Everest Base Camp Trek: The Complete Guide to EBC

The Everest Base Camp (EBC) trek is not just a hike — it is the most iconic trek on the planet. Standing at 5,364 metres, at the foot of the highest peak on Earth, surrounded by glaciers and prayer flags, is a once-in-a-lifetime experience. This is the complete, practical guide for travellers from Greece: how many days, how much it costs in euros, which permits you need, how acclimatization works and what really awaits you on the trail to Everest Base Camp.

The essentials at a glance

Before the details, here is the profile of the route:

Getting there: from Athens to Lukla

There is no direct flight from Greece. You fly Athens → Kathmandu with one stop (Turkish via Istanbul, Qatar via Doha, or Emirates/Etihad via Dubai/Abu Dhabi). Travel time is around 12–18 hours and a round-trip ticket typically costs €430–800. More in our general guide to trekking in Nepal.

From Kathmandu, the classic EBC begins with one of the most spectacular flights in the world: the small aircraft lands at Lukla's Tenzing–Hillary Airport (2,860m), famous for its short, steeply sloped runway clinging to the mountainside. The flight takes just 30–40 minutes and costs roughly €350–420 round trip. Note: during peak season (spring/autumn) flights are often moved to Ramechhap (Manthali) airport, a 4–5 hour drive from Kathmandu, due to congestion. Weather delays or cancels flights regularly — always keep 1–2 buffer days in your plan.

The day-by-day itinerary

The classic 12-day hiking route — with two crucial acclimatization days — is the safest and most popular:

Many agencies add an extra acclimatization day or a buffer for flight delays, reaching 13–14 days. Don't rush: every day you save on the schedule, you lose in protection against altitude sickness.

Namche Bazaar & the teahouses

Namche Bazaar (3,440m) is the "capital" of the Sherpa and the trading hub of the Khumbu: built like an amphitheatre, with cafés, bakeries, gear shops and even ATMs (don't rely on them — carry cash). Here you spend your first big acclimatization day.

Along the whole route you overnight in teahouses — simple family-run lodges with basic twin rooms, shared toilets and a warm dining room heated by a stove. The food is simple but filling: dal bhat (rice with lentils, with free refills) is the trekker's fuel. As you climb, prices rise — a plate might cost €3 in Lukla and €8 in Gorak Shep, since everything comes up by yak or porter. Hot showers, WiFi and device charging are usually extra.

How hard is it really?

EBC does not require technical climbing, crampons or ropes — it is hiking on well-trodden trails. Its difficulty lies in three things: (1) the duration — 5 to 8 hours of walking every day for nearly two weeks; (2) the altitude — the thin air above 4,000m makes every step harder; (3) the ups and downs — the Khumbu valley is a constant switch between climbs and descents. With 2–3 months of preparation (cardio, weighted hikes, stairs) a healthy person with no mountain experience can manage it comfortably. Fitness helps, but patience with acclimatization matters more than speed.

Altitude & acclimatization — the number one risk

Above 2,500m the body starts reacting to the thin air. Altitude sickness (AMS) is the real danger on EBC — not cliffs. The golden rules:

• "Climb high, sleep low": gain altitude during the day, but sleep lower.
• Above 3,000m, don't raise your sleeping altitude by more than 300–500m per day.
• Respect the acclimatization days (Namche, Dingboche) — they are not optional.
• Drink 3–4 litres of water, avoid alcohol, and never ignore headache, nausea or insomnia.
• Diamox (acetazolamide) 125mg × 2 helps with prevention — discuss it with your doctor before the trip.
• The golden safety rule: if symptoms worsen, descend. Descent is the only sure cure.

Read in detail what it is, how to prevent it and when to descend in our dedicated guide to altitude sickness in the Himalayas. And don't forget: your travel insurance must cover trekking above 5,000m and helicopter evacuation — in the Khumbu, heli rescue is the standard for a serious incident.

Permits

For EBC you need two permits (the old TIMS card is no longer required in the Everest region):

Around €40 total. If you book an organized trek, the agency handles them for you. See every permit category (TIMS, ACAP, Sagarmatha, restricted areas) in our guide to Nepal trekking permits.

Do you need a guide?

Essentially yes. Since 2023 Nepal does not allow independent trekking without a licensed guide in national parks and many trekking areas. Beyond the rule, an experienced Sherpa guide offers altitude safety, weather knowledge, lodging logistics and priceless cultural connection. A porter is optional but transforms the experience, carrying 10–15 kg so you walk with only a light daypack. A tip at the end is customary: around $80–100 for the guide and $20–40 for the porter.

Cost in euros

EBC can be done on very different budgets. An indicative breakdown excluding the international airfare:

Add €430–800 for the Athens–Kathmandu ticket, plus a margin for insurance, gear and days in Kathmandu. An organized package costs more but includes permits, flights, guide, lodging and emergency support — for a trek at this altitude, it is worth it.

Best time for EBC

Autumn gives the most stable weather and the most brilliant view of the peak. See a full breakdown of the best time to visit Nepal by activity.

What to pack

The key is the layering system: thermal base layer, fleece, a waterproof/windproof shell and a thick down jacket for the freezing mornings. Essentials: good hiking boots (broken in beforehand), a −15°C sleeping bag, high-protection sunglasses, sunscreen, trekking poles, a first-aid kit with Diamox and water purification tablets. Much of the gear can be rented or bought cheaply in Kathmandu's Thamel. Full checklist in our guide on what to pack for Nepal.

Useful practical tips for the trail

• Connectivity: the NTC SIM has better mountain coverage than Ncell — there is 4G even above Namche. Alternatively, get an eSIM (Airalo) before arrival.
• Cash: carry enough rupees from Kathmandu. ATMs in Lukla and Namche often don't work or charge high fees, and above Namche there are none at all.
• Water: don't drink tap water. Use purification tablets or a filter; bottled water gets very expensive as you climb and adds plastic waste.
• Side-trips: with extra days, the Gokyo lakes and the Cho La pass are worth it, or a stop at Tengboche monastery for the monks' evening ceremony.
• Pace: walk slowly and steadily — "bistari, bistari" as the Sherpa say. At altitude, a slow pace is not weakness; it's strategy.

EBC or ABC — which should you choose?

Nepal's two top treks suit different profiles:

If it's your first big trek or you're short on time, start with Annapurna Base Camp. If you're after the ultimate experience and have 16–18 days, Everest Base Camp is the final destination.

Plan your EBC — with premium support

Everest Base Camp is a trek you don't leave to chance. Good organization — permits, Lukla flights, an experienced Sherpa guide, a realistic acclimatization schedule and insurance with heli evacuation — is the difference between a lifelong dream and a bad experience.

Whether you choose to go independently or organized, the base camp of Everest is waiting.
