Everest Base Camp Trek Guide 2026: Permits, Stages and What to Expect

The Everest Base Camp trek runs from Lukla to South Base Camp at 5,364 m and back. Foreign trekkers pay two entry fees: a Sagarmatha National Park permit (NPR 3,000) and, since July 2024, a Khumbu Pasang Lhamu Rural Municipality entry fee of NPR 3,000. Nepal's 2023 national rule requires foreign trekkers to hire a licensed guide, but the Khumbu Pasang Lhamu Rural Municipality has stated that a guide is not mandatory in the Everest region — check the current rule before you book.

Everest Base Camp Route: Stage-by-Stage Overview

The classic EBC route starts with a flight from Kathmandu to Tenzing-Hillary Airport in Lukla (2,860 m) — one of the world's most dramatic airstrips, with a runway 527 m long and an 11.7% gradient. From Lukla, the trail follows the Khumbu valley north-east through the Sherpa trading town of Namche Bazaar, the monastery at Tengboche and the village of Dingboche, before reaching Base Camp at the foot of the Khumbu Icefall. Build in acclimatisation days at Namche and Dingboche rather than rushing the ascent; they give your body time to adjust to the altitude.

Altitude and Acclimatisation: What You Must Know

Acute Mountain Sickness (AMS) is the main risk on the EBC route, especially for trekkers who ascend too fast. The "climb high, sleep low" principle is non-negotiable above 3,500 m: gain altitude during the day, return to a lower sleeping elevation each night. On the planned acclimatisation day in Namche, a day hike up to the Everest View Hotel and back is the standard protocol.

Symptoms of AMS include headache, nausea and fatigue disproportionate to exertion. Descend immediately if you experience confusion, loss of coordination or persistent vomiting — these indicate High Altitude Cerebral Edema (HACE), which is life-threatening and requires urgent descent. Diamox (acetazolamide) is a commonly used preventive medication — consult a doctor before departure.

Best Time to Trek to Everest Base Camp

October–November and March–May are the two optimal windows. The post-monsoon autumn window (October–November) brings the clearest skies and most stable weather, though nights at Gorak Shep are well below freezing. The pre-monsoon spring window (March–May) offers comparable conditions plus the unique spectacle of Himalayan expedition teams preparing summit bids on Everest itself. Avoid the monsoon (June–September): cloud cover obscures views for days at a time and leeches are common on the lower sections.

What to Pack for Everest Base Camp

Most EBC trekkers use a hired porter or yak to carry a duffel between tea houses, keeping a daypack on trail. Your sleep system is the single most critical gear decision — tea house blankets at altitude are often damp and inadequate. The Katabatic Gear Sawatch 15°F Quilt (700 g, rated to 15°F / -9°C) eliminates dependence on tea house bedding across the entire route. A comparable alternative is the Enlightened Equipment Revelation Quilt 20°F.

Trekking poles save your knees on the long descent back from Base Camp to Lukla. The Black Diamond Distance Carbon FLZ collapses small enough to strap to a daypack through Namche Bazaar where poles are unnecessary. A reliable headlamp is essential for early morning starts before Kala Patthar — the Nitecore NU25 UL (48 g) charges via USB-C and delivers 400 lumens, sufficient for pre-dawn scrambling above 5,000 m.

Before booking, read our 10-week altitude training guide and the Annapurna Circuit guide — Nepal's other classic multi-week trek — to compare the two routes.

Budget: What the EBC Trek Costs in 2026

The cost of a guided EBC trek depends on group size and agency quality. Tea house accommodation is a variable cost that tends to rise at higher elevations. Your budget should cover Kathmandu–Lukla flights, the two entry fees, food, tea houses and, if you hire one, a licensed guide. Get current quotes from several registered agencies before you book.

Frequently Asked Questions

Do you need to be fit to trek to Everest Base Camp?

Moderate fitness is sufficient for most healthy adults. You should be comfortable hiking 6–8 hours per day across multiple consecutive days before departing. The main challenge is altitude exposure, not technical terrain — the trail is well-maintained and non-technical. Sustained aerobic training (hiking, cycling or running) for 8–12 weeks beforehand significantly reduces altitude sickness risk.

How cold is it at Everest Base Camp at night?

Temperatures at EBC (5,364 m) drop to -10°C to -20°C overnight, even in the peak months of October and April. At Gorak Shep (5,164 m), tea house dormitories hover around -5°C inside. Bring a sleeping bag or quilt rated to at least -10°C and a warm insulation layer for evenings in the tea houses.

Can you get altitude sickness on the EBC trek?

Yes. AMS affects the majority of trekkers above 3,500 m. Symptoms include headache, nausea and fatigue. Follow a gradual acclimatisation schedule, stay well hydrated and descend immediately if symptoms worsen overnight. Never ascend if you still feel symptoms from the previous day's gain.

Is a guide compulsory for the EBC trek in 2026?

Yes. Nepal's government banned solo trekking in the Khumbu region. All foreign trekkers must hire a licensed guide, arranged through a registered Kathmandu or Lukla trekking agency. The rule applies to the full EBC route within Sagarmatha National Park.

What is the best month to trek to Everest Base Camp?

October and November offer the clearest skies and most stable weather. April and May are equally popular with the added spectacle of Himalayan expedition teams at Base Camp. Avoid June through September when monsoon cloud obscures views and rain makes lower-elevation sections muddy and leech-infested.
