Best Time For Everest Base Camp Trek

The best trekking season for the Everest Base Camp is spring (March to May) and autumn (September to November). These two seasons provide the best weather and climatic conditions for trekking in Nepal.

Spring season (March to May)

Spring is one of the most favorable times for Everest Base Camp Trek. It has pleasant weather with long, sunny days. The temperature is also mild and ideal for trekking. The average daytime temperature is around 20 degrees Celsius, while the nighttime temperature can get up to -5 degrees Celsius. Due to the low precipitation level, the trails are dry, and visibility is also brilliant. Another great thing about EBC Trek in spring is to witness the blooming forests of rhododendrons and colorful Himalayan floras.

Autumn season (September to November)

The crisp autumn air also offers perfect weather for a comfortable trekking experience. The weather is stable and moderate at this time of the year. Moreover, the rain in the prior season cleanses the surrounding vegetation and landscapes, so visibility is excellent. Autumn is also a festive season. The daytime temperature can reach up to 25 degrees Celsius. Meanwhile, the nighttime temperature can drop to -10 degrees Celsius.

Difficulties During 10 Days Everest Base Camp Trek

The trail to Everest Base Camp is not easy. It is a moderately challenge trail that is physically and mentally demanding. During the trek, you will walk on stone staircases, forest pathways, suspension bridges, and rocky and glacial terrains. Similarly, you will have to make steep ascends and descends. The average daily walking hours is between 5 to 7 hours. Thus, the trek requires good physical fitness, strength, and stamina. 

As you ascend to higher elevations above 2500 meters, the risk of altitude sickness also increases. Trekkers may experience various symptoms, which can range from mild to severe. Hence, it is crucial to take proper acclimatization and precautions to minimize the risk. Another difficulty during the Everest Base Camp Trek is the unpredictable weather. The weather in higher elevations changes rapidly, adding more challenges during the trek.

Aside from the physical challenges, the journey to Everest Base Camp also poses mental challenges. The remote trails, lack of infrastructure, and unfamiliar terrains can make trekkers feel isolated. It can mentally stress and drain you. Although the Everest Base Camp is a moderate trek, it requires proper physical and mental preparation.

Accommodation and Meals 

You will not find luxurious hotels and stays during the 10 Days Everest Base Camp Trek. You will mostly find teahouses, lodges, and guesthouses along the routes. These accommodations provide only basic services and limited amenities. They provide beds, blankets, pillows, and bedsheets. The rooms are usually on a twin-sharing basis with communal bathrooms. You must pay extra fees for internet, phone calls, hot shower, charging, etc. The trek package does not cover these additional costs. 

Various food options will be available during the 10 Days Everest Base Camp Trek. Since Dal Bhat is a Nepalese staple food, you will find it at every eatery and teahouse. Similarly, you will also find various other cuisines, including Western menus. The package covers three meals (breakfast, lunch, and dinner) during the trek. The standard meal comes with a choice of beverage (tea or coffee). The other additional meals and beverages are the trekker’s own personal expense.  

Some meal options include oats, porridge, bread (Tibetan/ chapati), momo, thukpa, Sherpa stew, soups, salad, pasta, spaghetti, curries, and many more. At higher elevations, it is best to avoid dairy products, caffeine drinks, hot chocolates, and alcoholic beverages.

Everest Base Camp Treks

Trek au base camp de l’Everest avec un guide très sympathique et serviable, Ranja Tamang. Étant solo, C’était important d’avoir un guide sympathique avec qui partager plusieurs jours. J’étais chanceux d’avoir eu droit à des vues magnifique. À refaire pour faire les Three Passes ! Trek to the base camp of Everest with a very nice guide, Ranja, i had an amazing time with him. Being solo hiker, it was very important to have a nice guide. I was also lucky to get amazing views on Everest and Nuptse and a lot of mountains. I will definitely come back to try the three passes trek or trek in another region in Nepal

Private trek with Raj (Gokyo + Chola Pass + EBC)

Our 13-day trek was beyond amazing, all thanks to our guide Raj, porter Budhha and managing director Sappa. We were very impressed with how everything was so well organized, it seemed like every little detail was covered (hotel/airport pick-up, flights to/from Lukla, tea houses, food, day to day itinerary... literally everything!). Raj made every effort to ensure we enjoyed this experience, he was very attentive to our needs, knowledgeable about every aspect of the trek, and even tried to lift our spirits when things got tough. We couldn't be more grateful for this rewarding experience.

Spectacular Gokyo Ri

Just completed the Gokyo Lakes trek with NBCT and couldn’t recommend them more highly. Sappa made communication and logistical arrangements very easy. I’ve now done 2 treks with my guide Surcha Tamang and we’ve become firm friends. He looks after his clients extremely well and has strong relationships with all the tea houses in villages enroute which makes meals, accommodation etc very easy. Surcha takes his responsibility very seriously and ensures a safe and carefree trip from airport pickup to airport drop off. You should book with NBCT and request Surcha if you can get him!

Exceptional Everest Base Camp Trek with Nepal Base Camp Treks

I am John from England and I stumbled across the Nepal Base Camp Treks Pvt.Ltd while surfing on the internet for my Everest Base Camp Trek. With so many tour agencies to choose in Kathmandu, It was quite hard to spoil for choice- but finally decided to go with Nepal Base Camp Team because they simply stood out excellent reviews and a 100% customer care satisfaction. To me and my team, that was very impressive and I and my team do not regret our decision. On the based of positive reviews, We already had a high expectation from Nepal Base Camp Treks and each and every expectation our team had were simply met with such grandiosity that the company really deserves all of the praises it gets. NBCT made us have a wonderful experience right from the start to end. Sappa Lama was very quick and prompt in his email responses and was always happy to respond to the silliest of our inquiries a very patient man with an excellent customer service focus. For Nepal Base Camp Team, their customers come first and they will be ready to go to lengths to make sure their customers safe and well looked on the mountain and in a city. They employ the best guides and porters in the mountain. I and my team did the Everest Base Camp Trek (5364m/17,594fts) accompanied by my guide Pawan Tamang, who made sure that our team had a wonderful lifetime experience in Himalaya. A polite person and very knowledgeable about the Sherpa culture and Tibetan Buddhism, Pawan has the maturity to take the responsibility of his customers in the mountains. from Luka to Lukla throughout my trek, Mr.Pawan was in the front and my Porter Temba at the back. They are always made us sure never slipped or took a wrong step and informed us to stay mountain sidewalk all the time. They ask you to enjoy the freedom you want in the mountains, taking as many rests and catch photo stops as you want. Pawan took to take care of me and my team Joana in every lodge, bringing us a hot bowl of water in the mornings so that I and my team could wash our faces and teeth. Believe me, it is very cold up there above 4000m that without hot water I would be feeling pretty hard throughout the day! These acts of care and concern that really made our trek wonderful and amazing. Overall, we all team can vouch for one-step-ahead for Nepal Base Camp Treks and their mountain guides and porters. in my opinion, their customer focus makes them stand apart. Even when things go wrong, like bad weather or flight delays, or your sickness, they never complain and put the first priority on their customers first. It was the best care that we were shown that have won our heart over by the company. It was such a memorable treat to be with them and to experience the beautiful Himalayas with a helpful and cheerful mountain guide who made sure that we were all right at each and every step on the way. Mr. Sappa Lama and Mr. Lako Lama were also just a phone call away in the office at Kathmandu, giving us the reassurance that everything was going to be all right and that we were in good hands. Thank You so much Nepal Base Camp Treks for such a fabulous time in the Everest region, showing such a best customer care that all the time and we will back again sometime in future with our family

Amazing Family Adventure in Nepal

In October 2015 I went to Nepal for the second time. This time I decided to take my family along, because my previous experience with Sappa and his team was so great, that I had no worries about taking my children to Himalayas. We spent almost 4 wonderful weeks of travelling, hiking and gaining cultural experience. My children loved Nepal, learned a lot about this wonderful country. I can highly recommend a family trip to everybody who is at least a bit fit and open-minded, it is a lifelong experience! We are all definitely coming back.

Highly Recommend Sappa for EBC Trek

I trekked with Sappa to EBC in 2007. We were introduced to him by three groups of friends who had each trekked with him before on the others’ recommendation. They were not wrong. Sappa ensured we were comfortable and from the moment we arrived in Nepal. Organising everything from transport to our hotel to making sure I’d all the gear needed for our trek. He even wanted to carry my pack! during the trek the high level of service continued. Sappa was knowledgeable and we felt confident in his ability at all times. He made the trip fun and was always making us laugh. I have absolutely no hesitation in recommending my friend Sappa. I’m happy to be contacted if anyone wanted further information Facebook http://facebook.com/peterdevenney
