As you explore this biodiverse region, you will also experience the vibrant Himalayan culture through the annual Buddhist Festival of Dumji within Sherpa communities.

First and foremost, please do not hesitate to reach out to us if you have any questions about your gear, training, inoculations, travel, or trekking logistics. My mobile phone number is +1-202-255-1191 and my email address is rsilber@imt-nepal.com.

We are excited you have chosen International Mountain Trekking to experience the spectacular Khumbu region located in the Sagarmatha National Park in Nepal. On an IMT trek, you will have the opportunity to visit Sherpa communities, enjoy traditional meals with Sherpa families, visit historic Buddhist monasteries and engage with the latest scientific discoveries in the region in a way not offered by other trekking companies.

The information here will address the details of the trek, including the safety and COVID-19 protocol during your time in Nepal. We have strong connections with Nepal’s Embassy here in Washington, and we are in regular contact with them to have the latest details on conditions in and traveling to Nepal.

1) Pre-Trip Preparation and Travel

NEPAL ENTRY PROTOCOL: Nepal has returned to its pre-Covid policy of issuing tourist visas at Kathmandu’s Tribhuvan Airport. Therefore, you will obtain your 30-day tourist visa as you make your way through customs at Tribhuvan Airport. Here are the steps you will take upon entry to the airport:

You will first enter a line to have your passport checked.
Upon exiting this line, you will begin the process of getting your 30-day tourist visa. After exiting the first line, go to the right side of the immigration room to fill out a form for a 30-day tourist visa on one of several visa kiosk machines. The machines are not connected to a printer, so once you have completed the form, use your phone to take a photo of your completed application. You are staying at the Kathmandu Guest House Saat Ghumti Marg 16, Kathmandu 44600, Nepal Phone: +977 1-4700800
When the form is completed, go to the payment counter on the opposite side of the entrance hall. Upon paying $50 dollars , you will receive a receipt for your visa payment. Present that receipt with your passport and boarding pass to the immigration booths at the front of the room and you will pass through immigration control.
Upon passing immigration, go down one level to the baggage claim room. Grab a cart, collect your baggage at the baggage claim area and head down the corridor to the elevators. Take the elevator to ground level. You will be greeted for pickup outside of the airport’s main doors. Look for the IMT Banner or someone holding a sign with your name. Your escort will be among the line of other individuals waiting to greet arrivals. Namaste! Welcome to Nepal!

BAGGAGE: We recommend you use your daypack as a carry-on bag and that you check one rolling suitcase. When you arrive at the hotel, we will provide you with your own IMT duffel which you will use on the trek and is yours to take home. Please bring a few items of clothing in your carry-on day pack in the event your larger bag is delayed. Don’t forget your passport, cash and the medications you require during your travel. Please take a photograph of your passport with and store it in your phone to have a record of it in the event of loss. Please check your luggage from your departing airport all the way through to Kathmandu. We recommend the use of TSA-approved locks to secure your luggage so that they can be opened, if necessary, by airport security.

EXTRA MONEY: How much additional cash to bring is an individual decision. We suggest you have at least $800 to spend for gifts, tips for your guides and porters and any additional meals outside of the itinerary. In Kathmandu you can use your credit card and a debit card to obtain Nepali rupees. It is difficult to change money once the trek starts.

IMT’s TIP POLICY: We will collect a tip pool in U.S. currency and ask IMT’s clients to each contribute $300. We will collect this tip pool in Kathmandu and distribute it at the conclusion of the trip as a thank you gift to the dedicated guides and porters who you will get to know throughout the trek. You may also provide an additional tip to your guides, porters, drivers and hotel personnel if you so choose.

TRAVEL AND MEDICAL EVACUATION INSURANCE: IMT requires you to insure yourself if you experience a medical emergency during the trek. While optional, we also strongly recommend you purchase Trip Cancellation, Interruptions, and Medical Insurance option, so that you are covered if you must cancel your trip, cut it short, or require medical attention while traveling. Your current health insurance may not cover your health care needs while travelling internationally.

We encourage you to contact the Travel Insurance Center +1-866-979-6753, ext. 3648 and ask for Mark Reineke whom I have found to be responsive, thorough, and extremely professional. As an insurance broker, the Travel Insurance Center represent 23 different companies, and they offer a wide range of options to meet your needs. Let them know you are an IMT client as they are familiar with our insurance requirements.

IMMUNIZATION CHECKLIST: Please consult your physician or check the Center for Disease Control Website at www.cdc.gov. Consistent with the current CDC guidelines, you should ask you doctor whether you require the following inoculations:

During the approach to Everest Base Camp, you will be exposed to higher rates of UV light and glare from ice sheets. Good eyewear is important, therefore, to both protect your eyes and to enhance your visual experience of the Khumbu. There are several different brands for you to consider.

We will update you if there are any changes in protocols for arrival. Remember to carry a ballpoint pen and some cash. After collecting your luggage, we will find you when you emerge outside. Please look for someone holding a sign with your name on it, or our International Mountain Trekking banner!

KATHMANDU HOTEL: You will be staying at the Kathmandu Guest House. This is a beautiful, historic, and perfectly situated hotel in the Thamel neighborhood of Kathmandu. Breakfast is included. You are responsible for all incidental charges to your room, including other meals, beverages, phone calls, and the like, and must clear these charges before we leave the hotel to start our trek.

PREPARING YOUR GEAR FOR THE TREK: While on the trek, you will leave your extra clothing and belongings in your rolling suitcase at the hotel in Kathmandu, including your street/travel items that will not be needed until you return to Kathmandu. You will transfer your trekking clothes and gear to the IMT-provided duffle which you will use on the trek. The maximum weight allowed on the helicopter is 15 kg (33 pounds) for your trekking duffle bag and 5 kg (11 pounds) for your trekking backpack. We will meet with each of you at the hotel to make sure you have all the right clothing and gear and to make sure you are not bringing unnecessary items and we will weigh your packed duffle!

PASSPORT SECURITY AND TRAVEL: We recommend you carry a photocopy of your passport on the trek (and take a photo with your phone so you have a backup). Please make sure you have the contact information for your travel agent or airline in case you need to email or call to make any changes. You may choose to leave your passport with your luggage at the Kathmandu Guest House.

FIXED-WING, GROUND AND HELICOPTER TRAVEL: We are traveling from Kathmandu to the Khumbu either by fixed-wing aircraft or by private Toyota Land Cruiser. Delays due to weather and/or road conditions may occur. At the conclusion of the trek, depending on your specific trek’s itinerary, you will return to Kathmandu by private helicopter or aircraft from Lukla.

IMT will cover the cost of your room for that last night or nights and a celebratory dinner. When you are ready to depart the hotel for the airport, please let us and/or the hotel staff to arrange transportation for you. Hold onto a few hundred rupees for the airport so you can buy a drink in the departure lounge and for tips for the baggage porters at the airport.

3) Trekking Logistics and Information

ACCLIMATIZATION AND HEALTH: We anticipate that you will not have difficulty with acclimatization. We have an itinerary and proven schedule which will enable you to acclimatize successfully. Based on peer-reviewed studies, we recommend 600 mg Ibuprofen prophylactically every 6 hours and staying well hydrated as a good overall strategy for handling the higher elevation. If you regularly drink coffee, stay on this routine. On the trek, you can also take Diamox (acetazolamide) if you desire, but we do not generally recommend it unless you are symptomatic for Acute Mountain Sickness (AMS). Current protocol is 125mg in the morning and 125 mg in the evening, starting when you begin to experience symptoms. Taking the smallest possible dose is best to avoid potential side effects, such as dehydration and tingling in your extremities.

Personal hygiene is important, and we recommend that before meals, you wash your hands with soap and water followed by antibacterial hand sanitizer. We also recommend bringing wet wipes and body wipes which will be used in lieu of showers on parts of the trek. It would not be unusual for you to get a cold or some travelers’ diarrhea at some point on the trek. The combination of travel in a developing country along with new foods, other trekkers, mountain lodges etc. will increase the risk of you contracting a minor illness. Should this occur, the likelihood is that you will recover fully within a few days without having to take medications. Current protocol for persistent diarrhea (≥3x days) is to start taking Cipro, but if there is no improvement after 24 hours, then can start on Zithromycin (Z-Pak). The Z-Pak also works well for bronchial ailments, so make sure you have a course or two of Zithromycin.

FOOD & DRINKING WATER: All meals on the trek are provided. You should bring sufficient additional snack foods and energy bars that you know you will enjoy eating for the duration of the trek. You should also consider supplementing your fluid intake with one of the many energy and endurance powders, such as those available from Hammer Nutrition. There are small grocery stores nearby the Kathmandu Guest House that sell an array of snack foods. On the trek, bottled water is available for purchase, or you can use water purification tablets or other purification methods. Using water purification tablets, while discretionary, helps to reduce the amount of plastic bottles in the Khumbu.

MEDICAL SUPPORT: In case of any severe issues, we will call in a helicopter for evacuation to Kathmandu. It is important that you have your rescue insurance and personal health insurance information with you. There is also a small hospital in Lukla.

POWER AND INTERNET: All the tea-house lodges where we are staying now have solar power available for charging your phone (normally at a rate of a couple hundred rupees/hour). Internet scratch cards are available in Namche Bazaar which you can use for wi-fi access with your smart phone. You may want to bring a small solar power charger.

For those interested in adding an additional level of challenge and excitement, take advantage of your acclimatization and set your sights on Lobuche Peak (20,075’). Led by our licensed and experienced high-altitude Sherpa guides, IMT’s Lobuche climb provides you with the ideal objective of climbing a Himalayan peak – all within the itinerary of our mushroom trek to Everest Base Camp. After reaching Everest Base Camp, our Lobuche team turns off the main trekking route and heads over to Lobuche base camp. Here, prior to your climb, you will receive mountaineering skills and training on the use of crampons, ice axe and ascending on fixed ropes. Climbing Lobuche Peak is an excellent opportunity for new or veteran climbers in good shape to expand their alpine experience, or for the first time, to summit a worthy Himalayan mountain. Lobuche is a terrific challenge with the fun and excitement of tackling stretches on fixed ropes of moderately steep glacier terrain toward the summit. There you will have incredible views of Everest, Cho Oyu, Nuptse, Lhotse, Makalu and mountain peaks across the region. If you already have your own mountaineering equipment, bring it along. IMT can also arrange to supply or rent everything you’ll need for a safe and successful climb. Please review IMT’s equipment list for what you’ll need to bring or rent in country.

Join a team of mycologists, mountaineers, journalists, and adventurers as they trek high into the Himalayas on a mushroom foraging expedition. Led by renowned Nepali mycologist Dr. Shiva Devkota, the group explores the remote mountains and forests of the Sagarmatha (Everest) National Park of Nepal, searching for rare and undiscovered mushroom species. Along the journey they connect with local villagers, experience Sherpa culture, witness the staggering natural beauty of Nepal, and have their spirits transformed through poignant moments of joy and sorrow.
