The Everest Base Camp trek is a 12 to 14-day walk of roughly 80 miles (130 km) round trip, topping out at 17,598 feet (5,364 m). You do not need climbing skills, ropes, or any previous experience at altitude to do it. What you do need is patience with thin air, tolerance for cold nights, and a willingness to walk far more slowly than feels natural.
Paige asked me to write down the things I wish every trekker knew before they landed in Kathmandu. I have walked this trail with people in their twenties who struggled badly and people in their sixties who cruised, and the difference is almost never fitness. It is preparation, pacing, and knowing what you actually signed up for.
Key Takeaways
- Distance: around 80 miles / 130 km round trip from Lukla
- Duration: 12 to 14 days on trail, plus buffer days for flights
- Highest point: Kala Patthar, 18,192 ft (5,545 m). Base Camp itself sits at 17,598 ft (5,364 m)
- Permits: two, about NPR 6,000 (roughly US$40) total. No TIMS card needed in the Khumbu
- Best months: March to May, and late September to November
- Biggest risk: altitude, not terrain
- Budget: roughly US$1,400 to US$2,500 for a guided package, plus international flights
Quick Info About the Everest Base Camp Trek
- Trail Difficulty: Moderate, with one enormous asterisk. There is no technical climbing, no scrambling, and no exposure that would frighten a confident day hiker. The asterisk is oxygen. At Base Camp you breathe roughly half the oxygen you get at sea level, and that turns an easy hill into a hard one.
- Typical Day: 4 to 7 hours of walking, 1,000 to 2,000 ft of gain. Shorter than most people expect. That is deliberate.
- Beware of: Going too fast on days two and three. Nearly every case of altitude sickness I have dealt with started with someone feeling great early and pushing.
- Water Availability: Teahouses sell boiled water at every stop. Bring a filter or purification tablets and refill rather than buying bottled water, which gets expensive the higher up and creates plastic that the region has no way to remove.
- Toilets and Showers: Squat toilets are normal above Namche. Hot showers exist, but above Dingboche, they are a bucket and a boiler, and they cost extra.
How Hard is the Trek to Everest Base Camp, Really?
Physically, the trek to Everest Base Camp is easier than most people fear and harder than the photographs suggest. If you can comfortably hike 10 to 12 miles on hilly ground, several days in a row, you already have the legs for it. No section requires a rope or a helmet.
What breaks people is accumulation. You are walking every day for two weeks, sleeping badly, eating repetitive food, and doing all of it with less oxygen each morning. Day nine is harder than day two, even though the distance is shorter.
The best preparation I have seen is not gym cardio. It is back-to-back weekend hikes with a loaded pack, done for two or three months before you fly. Get your feet, your hips, and your patience ready, in that order.
What Does Altitude Sickness Actually Feel Like?
Mild altitude sickness feels like a hangover you did not earn. Dull headache, no appetite, broken sleep, mild nausea. It is common above 11,000 ft and usually settles if you rest and stop climbing for a day.
The signs that matter are different. Confusion, loss of balance, a wet cough, or breathlessness while sitting still are not your body adjusting. Those mean descend, immediately, at any hour of the night.
Three things that genuinely help:
- Walk slower than feels right. If you cannot hold a conversation, you are going too fast.
- Drink 3 to 4 litres a day. Unglamorous and effective.
- Take the acclimatisation days. The rest days at Namche and Dingboche are not padding in the itinerary. They are the itinerary.
Ask your doctor about acetazolamide before you travel. Plenty of trekkers use it, and plenty do not. That is a conversation for someone who knows your medical history, not for a blog post.
When is the Best Time to Trek to Everest Base Camp?
There are two good windows: March to May and late September to November. Everything else is a trade.
| Season | What you get | What you give up |
| Spring (Mar–May) | Warmer days, rhododendrons in bloom, climbing teams at Base Camp | Hazier long-range views, busy trails |
| Autumn (late Sep–Nov) | The clearest skies of the year, stable weather | Cold nights, heavy crowds in October |
| Winter (Dec–Feb) | Empty trails, very sharp views | Bitter nights, some lodges closed |
| Monsoon (Jun–Aug) | Green, quiet, cheaper | Rain, leeches lower down, frequent flight cancellations |
If I had one trip and wanted the mountain to actually show itself, I would go in the second half of October or the first week of November.
Why Does the Lukla Flight Leave From a Different Airport?
This one catches almost everybody. During peak season, flights to Lukla do not leave from Kathmandu. They leave from Manthali Airport in Ramechhap, a four to five-hour drive east.
The reason is congestion. Kathmandu has a single runway shared with international traffic, and Lukla only accepts flights inside a narrow morning weather window. Moving operations to Ramechhap, which sits lower and handles no international flights, lets airlines run several rotations in one morning with far fewer cancellations.
In practice, this means leaving your hotel in Thamel around 1:00 or 2:00 am. It is a miserable start to a trip. It is also the reason you are far more likely to actually fly on day one.
Build one or two buffer days into the return leg. Weather closes Lukla regularly, and a missed international connection costs a great deal more than an extra night in a lodge.
How Much Does the Everest Base Camp Trek Cost?
A guided package with a Nepali operator generally runs US$1,400 to US$2,500 per person, depending on group size, lodge standard, and whether the Lukla flight is included.
| Item | Typical cost |
| Both permits (Sagarmatha NP + Khumbu Pasang Lhamu) | NPR 6,000 (~US$40) |
| Lukla flight, round trip | US$400–430 |
| Guide, per day | US$30–40 |
| Porter, per day | US$20–25 |
| Teahouse room | US$5–15 per night |
| Meals | US$25–40 per day, rising with altitude |
| Wi-Fi, charging, hot shower | US$3–8 each |
Two things people underestimate. First, prices climb as you do, because everything above Lukla arrives by yak, mule, or human back. A plate of dal bhat that costs US$4 in Phakding costs closer to US$9 at Gorak Shep. Second, budget for tips. It is customary here, and it matters a great deal to the people carrying your bag.
Bring more cash than you expect to need. There are ATMs in Namche, but they run dry in peak season, and card payments above there are unreliable.
What Gear Actually Matters?
- Footwear: Broken-in boots with ankle support. Not new ones. The single most common trip-ruining problem I see is blisters from boots bought a fortnight before the flight.
- Sleep System: A bag rated to about -15°C. Lodges provide blankets, but rooms above Dingboche are unheated and nights drop well below freezing.
- Layers: Base layer, fleece, insulated jacket, waterproof shell. You will be sweating in the sun at 10 am and shivering by 4 pm on the same day.
- Sun: UV at altitude is punishing. High SPF sunscreen, lip balm with SPF, and category 4 glacier glasses, particularly for the walk across the moraine.
- Small Things That Matter: A power bank, because charging costs money and lodges lose power. A headlamp. Earplugs, since the teahouse walls are thin. And far more snacks from home than you think you need, because appetite disappears high up, and something familiar is occasionally the only thing you will manage to eat.
Almost everything else can be rented or bought in Thamel for a fraction of what it costs at home, especially down jackets and sleeping bags. Do not spend a fortune before you arrive.
One Last Thing Before You Go
The thing nobody warns you about is how quiet it gets. Above Dingboche, the trees are gone, the yak bells thin out, and for long stretches you hear nothing but your own breathing and the wind moving over the moraine. People come here for the mountain. What most of them carry home is that silence, and the faces in the villages they walked through to reach it.
Come slowly. The mountain is not going anywhere, and neither should you.
