Everest & Gokyo Lakes Circuit

Embark on a circular trek via the Gokyo Lakes, crossing the Cho La pass to Everest Base Camp

This circular Everest Base Camp trek explores the heart of the Sherpa homeland, from Namche Bazaar to the Gokyo Valley, crossing the glaciated Cho La pass and onto the classic route to Everest Base Camp used by the great climbing parties. Allowing ample time for acclimatisation, we can explore this high mountain wilderness, the quieter Gokyo Valley plus the main Everest trails. Our goal is Everest Base Camp on the Khumbu Glacier with the chance to climb Kala Pattar (18,192ft/5,545m) for fabulous close-up views of Everest.

Sustainability and Impact

As a certified B Corp, we’re on a mission to improve our social and environmental impact across all our adventures.

We do this through our innovative Thriving Nature, Thriving People plan.

This ‘nature positive’ approach is designed to help nature and communities thrive in harmony though practical solutions, such as reducing carbon and waste on our trips, supporting conservation projects through the Exodus Adventure Travels Foundation, and rewilding 100 square metres for every Exodus traveller.

Is this trip for you?

This trek is graded Activity Level 6 (Challenging & Tough) with 15 days of walking and full porterage throughout. You need only carry your daypack. For more information on our trip gradings please visit the Activity Level Guidelines page. If you have any queries about the difficulty of the trip please do not hesitate to contact us.  

Most of the walking is at relatively high altitude. The maximum altitude is 18,192ft (5,545m) with the average being 13,450ft (4,100m), please refer to the Altitude Warning within the Trip Notes. The itinerary is designed with built-in acclimatisation days to maximise the chance of successfully crossing the Cho La pass, reaching Base Camp and climbing Gokyo Ri and Kala Pattar. The reward is panoramic views spanning pristine glacial lakes, expansive glaciers and the highest mountains in the world.

Anyone attempting this trek should be confident in their physical fitness and ideally have previous experience of trekking at altitude.

This circuit is tougher than the classic Everest Base Camp trek as it involves a long, demanding crossing of the Cho La pass (17,780ft/5,420m). This entails a very steep ascent and descent on rocky trails, which can be icy; there is always ice and snow at the top as we cross a glacier. There are chains on the steep ascent up the Cho La.

Besides the pass, most of the walking is on well-established trails but there may be snow and ice at the highest points of the trek on any departure. Although daytime temperatures can be very pleasant, the nights will be cold. At Gokyo and around the Base Camp area it can be well below freezing, especially on the winter departures. In very bad conditions or after very heavy snowfall, Cho La may be impassable, in which case we take a lower route. The trail also crosses a few modern suspension bridges with mesh sides; anyone with a strong fear of heights or vertigo may find them difficult.

This trip includes domestic flights – please refer to the Transport section of the Trip Notes for information about flight safety in Nepal.

Walking hours stated within the itinerary are given as approximates only. Timings exclude lunch stops and will vary depending on the group’s pace.

Nepal flight safety

Many of our treks in Nepal use domestic flights to reach the trekking areas. The mountainous Nepalese terrain is subject to changeable weather, which makes flying conditions complex and challenging, and unfortunately there are significantly more incidents here than in other countries, including fatalities. The EU highlighted the poor safety record in Nepal in 2013 by including all Nepalese-registered airlines on the EU banned list, which prevents them from flying in EU airspace. While no Nepalese-registered airlines currently fly within the EU, the EU instigated this ban to highlight the risk of flying in Nepal to EU citizens. These airlines are unlikely to be members of any internationally recognised safety audit systems and the Civil Aviation Authority (CAA) of Nepal does not operate to the same standards as those of Western nations.

Flying within Nepal is therefore a known risk and we strongly encourage you to consider this carefully before booking. We suggest you refer to the following sources:

• The current travel advice for Nepal issued by the UK Foreign, Commonwealth and Development Office
• The Air Safety Network entry for Nepal

In response to concerns over this safety record, Exodus arranges for independent air-safety auditors to visit Nepal annually to assess the suitability of the available carriers. We then restrict our use to only those approved as part of this audit. In emergency situations, we will need to use helicopters, so we also have a list of approved helicopter carriers. Should concerns arise regarding the safety of an airline on our approved list, we remove the carrier from the list immediately, and it would only be reinstated once our air-safety auditors are confident the airline meets acceptable safety standards.

We appreciate you may have concerns about flying within Nepal, so we ask that you please consider all the information above when deciding to book this trip.

Internal flight delays

Adverse weather conditions at Lukla airport occasionally mean that flights to/from Kathmandu cannot operate. We include an additional day at the end of the itinerary to allow for this but please note that persistent bad weather may delay the start of your trek or your return to Kathmandu.

Should there be a lengthy delay at the start of a trip, we aim to provide a shortened Everest trek; however, if adverse weather conditions continue and the main objective of the trek becomes impossible to reach, an alternative trek to another region in Nepal will be offered. When fixed-wing planes are unable to fly, but helicopters to Lukla are available, clients may choose to travel by helicopter; in this event, the price per person will be approximately US$600-US$800, of which Exodus will cover half.

Should there be a significant delay at the end of your trek, we endeavour to get you on the first available fixed-wing flights to Kathmandu. If helicopters are able to fly, we will consider paying for these on a case-by-case basis to enable you to meet your international flights. In the case of persistent adverse weather, Exodus will rebook international flights for Flight Inclusive clients, but clients booking on a Land Only basis will be responsible for rebooking their onward travel and for any associated costs.

All flights to and from Lukla will no longer operate in/out of Kathmandu Airport (KTM), these flights have been transferred to operate in/out of Manthali Airport (RHP), which is in the Tamakoshi River Valley in Manthali, 82mi (132km) east of Kathmandu. The journey from Kathmandu to Manthali is a four-hour bus drive in the early morning and the return leg from Manthali to Kathmandu is usually five to six hours due to heavier traffic later in the day. The flight time between Manthali and Lukla is about 20 minutes.

It is necessary to depart your hotel in Kathmandu at approximately 3am by bus to ensure arriving in Manthali for 7am-7.30am in time for the flights to Lukla (between 8.30am-9am). Your Kathmandu hotel will provide a packed breakfast for the journey.

Following a review of all our trips we have categorised this trip as generally not suitable for persons of reduced mobility. However if you are a regular traveller on such trips, please contact customer services to discuss the trip and your personal condition.

Vaccinations and Health

Nepal

There are no required vaccinations. However, recommended vaccinations include tetanus, typhoid, hepatitis A, hepatitis B, cholera, Japanese encephalitis, rabies and tuberculosis. You will also need a yellow fever vaccination certificate if you’re arriving from a country with risk of yellow fever transmission or transiting for more than 12 hours through a country with risk of yellow fever transmission. Some travellers may also need proof of a polio vaccination. Please confirm with your doctor or travel clinic.

There is little to no risk of malaria in Nepal; therefore, antimalarial tablets are not usually advised although may be considered for certain high-risk groups. You may wish to consult your doctor or travel clinic for further advice.

Additionally, dengue fever and chikungunya are known risks in Nepal. Both are tropical viral diseases spread by daytime biting mosquitoes. There is currently no vaccine or prophylaxis available for either, and therefore the best form of prevention is to avoid being bitten. We recommend you take the usual precautions to avoid mosquito bites.

Most of our trips to Nepal go to high altitudes where there is a risk of being affected by Acute Mountain Sickness. Our itineraries are designed to enable everyone to acclimatise to these altitudes, but you should be aware that it is still possible for you to be affected. Please refer to the Altitude Warning within the Trip Notes for further advice on AMS.

When trekking at altitude, and particularly in cold weather, there is a higher chance of developing a cough (sometimes referred to here as the Khumbu cough) or cold symptoms. These symptoms could be a result of inhaling cold mountain air or dust (in the Everest region). You can mitigate against picking up coughs and colds by washing your hands with soap and water at available opportunities and using hand sanitiser. Also wear a buff over your neck and mouth when walking at altitude, particularly in colder weather, which will help limit cold, dry air entering your airways and keep your neck and chest warm.

Visa

Nepal

You can obtain your visa in advance or on arrival. The Immigration Department of Nepal has suspended visas on arrival for certain nationalities – please check if this applies to you with your nearest embassy or consulate.

Visa in advance

To get a visa in advance you can apply online at nepaliport.immigration.gov.np and collect it from your nearest Nepali embassy. Find more information at www.immigration.gov.np.

Visa on arrival

1. When you arrive at Tribhuvan International Airport in Kathmandu, there will be three lines. If you have already secured your visa, go straight to the Immigration line. If not:
   Fill in a tourist visa form at the electronic kiosks. After inserting your passport, the machine will automatically fill out an application form, take an electronic photograph of you and print a paper slip. If the machine won’t read your passport, complete the details manually using the touchscreen. We recommend taking a passport photo with you just in case.
   Top tip: This process can be completed through the online immigration portal (click ‘Visa On-Arrival’) within 14-days prior to arrival in Kathmandu, helping you to avoid lengthy queues at the kiosks when you come through immigration – ensure you print and bring the confirmation with you. If you have completed your visa on arrival form in advance, go directly to the visa fees counters with your printed confirmation and skip the kiosk queues.
2. Proceed to the visa fees collection counter and pay the visa fee (in cash, if possible). Make sure to keep the receipt. Card payments are not always possible, so paying in cash is easiest, most currencies are accepted but US dollars are preferred.
3. Go to the relevant immigration desk and present your tourist visa form, payment receipt and passport to obtain your 15-, 30- or 90-day visa stamp. Please check you have been given the correct visa duration.

Food & Drink

Breakfast is included throughout the trip.

In the teahouses, breakfast will be a choice of bread (a slice of toast, chapatti or Tibetan bread), a choice of egg (boiled, fried or omelette), and a choice between either muesli or porridge each day. Hot tea/coffee is also served. On specific days, there will not be a choice for breakfast and either a trekkers breakfast (egg, hash brown, baked beans and toast) or a pancake with jam/honey will be served – these options are not available in all teahouses and so we have only included them in locations where they can be guaranteed. You may also be able to supplement your included breakfast with additional items on the teahouse menu should you wish. Additional items that are not included in the set menu should be ordered and paid for separately.

Please note, some more remote teahouses/lodges are unable to provide an extensive menu due to irregular delivery schedules and during periods of bad weather or a high volume of trekkers, there may be a more limited menu choice. Also, the higher altitude the more expenses the menus and extras generally are.

Lunch will be taken at a teahouse en route – sometimes one of your guides will go ahead with the group’s order to make it more expedient. Dinner will be in the same teahouse that you sleep at (this is custom in Nepal as teahouses base their room rate on it).

Although most lodges have almost identical menus, they are reasonably extensive and offer a varied selection, ranging from traditional Nepalese dhal bhat to pizza and apple pie. Dhal bhat is the staple diet in Nepal and comes in many different forms but generally comprises curried lentils and meat or vegetables, some rice, and a pickle/chutney. Another popular snack is momos; a type of Nepalese dumpling, fried or steamed, filled with meat or vegetables.

Meat is available in the teahouses but we advise against eating it on trek. The meat has often been carried in the heat from lower altitudes for several days before reaching the lodges and can cause stomach upsets or illness. Germs can also be spread by handling dirty money – we recommend using hand sanitiser.

If you have a gluten-free diet, we strongly recommend you bring extra food and snacks with you to supplement the food on trek as there will be little variety available for you, particularly for breakfast. Even many of the soups are powdered and contain gluten. Gluten-free breakfast options will be limited to vegetable fried rice and a choice of egg, and on specific days only, a trekkers breakfast (without the toast/with an extra egg). Breakfast options for vegans will be limited to a choice of muesli/porridge with water each day, and on specific days only, a trekkers breakfast (without the egg) or vegetable fried rice. If you are lactose intolerant, the same will apply although you will also have a choice of egg each day.

If you buy imported food and drink on trek, you will spend more than the suggested amount.

Drinking water

Staying hydrated is important when undertaking any physical activity but particularly at altitude where it is generally recommended you drink at least 100floz to 135floz (3-4 litres) per day.

We strongly encourage you not to buy bottled water on trek as this contributes to the growing problem of plastic pollution in Nepal.

The teahouses sell boiled water for approximately 150-300 rupees (US$1.80-US$3.65) per litre (the price increases the higher you trek) which should not require treating. This is also perfect for a bedtime refill as it can double up as a hot-water bottle.

Alternatively, all teahouses provide free cold water. Although this should not be drunk untreated, we recommend you bring a reusable bottle/water bladder/Camelpak (ideally two) and use an effective form of water treatment. There are a wide range of products available including Steripens or purification tablets, which are the quickest and easiest options to use on trek – we recommend talking to an outdoor retailer for the latest advice as technologies are improving all the time. Make sure to check the product’s performance in cold/freezing conditions and consider battery life (lithium batteries are best in cold conditions).

Exodus has partnered with Water-to-Go, a filtration system that eliminates more than 99.99 percent of all microbiological contaminants from any non-saltwater source – visit Water-to-Go for more information. Exodus customers can claim 15 percent off their first order and, better still, 15 percent of the purchase value will be donated to the Exodus Travels Foundation. These bottles filter the water as you drink through the spout may not be the most efficient while on the go on a trek. Please note, if the water freezes it will clog up the filter. In this event, defrost before use by sitting the filter in lukewarm water for 10-15 minutes.

Weather

The main trekking season in Nepal is from mid-September to mid-May. We do not operate treks in Nepal outside these months as it is the rainy season. During the trekking season, conditions at most altitudes are generally comfortable for walking and rain or snow are occasional occurrences. Daytime temperatures will vary from 15C to 35C (59F to 95F) in the Kathmandu Valley to around 10C (50F) at 11,810ft (3,600m) and progressively lower the higher we go.

Within the trekking season, there are three further distinct seasons in the weather, each offering different advantages for trekking.

Post-monsoon/autumn (mid-September to November): This is the most popular trekking season in Nepal. Day temperatures in Kathmandu are generally above 20C (68F). On trek, temperatures will be lower although skies are usually clear and days should be sunny and mild with clear mountain views. However, at higher altitudes, the days can be cold and windy. Nights will be colder with temperatures dropping as low as -10C (14F) or lower in late November at the higher altitudes.

Winter (December to end of February): Despite the colder conditions, this is an ideal time to trek in Nepal. Skies are usually very clear, especially in December, and the mountain views are at their best. Nights will be very cold with temperatures down to -20C (-4F) but days are often pleasant and sunny. In Kathmandu, maximum daytime temperatures are 19C (66F).

Pre-monsoon/spring (March to May): Both day and night temperatures will be warmer in general but haze will often build up in the afternoons. It is very hot in the lowlands and temperatures rise to 30C (86F) in Kathmandu. Flowers bloom in this season and this is one of the reasons people chose to trek in spring.

Snow can be expected on any departure, usually at the higher altitudes. There will always be snow/ice on the top of the Cho La pass as it is a glacier.

Please remember that in any mountain area the weather is never wholly predictable and you should be prepared and equipped to deal with any differences in weather beyond the conditions described above.
