The trek to Everest Base Camp is the most famous walk in the Himalaya, and it earns it. Over 12 to 14 days you climb from the airstrip at Lukla through Sherpa villages, across swaying suspension bridges hung with prayer flags, past the great monasteries of Tengboche, to the foot of the Khumbu Icefall at 5,364 metres — with the classic sunrise viewpoint of Kala Patthar (5,644 m) as the true high point. No technical climbing is involved; the challenge is altitude, and the infrastructure of teahouses makes it the most accessible great high-altitude trek in the world.
The route is about 130 kilometres round trip, and the rhythm that makes it work is slow: short walking days, two acclimatisation stops, and the discipline to turn your pace down when your body asks. Most people who struggle on this trek struggle because they rushed, not because they were unfit.
The route
The classic 14-day shape: fly to Lukla, trek to Phakding and Namche Bazaar (3,440 m), spend two nights in Namche with an acclimatisation hike to the Everest View Hotel, then Tengboche (3,860 m), Dingboche (4,410 m) with a second acclimatisation day, Lobuche (4,940 m), Gorak Shep, and the walk to Base Camp itself. Next morning climb Kala Patthar for sunrise over Everest, then descend — usually in three to four days back to Lukla, often via Pheriche. Faster 12-day itineraries exist but leave less margin for altitude; if you have the days, take the slower version.
Lukla flights
The 30-minute flight from Kathmandu to Lukla is the trek’s famous bottleneck. One-way fares are currently in the region of US$215-255, so budget roughly US$430-510 for the return. In peak season flights often operate from Ramechhap instead of Kathmandu — a 4 to 5-hour drive before dawn — and weather delays of a day or more are normal. Build at least one or two buffer days into your itinerary, and don’t schedule an international flight home the day after you plan to fly out of Lukla.
Permits
You need two: the Sagarmatha National Park entry permit (NPR 3,000, about US$25) and the Khumbu Pasang Lhamu Rural Municipality permit (around NPR 2,000-3,000, roughly US$18-25). The old TIMS card is no longer required for the Everest region — the municipality permit replaced it. On guides: the Khumbu has been treated as an exception to Nepal’s 2023 rule requiring licensed guides on treks, with many independent trekkers walking unguided — but operators’ advice conflicts on whether this is being tightened, so verify the current requirement at a permit office or with a Kathmandu agency before you fly to Lukla.
Costs and budgeting
Independent trekkers who carry their own pack and eat local food typically spend US$950-1,300 for the in-Nepal portion: flights, permits, teahouses (US$5-10 per night, cheaper if you eat your meals there), and food at roughly US$25-40 per day. Expect prices to climb with altitude — a dal bhat that costs around US$4 in Lukla can be US$8 at Gorak Shep. Standard guided group packages run US$1,500-2,500 including guide, porter, flights and permits; private and luxury treks go higher. A licensed guide costs roughly US$25-35 per day and a porter US$18-25 per day if hired locally. Extras add up: hot showers, device charging and wifi all cost a few dollars a time at higher villages. Travel insurance with helicopter evacuation cover (US$80-150) is essential — an evacuation from altitude without it costs US$3,000-5,000.
Altitude and acclimatisation
This is the heart of the trek. Above 3,500 metres, follow the standard rules: climb high, sleep low on acclimatisation days; never ascend with symptoms of altitude sickness; and know that the cure for worsening symptoms is descent, not determination. Namche and Dingboche rest days are built into every sensible itinerary — don’t skip them to “save time”. The teahouses sell garlic soup as folk prevention; the evidence-based measures are pacing, hydration and rest days.
When to go
Two seasons: pre-monsoon (March to May), when rhododendrons bloom and Base Camp itself is busy with expeditions, and post-monsoon (late September to November), with the clearest mountain views. December to February is possible but bitterly cold at altitude; the summer monsoon brings cloud and leeches on the lower trail.
Practical tips
Gear rental in Kathmandu’s Thamel district costs roughly US$50-100 for the trek and is good quality — many trekkers rent down jackets and sleeping bags rather than buying. Pack a headlamp, water purification, and layers for -15°C nights at Gorak Shep. Carry cash in rupees; there are ATMs in Lukla and Namche but they are unreliable. And start your walking days early: the classic pattern is clear mornings with cloud building by afternoon.
