After awesome 40 minutes flight from Kathmandu to Tenzing-Hillary Airport at Lukla with mind blowing views along the flight you will land at tiny mountainous village draped by mighty peaks from all sides. We begin our walk from there to Phakding after some arrangements and meeting with the rest of the crew.
DAY 4: Phakding – Namche Bazaar
Few uphill and downhill accompanied by numerous crossing of Dudh Koshi River while being stared down at by the Mount Thamserku offers a great start to our journey. We cross several bridges to reach the entry gate of Sagarmatha National Park. The walk along the river bed leads us to Jorsale. After crossing Hillary suspension bridge, we climb a hill towards Namche Bazaar. Beautiful view of Kwangde Peak can be observed along the way. We rest at Chautara to further enjoy vistas of Kusum Kangaru, Lhotse, Mount Everest etc. Finally we reach primary hub of the entire Mountain Region and marketplace for the local inhabitants i.e. Namche Bazaar. We stay at Namche Bazaar for the night.
DAY 5: Acclimatization at Namche Bazaar.
We rest for the day at Namche to acclimatize ourselves as per the suggestion of health experts. The activities we do at Namche depends upon team discussion. We may take a day hike to Thame or visit Khunde or stroll around Namche Bazaar. Namche Bazaar fulfilling its criteria for being the hub of the region is equipped with ATMs, cyber café, bakery and great market. If we walk up to Khumjung we can get some view of Kongde and Thamserdu. There is a monastery hosting a Yeti scalp and Hillary School. We have sound sleep at Namche Bazaar.
DAY 6: Namche Bazaar – Dole
We make steep ascent up to Kyangjuma Village then cross the Mong La pass which houses an ancient Chorten stand in the middle. The top of the Mong La serves you with the panoramic vistas of mountains. Spotting pheasants, mountain goats and musk deer is not surprising along the way. After some more walking through the forests, waterfalls and bridges we arrive at Dole where we spend the night.
DAY 7: Dole – Machherma
The path is upwards in most of the region as we tread up to Lhabarma. We may find some summer settlements along the way as we remain mesmerized by awesome views of Cho Oyu, Kantega and Thamserku. Rumbling Dudh Koshi keeps us inspired while we walk uphill to Machherma. The first sighting of Yeti took in this very place which boasts of stream flowing down from Kyajo Ri and Phari Lapche through the village’s mid-point. We rest at Machherma for the night.
DAY 8: Machherma – Gokyo
Today the route passes through Chorten and reaches Pangka. Pangka is the tragic place where an avalanche killed 40 people around 20 years ago. From Pangka we make a descent to the river bank before resuming the uphill trek to the terminal moraine of the Ngozamba Glacier. As we walk further we reach the first lake known as Longpono (4690 meters). The next stop, serene blue sheet of water at second lake Taboche Tsho makes you feel that you are in heaven. A short walk from there and you will arrive at the third lake i.e. Dudh Pokhari while Cho Oyu mountains works as background picture.
DAY 9: Gokyo Valley
As suggested by our pool of trek experts we will rest today for the whole day however we will be engaged in some light activities. We will observe the fourth lake Thonak Tsho and fifth lake Ngozumba Tsho. Thonak is located about 3km away from Gokyo and little further from it we will be at Ngozumba. The summit of the hills lying at the edge of lakes is called Scoundrel’s Point which offers awe-inspiring vistas of Mount Everest, Lhotse, Nuptse and Makalu. To the north of Ngozumba lies Cho Oyu Base Camp and Ngazumpa Glacier. We return to Gokyo for the night.
DAY 10: Gokyo Ri – Thaknak
We trek towards the focal point of the trip i.e. Gokyo Ri. It is a steep climb which takes 3/4 hours to complete but the hard work is worth undertaking because once you reach to the top you will find yourself surrounded on all sided by the mightiest of the mighty mountains like Kusum Kangru, Everest, Pumori, Nuptse, Makalu, Lhotse etc. This image we assure you will remain in your memories till your last breath. We get back to Gokyo and walk to Thaknak for the night.
DAY 11: Thaknak – Cho La Pass – Dzongla
We have another difficult day for our trip as Cho La Pass is steep ascent and constitutes of glacier traverse on the eastern side which makes the trail slippery. Again Mother Nature compensates us for our dedication as we find Ama Dablam on south, Cholatse on the west, Lobuche on the east and Baruntse on north. We pass through some crevasses to reach Dzongla for the night.
DAY 12: Dzongla – Lobuche
Today we walk down from Dzongla to cross a bridge then pressing through grassy paths while relishing ourselves with beautiful view of Lobuche we finally reach Lobuche. Our trek will be little short today facilitating the relaxed observation of astounding location.
DAY 13: Lobuche – Gorak Shep – Everest Base Camp
We walk through Lateral moraine of the Khumbu Glacier and further small climb will take us to Thangma Riju which offers panoramic views of magnificent mountains. Further hiking leads us to Changri Glacier and we will be able to take the glimpse of Kala Patthar. Then we walk to Gorak Shep and bit more effort to Everest Base Camp where we treat our eyes with the serene beauty of Nuptse, Khumbuste and Pumori. The irony is that Everest still remains suspense. We return to Gorak Shep for the night.
DAY 14: Gorak Shep – Kala Patthar – Pheriche
At the very first hour when the chilly cold winds seem to pierce our heart we ascend to Kala Patthar while aforementioned mountains stare upon us. After we reach the top of Kala Patthar we forget all our pains as our eyes stay focused to capture every detail of such a unique beauty of mountains. The storage of your cameras may not be enough to take in all the Himalayan panorama of Lingtren, Khumbutse, Changtse, Nuptse, Everest etc.
DAY 15: Pheriche – Pangboche – Tengboche – Namche Bazaar
Relatively today’s trek is very easy as we walk down the same route that we ascended all along. We get to know much more about the Sherpa community as we walk along their small villages like Pheriche, Orsho etc. Then we pass through Pangboche and Tengboche praising the surrounding full of rhododendrons. If we are lucky we may be received by some wilderness like snow leopard, colorful pheasants etc. Finally we reach Namche Bazaar safe and sound. You can have a warm bath and sound sleep that you deserve the most.
DAY 16: Namche Bazaar – Lukla
After crossing several suspension bridge upon roaring Dudh Koshi river and enjoying the typical mountainous life further enhanced by Buddhist culture we ultimately arrive at Lukla. We sleep at Lukla waiting for our flight back the next day.

Weather in Nepal Chola Pass Trek
Normally weather can be divided into four different quarters through out the year, we would love to provide some more information details regarding weather condition and others which makes you easier to decide what shorts of clothing, equipment are necessary as well as wise to carry.
Spring – March to May
Second best season for Trekking in Nepal is from March to May, which is considered as spring season in Nepal. Just before rain hits trekking trail in Nepal during March to May Nepal used to be bloomed with rhododendron forest with clear blue sky. Especially base camps of eight thousanders used to get lots of crowd especially for expedition purpose, as weather is clear most of the time with suitable temperature for expedition. Average city temperature during March to May ranges as
Average Daily Temperature – Ranges from 24 to 28 (Degree Celsius)
Average Night Temperature – Ranges from 8 to 16 (Degree Celsius)
Rainy – June to August
Normally high mountain flights in Nepal used to get canceled during these periods because of poor visibility and rainfall. Heavy rainfall in lower alpine as well as frequent snowfall in high alpine region trekking is almost stopped during this trek. As chances are high for rock fall in alpine passes and closing of teahouses make more difficult too for treks. However city tour are still feasible with help of vehicles and for more adventure rafting as most to do list for extreme adventure.
Average Daily Temperature – Ranges from 21 to 24 (Degree Celsius)
Average Night Temperature – Ranges from 14 to 18 (Degree Celsius)
Winter – December to February
Extreme snowfall and low temperature is totally unfavorable for high alpine trek as most of the trails are blocked by heavy snow making almost impassable. Another major obstacles is closing of teahouses as during such periods of year most of the teahouses on start and end of passes. So either way you need to walk two days trail is same days but it is almost impossible so simple trekking in Ghorepani Poonhill, Nagarkot Chisapani are more feasible and attracts lot of people. City area and sightseeing are ok with freezing cold especially during morning and late night. Views are ok everyday with clear sky and snowy peak far beneath horizon. Do not forget to get winter clothes before you departure for Trip in Nepal.
Average Daily Temperature – Ranges from 19 to 20 (Degree Celsius)
Average Night Temperature – Ranges from 3 to 5 (Degree Celsius)
Fall – September to November
Right after monsoon is over sky is greeted by light blue color, one of the most favorable weather periods. Trekking trail are full of trekkers, hotel are sometimes overbooked everybody are busy with tour trekking stuffs, hard to get airlines ticket as well as bus ticket to major cities. Warm days snow free elevation even up to base camps. Be prepared in advance for all necessary booking and reservation stuffs as it is peak season all quality things are either booked in advance or might be busy. One of the best weather periods in Himalayas with average temperature as below
Average Daily Temperature – Ranges from 19 to 27 (Degree Celsius)
Average Night Temperature – Ranges from 8 to 17 (Degree Celsius)
As per arrival
As per arrival representative of NEST ADVENTURE will greet you in airport’s arrival terminal and shift to hotel in Thamel for first overnight stay in Nepal. For this you need to finish paper work inside arrival terminal in order to get Nepal Entry Visa, which is always arrival visa. So next day will be followed by sightseeing in Kathmandu and preparation of trek, introduction with crew member of trek and short pre-briefing of trek and continue trek starting from 3rd day of arrival in Nepal.
As per booked package either deluxe or budget we will arrange the hotel in Kathmandu accordingly on 3 star / 4 star of budget hotels, as well as accordingly in mountain too on twin sharing basis. As per available and booked we will provide attach bathroom and common bathroom on mountain. While sharing the room with fellow trekkers we will try to arrange for same gender and age group and if someone is looking for single supplement then let us know we will arrange accordingly and let you know the extra charge of single supplement. As well as sometime in mountain during peak season time hotel owner especially in high alpine area refuse to provide single supplement just for shake of business mostly because lack of plenty of rooms and monopoly to, so in such case we might need to adjust.
Meals and drinking water
Regarding the case of meals during city we provide accommodation on bed & breakfast basis so in Kathmandu we offer breakfast where lunch and dinner will be on your own as per your choice preference and selection of restaurant. In case of mountain area while trekking we offer three meals a day i.e. breakfast, lunch and dinner from free selection over menu as per available in lodges and tea houses in trekking trail. So normally in such trekking days you can consult with your guide regarding the specialty of dishes so that he can assure for the best-valued dishes. Wide range of food are available ranging from veg item to non-veg and other energetic stuffs like cheese, egg etc.
Regarding the case of drinking water normally bottled mineral water as available for purchase of very expensive almost 20 times expensive in last belt of Everest as bottle of mineral water sometimes cost Rs. 380-400 /- so it is better to carry water purification stuffs with you which can be utilized on purifying tap water as there are enough tap water in trekking area as well as hotels offer cold tap water free of cost.
Out of one visa year tourist visa can be obtained of maximum 90 days, which you can directly get as per arrival in international airport or can apply from your home country too but as per arrival will be fine too. It is recommend carrying accurate USD and don’t forget to bring two copies of passport size picture. Extension of visa from middle of stay in also possible for this process of visa extension all you need to do is fulfill form from website of immigration and submit it there with original passport copy. Multiple entry visas will be cheaper in case of money you can consult there directly.
International flight to Nepal
Nepal is easily accessible from entire word via flight, as we don’t deal with international flight ticket you can consult some other flight booking agencies for detail of cost, transit and other details. For your information no airport tax is applicable for international flight where as Nepali Rs. 200 is applicable for domestic flights which is equal to US $ 2 on basis of exchange rate of 1 USD equals Rs. 100 but sometime might get different by 0.10 / 0.20 USD on basis of exchange rate. Most of time especially in rainy season domestic flight gets canceled because of bad weather however it does not affect international schedules most of the time.
Currency and foreign exchange rate
In Nepal both coin as well as paper notes are in used however coin are of low value only. But regarding the case of paper note for day-to-day used are 5, 10, 20, 50, 100, 500 & 1000. Do not worry about damaged paper note as it there exist clear number of currency on both side it is applicable, one can do anything with paper notes like squeezing, writing over it etc.
Since Nepal has fixed exchange rate with Indian currency exchange rate doe directly depend on value on Indian currency, now a day exchange rate of USD is 1 USD equals Rs. 95 in approximate, can check everyday over internet for current exchange rate. And for information about currency that are majorly accepted in Nepal are Indian currency, Chinese, Japanese, Korean, USD, AUD, CAD, GBP, Euro, Swiss Frank, Riyal etc.
Normally while walking in lower elevation steadily, taking enough acclimatization days we can avoid chance of acute mountain sickness however we cannot totally avoid mountain sickness instead we can lower the chance of occurrence by following some rules and paying lot attention for personal hygiene. Since the remote mountain area are not facilitated by motor roads and modern hospital so incase of strong mountain sickened one and only option is to descend as down as possible which is feasible with use of helicopters only. Such kind of expenses in high elevation area extremely off the edge and cannot be offered easily as sometime cost more than one million rupees, so it is better to have a personal health insurance. As we do not deal with such kind of health insurance but we do have good enough information about insurance providing company as some deal very quickly promptly for case where as some try to avoid and create some unnecessary delays in evacuation process. So as per need of information we will let you know some good provider from your region so that it will be easy in worse case in mountains.
High altitude sickness
Often known as acute mountain sickness are most dangerous things and any one can be victim of AMS apart from their physical strength. There is no such specific medicine for AMS so one needs to be careful from beginning. Major Symptom of AMS is dizziness, vomiting, nausea, and loss of appetite, weakness and insomnia so in order to rid of AMS major thing is to drink plenty of water and enough acclimatization in high alpine area. Although our crew leader will have adequate first aid medicine and kit sometimes one might need to cancel the trip and descend down in case of increasing symptom of AMS and in case of emergency situation clients will be airlifted immediately for further treatment in hospital at Kathmandu.
