche, and card payment is rare on the trail.

Choosing an operator

Since 1998 operators with a Kathmandu base and a guide-to-trekker ratio you can verify are the safest bet. Ask specifically about:

• Guide altitude experience and first-aid certification
• Porter insurance and load limits
• Group size (small group or private)
• What happens if you need to descend early
• Whether the itinerary includes both acclimatization days

A company that answers these directly and adjusts the itinerary to your dates is more useful than one that only quotes a price.
