Everest Base Camp and the Khumbu Valley: A Practical Trek Guide

What Everest Base Camp actually is

Sagarmatha National Park covers 1,148 square kilometres in Koshi Province and is commonly described as the highest national park on earth because Mount Everest lies inside its boundaries. Everest Base Camp, at approximately 28.0026, 86.8528, is the final point on the standard southern trekking route. The route from Lukla to base camp and back covers roughly 60 to 70 kilometres each way. Add the Gokyo extension and short walks around Namche, and a complete circuit is usually 120 to 150 kilometres.

South Everest Base Camp stands at 5,364 metres on the lateral moraine of the Khumbu Glacier. A moraine is the rubble deposited along a glacier's edge, so the ground is a mixture of rock, gravel, ice blocks and glacial dust. It is not a village, a resort or a viewpoint with a row of cafés facing Everest. The camp consists mainly of expedition tents, storage shelters, a few service structures and an area used for helicopter landings.

From April to May, the spring climbing season, base camp becomes a rough tent city. Expedition teams put up yellow, orange, blue, red and green shelters for sleeping, cooking and sorting equipment. Paths are worn between tents, generators run where possible, and porters carry loads through the camp. In October and November the settlement is smaller, but it remains busy with trekkers and support staff. Outside those periods there may be little more than a few tents and the mountain itself.

There is no summit view from base camp at all. The summit is hidden behind the Nuptse and Lhotse walls and the Khumbu Icefall. From camp you can see the glacier, the icefall and the lower faces of surrounding mountains, but not Everest's summit. The famous sunrise view belongs to Kala Patthar or, in some weather, Gokyo Ri. North Base Camp is in Tibet on the other side of the border and requires separate Chinese permission and travel arrangements.

“Base camp is a working gravel yard under a moving glacier. The summit is above the icefall, not in front of you.” Samar Sherpa, trekking guide, Namche

The Khumbu Icefall and why Everest is hard

The Khumbu Icefall is not a frozen waterfall. It is the steep section where the Khumbu Glacier descends from the Everest and Lhotse mass, running from roughly 6,000 metres toward 5,200 metres. Parts of the ice move about 3 to 5 metres a day. The glacier fractures into towers called seracs, opens crevasses and drops blocks that collect below as a rough field of ice.

Climbers leaving base camp cross the lower Khumbu Glacier and then enter the icefall on the route to Camp I at about 6,065 metres. From there the line continues over the Lhotse Face, across the South East Ridge, through the Bottleneck and onto the summit ridge. Serac collapse, hidden crevasses, rockfall and avalanche are part of the route. The icefall is the first serious technical section, but it is only one part of a climb that also demands glacier travel, fixed-line work, severe cold and sustained altitude.

The moving ice also explains the constant helicopter activity and the piles of expedition equipment at base camp. A closed route can reopen within hours, but it can also close without notice. The upper Khumbu is not a place where a weather forecast should be treated as a guarantee. For trekkers, the icefall is mainly a view and a reminder of the scale of the mountain. Climbers need a different set of skills, insurance and judgement.

Namche Bazaar is a trading town, not a theme park

Namche Bazaar sits at about 3,440 metres and is the largest settlement in the upper Khumbu. It developed as a trading town on the old route between Tibet and Nepal. Tibetans brought salt, wool and other goods, while Sherpa and Nepali traders dealt in grain, livestock, potatoes and manufactured goods. Tourism now supplies much of the income, but the town still functions as a supply centre for villages above Namche.

In practical terms, Namche has teahouses, restaurants, bakeries, pharmacies, gear shops, equipment rental, banks, an ATM, a post office and a helicopter pad. The ATM works often enough to use but fails often enough that you should arrive with cash. This is where most trekkers buy or confirm a Sagarmatha permit, cash in Nepalese rupees, replace batteries and stock a few days of snacks before going higher.

Most visitors treat Namche as an Instagram stop, take a short walk to a viewpoint and continue upward the next morning. A better use of the town is an acclimatisation day. Stay in Namche for at least one night, walk to Khumjung or Thamserk at a conversational pace, eat, sleep and do nothing demanding. If you develop a headache here, this is the right place to stay put and reassess, not the place to push on.

Teahouses and food above the trail

Teahouses provide the standard accommodation throughout the Khumbu. Most are family-run lodges with wooden or metal rooms, thin walls, shared bathrooms and blankets rather than central heating. In Namche, a basic room commonly costs NPR 2,500 to 5,000 per night. Above 4,000 metres, expect roughly NPR 1,000 to 2,500. Prices fall in some villages because demand is lower, but that is no guarantee of better heating or cleanliness.

Above 4,000 metres, the food can be better than many visitors expect. A hot bowl of thukpa or a plate of dal bhat costs about NPR 600 to 1,200, fried noodles or rice cost NPR 500 to 1,000, and garlic soup is usually NPR 300 to 600. These are simple meals, but they are hot, filling and generally more useful than a large dinner after a day of walking. Menus become narrower higher up, and meat is expensive and not always available.

Tea costs around NPR 200 to 400. A hot shower, when the lodge has one, commonly costs NPR 300 to 800. Device charging and Wi-Fi are often charged separately at NPR 200 to 500. Bottled water can cost NPR 300 to 600, so ask about treated or boiled refill water. Rooms usually have electricity but no reliable heating, and a mobile signal can disappear for hours. Carry a headlamp, a charged power bank and enough cash for the higher villages.

Porters, loads and daily rates

Porters carry group tents, kitchen equipment, food, fuel and expedition gear, and they may carry a trekker's duffel if the load remains within the permitted limit. Regulations set a maximum load of 20 kilograms. A porter should have proper boots, a rain jacket, warm layers and insurance. If a porter is offered a 30-kilogram load, old footwear and no insurance, the agency is taking the savings from the person doing the work.

The Nepal Trekking Agents Association, or NTAA, has been the main industry reference for trekking wages, while local porter associations may quote separate rates. Its last widely published minimum set a licensed guide at US$30 per day and a porter at US$25 per day. For a 2025 trip, many operators were budgeting US$35 to US$40 for a guide and US$30 to US$35 for a porter. Ask the agency for the current card in writing and establish whether rest days and weather delays are paid. These are wages, not tips.

A gratuity of roughly 10 to 15 percent of the agreed wage is normal for good service, but it should not be used to excuse a below-standard rate. Book through a registered agency rather than hiring someone informally at the airport. Ask to see the porter's insurance and equipment, and do not assume every person carrying luggage is a licensed porter. Walking at the group's pace is also part of the porter's job, so a group that routinely leaves its workers behind is treating them badly.

The 13-to-15-day walking altitude schedule

A workable 13-day walking plan from Lukla looks like this: Day 1, fly to Lukla and walk to Phakding at 2,610 metres, usually 3 to 4 hours; Day 2, trek to Namche at 3,440 metres, 5 to 6 hours; Day 3, rest in Namche; Day 4, walk to Deboche at 3,820 metres, 6 to 7 hours; Day 5, continue to Dingboche at 4,810 metres, 3 to 4 hours. Day 6 crosses to Everest Base Camp at 5,364 metres, then descends to Gorak Shep at 5,170 metres, taking 4 to 5 hours including time at the camp.

Continue with Day 7 for Kala Patthar and a descent to Lobuche at 4,950 metres; Day 8 for rest and an acclimatisation walk near Lobuche; Day 9 for the walk over the pass above Dzongla to Gokyo at about 3,850 metres, normally 6 to 7 hours; Day 10 for Gokyo Ri and the lakes, 4 to 6 hours; Day 11 to Thame at 3,800 metres or Chhukung at 3,700 metres; Day 12 to Namche; and Day 13 to Lukla, 6 to 7 hours if the weather behaves. Days 14 and 15 should remain available for a missed flight, a trail closure or a medical delay.

Sleeping elevation matters more than the highest point reached during a day. Above 3,000 metres, most people do well when their sleeping altitude rises by no more than about 500 metres per day, with a rest day every three or four days. Above 4,000 metres, many trekkers cope better with 300 to 500 metres. A route can involve 1,000 metres of climbing and descending while the night's altitude gain remains modest. Do not add an extra pass because the map makes it look easy, and do not ascend if you have symptoms.

Gokyo, the lakes and the quieter alternative

The Gokyo route branches from the base camp circuit at Lobuche and crosses a high pass near Dzongla before descending to Gokyo. The walk is roughly 12 to 15 kilometres and takes 6 to 7 hours. Gokyo sits at about 3,850 metres, with lodges beside the largest lake and a cluster of higher lakes within a day's walk, including Dud Pokhari, Thagnak Pokhari and Cho Pokhari. Lake levels vary, and the main Gokyo Lake can dry during parts of the winter and spring.

Gokyo Ri rises to about 5,333 metres on common maps. The climb gives a broad view across Everest, Nuptse, Cho Oyu, Machapuchhre, Kangtega and Lhotse. It is not always a clearer view than Kala Patthar, but the combination of peaks, lakes and lower foot traffic is often better. On a clear October or November morning, Gokyo and Gokyo Ri often draw fewer than half as many visitors as Kala Patthar and the base camp trail. There is no fixed daily count, and spring-season crowds can be similar.

The lodges in Gokyo are basic, with shared toilets, intermittent solar power and limited menus. Book ahead during the spring season, but confirm that your lodge will still be operating in late October or November. The Gokyo route also has its own altitude demands, so it is not automatically safer merely because it ends lower than base camp. It is a useful alternative when you want mountain views without turning every morning into a crowded walk.

Kala Patthar at sunrise

Kala Patthar reaches 5,545 metres and stands about 1.5 to 2 kilometres above Gorak Shep on the walking path, with roughly 370 metres of ascent. The normal round trip takes 4 to 5 hours. For sunrise in late October and November, leave Gorak Shep at 4:30, reach the viewpoint around 6:00 and expect sunrise at approximately 6:10 to 6:30 Nepal time. Groups can make the ridge look busier than it is, so an earlier start reduces the queue on the final section.

There is no honest, fixed percentage for a clear sunrise. The Khumbu forecast covers a huge area, and cloud can move in or lift within 30 minutes. In late October and November, a clear horizon is common enough to make the climb worthwhile, but it is not guaranteed. A useful test is the cloud level: if low cloud sits below about 4,500 to 5,000 metres, the peaks will remain hidden no matter how long you wait. Any operator promising a guaranteed summit view is selling a slogan, not reliable weather advice.

The cold is the part people underestimate. Air temperature can fall below minus 15 degrees Celsius, and wind can push the wind chill below minus 25 degrees even when the thermometer reads less severe. Wear insulated gloves, a hat, a balaclava, a down jacket and a windproof outer layer rather than relying on a fleece. Carry water and food because the exposed ridge is cold even when the walk from Gorak Shep felt easy. If winds are strong or visibility is poor, turn back. A safe return is worth more than a photograph taken through cloud.

Kala Patthar and monastery access rules

A foreign visitor needs the Sagarmatha National Park entrance permit, which costs NPR 3,000. It covers the normal routes to Everest Base Camp, Gokyo, Kala Patthar and Tengboche Monastery. There is normally no separate Kala Patthar entrance ticket. The permit can be arranged through an agency or obtained at the park checkpoint, but carry the passport used for the permit and be ready for a checkpoint inspection.

Monastery rules are less consistent. Tengboche, the largest monastery in the Khumbu at about 3,670 metres, usually asks for a donation or entry contribution of roughly NPR 100 to 500, and some monasteries add a camera charge of NPR 100 to 500. Carry NPR 500 to 1,000 in small notes rather than assuming there is a card terminal. Opening times commonly run from morning to late afternoon, but religious ceremonies, repairs, funerals and local events can close the main buildings without advance notice.

Do not rely on an old blog or a map for access. Paths can close after landslides, snow or trail work, and local authorities can impose temporary restrictions that are not posted online. Ask the Sagarmatha park office in Namche, the local municipality or the lodge where you slept on the previous day. Do not fly a drone in the park without prior permission, which is rarely granted to visitors. At a monastery, ask before photographing monks or entering prayer rooms, and do not treat an active place of worship as a photo set.

Lukla, the flight in and the walk from Solukhumbu

Lukla airport is at 2,860 metres and has one short runway of roughly 460 metres surrounded by steep hills. A scheduled flight from Kathmandu takes about 30 to 45 minutes in good conditions, although the full airport process often takes three to six hours because aircraft are held for weather. One-way fares are commonly NPR 18,000 to 35,000. Most airlines impose a combined baggage limit around 15 kilograms, so check the carrier's current rules and ensure your duffel does not exceed the allowance.

Wind, cloud, poor visibility and aircraft congestion cancel Lukla flights regularly. A cancelled flight is usually rebooked for the following morning, not later the same day. Do not connect a Lukla flight with an international departure on the same afternoon. A charter helicopter flies in about 25 to 35 minutes and costs roughly NPR 120,000 to 190,000, but it is also affected by cloud and should be considered for a genuine emergency rather than a missed connection.

The walking alternative starts in Solukhumbu at about 2,336 metres. A route through Kharikhola and villages such as Tamrang, Chumling or Sujikhar reaches Lukla in roughly 50 to 65 kilometres and three or four walking days, depending on the village route. It is not a day hike from the road head. If the Lukla flight is cancelled, this can absorb one or two days without losing the whole trek. From Kathmandu itself, the walk takes about 9 to 12 days, so consider a bus to Bandipur or another lower trailhead and add more buffer.

How long to allow

Allow 13 walking days for the standard Lukla, base camp, Gokyo and return route, then keep two reserve days in the plan. One reserve day is sensible for a cancelled Lukla flight, while the second covers trail delays, a lodge closure or a slower descent. Book the first and last nights in Kathmandu separately from the trek. If you fly into Lukla, arrive at least a day before your first scheduled trek day, and never treat the last day as the same day as an international flight.

Total walking time normally falls between 70 and 100 hours, depending on the group, side walks, weather and the number of rest days. The route is not technically difficult, but the altitude, load and uneven stone steps make a fast pace wasteful. At 4,000 metres and above, five hours of walking can feel like a full day. Choose a schedule that can absorb a delayed start rather than one that only works in perfect weather.

When to go

Late October to late November is the best season. The atmosphere is often clearer than during the spring rush, the jet stream is less disruptive, and the lower winter snow has not yet reached its peak. Cold remains a factor, especially before sunrise, and some lodges begin closing in the second half of November. Book Gokyo and any lodge near the end of the route, then confirm it is still operating shortly before you arrive.

Late March to mid-April is the other practical window. It is warmer but busier, with more tents at base camp and less lodge space. December through February can provide excellent clear-air views, but the trail may be covered in snow, some lodges close, and winds can be severe. The June to September monsoon is a poor trekking choice because of rain, swollen streams, landslides and flight disruption. Late September and early October can work, but conditions become less predictable as the season changes.

What the trek costs

The Sagarmatha permit is NPR 3,000. A basic room for 12 to 14 nights usually costs NPR 25,000 to 45,000, while food, water, tea, showers, charging and Wi-Fi add another NPR 25,000 to 40,000. An independent trek using a porter but no guide is roughly NPR 85,000 to 125,000 before flights, insurance and equipment. Adding a licensed guide usually brings the total to about NPR 130,000 to 185,000.

Agency packages for 13 to 15 days commonly start around US$700 to US$1,000 with a local operator and run from about US$1,000 to US$1,600 for a stronger guide and better support. Premium operators can charge more than US$2,000. The package should state the guide and porter daily rates, the number of included rest days, meals, permit, emergency support and exactly what happens if a flight is cancelled. A low quote that excludes meals, porter wages or an acclimatisation day may be cheaper only because the missing costs appear later.

Kathmandu to Lukla flights usually add NPR 36,000 to 70,000 for a return. Travel insurance commonly costs US$40 to 100 and should cover medical treatment and helicopter evacuation to at least 5,500 metres. A rescue policy with a low evacuation cap is not adequate for the Khumbu. Tips are extra, and insurance claims often require the guide or agency to coordinate the rescue and guarantee payment.

How to reach Lukla and what to do when the flight fails

The normal arrival is a morning flight from Kathmandu, followed by lunch in Lukla and a short walk to Phakding. If the flight is cancelled, ask the airline for the next available departure and use the wait to eat, rest and check that your permit and cash are in order. Do not spend the waiting period walking to Namche; the first flight often lands close to midday, and rushing uphill after a delayed night is poor acclimatisation practice.

If the delay lasts more than a day, use the Solukhumbu walking route or transfer to a lower trailhead by bus. A helicopter should be reserved for medical necessity, not used to protect a tight international connection. Keep your trekking kit ready to move without two days of repacking. A spare fleece, dry socks, water and snacks are more useful in Lukla during a delay than a day of sightseeing.

Where to stay and where to eat

Use teahouses throughout the route rather than carrying a tent and full kitchen unless you have real backpacking experience. Established options in Namche include Hotel Tibet, Hotel Everest View and several smaller family lodges. Tengboche Lodge is the standard stop below the monastery. Gokyo has Gokyo Lodge, Dragonfly Lodge and other lodges around the lake. In Lukla, Hotel Everest View, Hotel Himalayan Slate and Khumbu Yhool are long-standing options. Ownership, tariffs and opening dates can change, so confirm before relying on a specific property.

Above 4,000 metres, eat where there is a kitchen rather than carrying lunch for every day. Dingboche and Pheriche usually offer better ingredients and prices than the temporary food stalls at base camp. A hot dal bhat, thukpa or garlic soup costs about NPR 600 to 1,200. Order dinner the night before if the lodge is remote, keep snacks from Namche and do not expect a restaurant to be open when you arrive late.

Base camp accommodation is usually expedition camping rather than a normal teahouse room. Unless an expedition package includes it, sleep at Gorak Shep, Pheriche or Lobuche after visiting base camp. You will save money, get better food and still reach the glacier. The only reason to remain at the camp is if the expedition team has specifically arranged it.

What to carry and what to leave behind

Bring a layered system: a quick-drying base layer, light fleece, insulated down jacket, waterproof shell and trekking trousers. Add insulated gloves, a warm hat, sun gloves, sunglasses rated for strong alpine light and a brimmed sun hat. Late November may require microspikes, especially around Kala Patthar and shaded sections after snow. A headlamp with spare batteries is essential, and a full-day water bottle should be paired with a bladder or a second bottle.

Pack a first-aid kit, blister treatment, personal medication, hand sanitiser and a basic sleep cover. Trekkings poles help on stone steps and save your knees. Teahouses provide blankets, so most walkers do not need a heavy sleeping bag, although a silk liner is useful. Do not bring an inflatable mattress for the standard teahouse route unless you have confirmed that the lodge provides one. Leave room in your duffel for the porter's load, and check the airline baggage limit.

Water purification matters more than carrying every drink from Kathmandu. Refill stations and treated water are available at many lodges, but the supply and treatment method are not always consistent. Use your own purifier, boil water or buy sealed bottles when uncertain. Avoid an oxygen bottle as a substitute for descending. An oxygen canister can support a rescue, but it does not make continued ascent safe when a person has altitude illness.

The warning worth reading: a headache can become a brain emergency

Cold is the problem most people prepare for and can usually manage. The dangerous pattern is a headache that becomes a brain illness. Acute mountain sickness may begin as a headache with nausea, dizziness, unusual fatigue or poor sleep. If the headache gets worse despite rest, fluids and a normal painkiller, stop ascending. Confusion, unusual behaviour, hallucinations or inability to walk in a straight line can mean high-altitude cerebral edema. A person who cannot walk heel to toe needs immediate descent, not a stronger painkiller and a warmer sleeping bag.

Breathlessness at rest, a persistent cough, chest tightness, blue lips or frothy pink sputum can indicate high-altitude pulmonary edema. It can appear without a severe headache. The response is also immediate descent, oxygen if available and evacuation by helicopter when necessary. A helicopter cannot fly through the same cloud that stopped the landing, so descent on foot must remain the first plan. Keep the sick person with a companion and never leave them alone in a lodge.

Never ascend with a headache that is getting worse. If someone is walking in a circle or cannot walk straight, get them down the mountain now.

Everest Base Camp and the Khumbu Valley, Nepal

For the Khumbu, descend by at least 500 to 1,000 metres and reassess. Acetazolamide can reduce the risk of acute mountain sickness when prescribed for the right person and dose, but it does not make an unsafe ascent safe. Carry a satellite communicator if the trip budget allows, since mobile coverage is inconsistent. Teach the group the symptoms before reaching Dingboche, since decision-making becomes harder when several people are tired and unwell.

What to avoid on this trek

Avoid adding passes to fill spare days, skipping the Namche rest day or rushing above 4,000 metres. Do not follow a schedule that requires gaining more than about 500 metres of sleeping altitude on consecutive days. Avoid alcohol and sleeping pills, which worsen dehydration and can mask important symptoms. Do not leave a symptomatic person in Namche, Dingboche or Pheriche because the weather looks bad; their descent may become harder as they weaken.

Avoid booking an international flight for the same day as the planned return from Lukla. Do not buy a permit from an unofficial broker without a receipt, and do not accept a porter without equipment and insurance. Do not assume a helicopter will arrive. Do not photograph monastery ceremonies without permission, fly a drone or leave food for ravens and marmots. Most importantly, treat a worsening headache or breathlessness as a reason to go down, even if that means missing Kala Patthar, Gokyo or the summit view you paid to see.
