Is this your ideal trek?
Trekking in the Everest region is all about altitude. By its very nature adventure travel involves that you be prepared for the unexpected. In far-flung and developing countries do not expect standards you are used to at home. Remote areas are sometimes unpredictable and itineraries may be altered. To enjoy your trip and get the most out of your adventure it is important that you are flexible, positive, and eager to take on all the challenges that arise from your Everest base camp odyssey. If you’re a greenhorn in the wilderness world then this trek would be ideal for you.
To truly enjoy this trip, you should be pretty habituated to walking 4-6 hours each day for several days on the go while some days will be relatively longer. We encourage you to walk at a pace that suits you without any rush whatsoever. This is a key aspect of enjoying such trips in the planet’s most popular region. You ought to be physically fit and an active walker to get the best of this classic mountainous journey to the south side of the mighty Everest.
General information important to this trip:
TREKKING AT HIGH ALTITUDES (over 3500m)
This trip includes strenuous trekking at altitudes of over 3500m. For us, altitude is a very serious issue, a result that has kept our records clean making us one of the best adventure operators in Nepal for over 30 years of operating treks in the region. Our trekking guests must be in great health and have high fitness levels to attempt this trip, as well as be committed to training to ensure you are suitably physically prepared for the tough challenges that go above 4500m.
Altitude sickness is a risk for anyone, including on the Annapurna, Langtang, and Everest Base Camp treks. Please make sure you familiarise yourself with signs and symptoms before you depart and monitor your own health during your trek, without letting it worry you.
We advise all our guests to undergo a thorough medical with their personal physician before they embark on this trip.
Participating in a group trip
When you travel with a group you will find much camaraderie and all the fun and also there’s bound to be some of the frustrations of traveling in a group. Your group mates will probably come from all corners of the world and you will come across a range of age groups too. We ask you to be understanding of the various needs and preferences of your group - patience with your fellow travelers is sometimes required for the benefit of everyone's travel experience. Remember too that you have responsibilities to the group. If you are requested to be at a place at a certain time, ensure you’re on time without keeping the rest of the group waiting. Experience has taught us often that the very best trips we operate are those where the chemistry within the group works well - this simply requires a ‘give a little take a little’ attitude effort on your part. For privacy reasons, we are unable to provide you with contact details and any personal information about your fellow travelers booked on your trip prior to departure.
TRAVELLERS who prefer going SOLO:
Our group trips are generally planned for shared accommodation and don't involve single supplements. Single travelers share with people of the same gender in accommodation ranging from twin to multi-share. Some of our itineraries have accommodation booked on a mixed gender share basis [for couples or trekkers known to each other prior to the trip]. On a selection of our trips, you have the option to pay a single supplement to ensure that you have your own accommodation (where available). Please note that this only applies to accommodation during the trek - pre-trip and post-trip accommodation will be booked on a single-room basis at your hotel in Kathmandu. We also have arrangements for guests who wish to trek completely solo out of the group.
when booking with Himalaya View Treks, it’s a condition upon joining any of our trips where all clients must be insured for comprehensive expenses that might incur due to medical issues or accidents (this includes air ambulance, helicopter rescue, and treatment costs). Please note that we don't arrange or sell insurance because such a system is not allowed in our country.
Our Cost versus the Experience
At Himalaya View Treks, we always go the mile to ensure our trekking guests get the best experiences of the trip with maximum comfort and safety on a ratio that goes beyond the cost that we charge for the trip. We provide a ‘no frills’ price with breakdowns to make sure our client are getting the best for a cost that goes beyond all expectations
Tipping [an expectation on such risky arduous trips]
Tipping is very much part of the culture in Nepal and although entirely at your discretion, it is usually expected. Often people would like to tip in recognition of good service but are unsure how much would be appropriate in a foreign country - for this reason, we have listed guideline amounts below (these are intended as a guideline only and you may see fit to give more or less depending on the service that you have received).
For the tipping of your trek staff and your tour leader, we suggest passing an envelope for each staff member around the group so that everyone can put in what they feel comfortable with anonymously.
The following are guideline amounts received by each staff member from the group as a whole...
- Tour Leader: Rs30, 000 - 35,000 (usually tipped on the last night in Kathmandu)
- Your trekking crew (tips are usually given on the last evening of the trek in Lukla):
- Head Trekking Guide and Assistant Guides: Rs20, 000 - 25,000 for each guide
- Trek Porters/yak men: Rs10, 000 for each porter or yak man
Acute Mountain Sickness [AMS]
When we ascend above 2500 metres our bodies have to acclimatise to the decreasing amount of the oxygen available. So, to allow our bodies to adjust we have designed our treks in ways that help you ascend slowly, allowing acclimatisation to occur when you go above the tree lines where the air is thinner. However, during the acclimatisation process, you may experience some of the following symptoms.
- Disturbed sleep patterns
- Loss of appetite/nausea
- Shortness of breath
- Swelling of the hands and face
But if you feel such symptoms don’t let it worry because it’s normal. Individuals acclimatise at different rates. Some may experience symptoms, some may not. Your best strategy is to take your time and drink plenty of water. These symptoms may not indicate the onset of A.M.S. and if you experience them it does not necessarily mean that you should not continue. All our group leaders have extensive first aid training and we urge you to communicate with the group leader at all times should you believe you have any symptoms in order that we can effectively monitor your symptoms as you go higher. The only cure for Acute Mountain Sickness is to descend. Please note, that your group leader has ultimate responsibility and may ask you to descend if symptoms persist. As a last resort, if matters grow from bad to worse, we always have a helicopter on standby for immediate evacuation.
A Typical Day on the Everest Base Camp Trek
A typical day on the trail begins with a wake-up call at around 6 AM by your guide. Freshen up and get ready. Pack your belongings and head to the dining area for breakfast by 7 AM. Check your luggage for the final time and fill your water bottle before you hit the trail by 8 AM, along with your guide.
To avoid walking in the heat and enjoy clear mountain views, you make an early start. En route, there will be short breaks to enjoy the views and take photographs. You haul up for lunch at a local teahouse around noon or mid-day. After a quick rest of about an hour or 40 minutes, you get back on the trail and continue till you reach your overnight stop.
Upon reaching the stop for the night, you head to your teahouse, check in, and have some rest. Tea with some light refreshments (cookies or biscuits) will be served at 5 PM. As the rooms are not insulated, you can warm yourself by the heater or stove in the communal area.
Exchange stories or play cards with other trekkers and sherpas till dinner is served (around 7 PM). After dinner, your guide will brief you about the next day’s trek – the route you will take, difficulties, where you will stop for lunch, etc. Afterward, retire for the night and have a well-deserved rest.
On average, you may have to walk 6 to 7 hours daily. The trek to Phakding is the shortest and the easiest, while the hike to Everest Base Camp from Dukla lon the 5th day could be your toughest. On Day 6, a hike to Kalapathar for the sunrise view is scheduled. So you will have to wake up before 4 AM to reach Kalapathar before sunrise. Your guide will share the details regarding the hike during the after-dinner briefing on Day 5.

The weather forecast says rain/clouds/snow in Lukla on our Flight Day. Are we in for a rough flight?
When you are up on the mountains in Nepal, we would suggest you be ready for anything. You’re about to trek on some of the most rugged territory on earth, despite its extraordinary beauty. Weather forecasts for Lukla are never correct and different sources will give you different information. If it is a really bad day in terms of weather, the airlines will themselves cancel the flight and you might have to wait till the weather clears. Yes, flying in high altitude is never easy, even on a clear sunny day; the plane might face turbulence because of the wind blowing from the mountains. But overall the flight to Lukla is very exciting and it’s an experience that you will never forget.
What temperatures can you expect at the EBC during spring and autumn?
These are the best months to do this trek, as the weather is mild and the temperatures range from 12 to 15 degrees. The skies generally remain clear and the days are pleasant and warm. You can expect an occasional spring shower and hazy weather during spring. The mountain views are stunning in September, as there is more snow on the mountains. Nights can be freezing as the temperature dips after sun down.
How much do you reckon I will need to spend on the trail per day?
If you have booked a package with us you won’t be spending much as accommodation and 3 meals are already included in your trip price. You may have to personally pay for items like beverages and drinks, extra snacks, hot showers, electronic device charging, wifi etc. USD 20 to 30 (NRS 2000-3000) per day will be more than enough you may need to spend in a day.
What do you recommend for water along the Everest trek?
You can either buy bottled mineral water or fill up a reusable water bottle with boiled or sterilized water. During the trek, the teahouses or lodges serve you bottled and filtered water which is generally safe and has to be paid for. A liter of water would cost anything between 1 to 4 USD. As you go higher the cost of all commodities, including water, increases. But do note there is no dearth or scarcity of drinking water at teahouses. We encourage our guest to use iodine and other purifying agents to treat the water before drinking. You need to drink at least 3-4 liters of water each day to stay hydrated at higher altitudes. Keeping your body hydrated helps you to keep away the symptoms of altitude sickness. Please note, the company doesn’t provide drinking water or any extra drinks or beverages other than the ones that are specified in the trip cost.
How much tips should I give to the guide, porter and driver?
While tipping is not mandatory it is a nice way of showing your appreciation to the people who have helped you enrich your holiday experience. It all depends on how far you are pleased and satisfied with their services. There is no fixed amount, but many of our clients offer 8-10 percent of the total tour price as tips.
Is it hard to climb Everest Base Camp?
You need to be in good shape and have an ability to walk 6–7 hours uphill and downhill per day. This trek is suitable for passionate trekkers. Positive attitude, excellent health, and strong determination are required for be successful on a trip of this kind. Past hiking experience would be an asset but no technical skill is required for this trip. Besides, it is advisable to trek with a highly reputed trek operator who knows what it’s like in this part of the world, with experienced guides who can help you with significant mental preparation to keep you going all the way, as tough as it gets. Regarding the difficulty, the only challenging factor is the altitude. Our Everest Base Camp trek itinerary provides ample time for acclimatization. Neither ropes nor ice picks are needed for this trip and no vertical climbs are involved. Greenhorns in good physical shape, who exercise regularly, has positive attitude and has healthy heart and lungs can easily complete this adventurous trip.
How long do we stay at Everest Base Camp? Can we spend the night at the Base Camp?
As Everest Base Camp is situated at a high altitude of 5,364 metres, you spend only 1 to 2 hours at the camp. Since the base camp lies at the foot of the world’s tallest mountain Mount Everest, the hike to EBC is probably the highlight of your trek. Though one cannot view the summit of Mount Everest from the base camp (as the mountain is too huge) you can get close up views of the massive walls of Everest, Khumbutse, Lingtren and Nuptse. The Khumbu Icefall appears spectacular. Though the icefall lies close to the Base Camp, it is not possible to explore it as you need proper climbing gear to walk on it. But you get to explore the actual base camp of the Everest expedition groups. During climbing season, it is like a mini city of tents and you get to meet mountaineers (sometimes celebrities too!) from different countries attempting to summit Mount Everest. After taking pictures and soaking in the magnificent views you descend down to Gorak Shep again. Please do note the visibility of mountains depends on the weather. If it’s foggy you may not get good views of the mountains. No, we do not spend the night at Everest Base Camp as there are no teahouses or lodges there. Moreover it is advisable and more comfortable to spend the night at a lower elevation. After enjoying the views we trek down to Gorak Shep and stay overnight at a local teahouse.
Can you see the summit of Mount Everest from Everest Base Camp?
No, the summit of Mount Everest is not visible from Everest Base Camp. Rising above 8000 metres, the mountain is just too gigantic to be viewed in its entirety from its base. The summit of Everest can be viewed from Kalapathar and from places en route to EBC. If you want to view Mount Everest without having to trek to Everest region, you can do it by driving to Nagarkot, taking an Everest Mountain Flight and an Everest Base Camp Helicopter Tour. The best views you get of Mount Everest is from Kalapathar. It leaves you breathless, virtually!
What sort of toilet facilities will be available on the Everest Trek?
In all our Everest Treks the teahouses that we use have western toilets. In luxury lodges and teahouses in the lower elevations the rooms come with attached bathrooms and hot showers. At higher elevations the facilities may be a bit basic and you may have to share the bathroom with other travellers. Please do note that in case of extreme cold, the water in the toilet basin may freeze and you may have to use an Asian (also known as ‘squat’) style of toilet that is located outside. Please do carry toilet paper rolls with you at all times. It is important that you carry enough rolls of toilet paper and hand sanitizers while trekking. Can I make payment with my credit card or with my cash while Everest trekking? You need to have local currency to purchase items on the trail. While Lukla and Namche in the Everest Region may have lodges that would accept payment with cards, we strongly advise to carry enough local cash with you to buy essential items en route. You can exchange your currency at any of the money exchange centres in Kathmandu or use your credit or debit card at the local ATMs to get local currency.
Where can I store my extra luggage while trekking?
You can store it at your hotel (most hotels in Kathmandu have storage facilities) or you can leave it at our office.
Is there WIFI available on the Everest Base Camp trail?
Yes, wifi hotspots are available on the Everest Base Camp trail. But please do keep in mind, due to the mountainous terrain the network maybe erratic sometimes. Often times the signal gets lost or the strength is poor.
