The Everest Base Camp Trek is best undertaken during spring and autumn, when weather conditions are generally more favourable for trekking, mountain views and high-altitude travel. SPRING — MARCH TO MAY Spring offers milder daytime temperatures, longer daylight hours and spectacular views of the Himalayan landscape. Lower sections of the trail come alive with blooming rhododendrons, while Mount Everest and the surrounding peaks create a magnificent backdrop. This is also a popular season for Everest climbing expeditions. AUTUMN — SEPTEMBER TO NOVEMBER Autumn is one of the best seasons for the Everest Base Camp Trek. Following the monsoon, the skies generally become clearer, offering excellent visibility of Mount Everest, Ama Dablam, Lhotse and other Himalayan giants. October and November are particularly popular for their crisp mountain air and panoramic views. WINTER — DECEMBER TO FEBRUARY Winter offers quieter trails and potentially clear mountain views, but temperatures can fall well below freezing, particularly at higher elevations. Snowfall, icy trails and harsh weather may affect the trekking experience and accessibility of some sections. Winter departures require suitable equipment and careful planning. ​​ALTITUDE & ACCLIMATIZATION The Everest Base Camp Trek begins at Lukla, approximately 2,860 m above sea level, and follows the Dudh Koshi valley through Phakding and Namche Bazaar before continuing towards Tengboche, Dingboche, Lobuche and Gorak Shep. The trek reaches Everest Base Camp at approximately 5,364 m (17,598 ft). Many itineraries also include an early-morning ascent of Kala Patthar, approximately 5,545 m (18,192 ft), offering exceptional views of Mount Everest and the surrounding Himalayan peaks. At these elevations, the reduced availability of oxygen places additional demands on the body. Trekkers may experience cold temperatures, strong winds, fatigue, disturbed sleep and altitude-related symptoms. Our itinerary incorporates planned acclimatization opportunities and a gradual ascent to help trekkers adapt to increasing elevation. Important Acclimatization Guidelines Maintain a steady, comfortable walking pace and avoid unnecessary exertion. Follow the planned itinerary, including designated acclimatization days. Drink fluids regularly and eat sufficient, nourishing meals. Allow adequate time for rest and recovery. Inform your trekking leader immediately if you develop symptoms such as a persistent headache, nausea, dizziness or unusual fatigue. Never continue ascending when experiencing symptoms of altitude sickness without appropriate assessment. Descend promptly and seek medical assistance if serious altitude-related symptoms develop. Acclimatization is essential, but it cannot eliminate the risk of altitude sickness. Good physical fitness does not guarantee protection against altitude-related illness. The itinerary may need to change in response to a trekker's condition, weather or other safety considerations. PHYSICAL PREPARATION Begin preparing several weeks to a few months before your departure, depending on your current fitness level and trekking experience. The Everest Base Camp Trek involves consecutive days of walking, sustained uphill sections, steep descents and extended periods at high altitude. Building endurance gradually will help you manage the physical demands of the journey. Recommended Training Regular walking and hiking: Build up your walking duration and distance progressively. Stair climbing: Improve leg strength and endurance for sustained ascents. Cardiovascular exercise: Include activities such as brisk walking, cycling or swimming. Strength training: Focus on the legs, hips, core and overall stability. Backpack training: Practise walking with a lightly loaded backpack similar to the one you will carry on the trek. Recovery: Allow adequate rest between training sessions to reduce the risk of injury. The goal is endurance, not speed. Being able to walk comfortably for several hours on consecutive days is more useful than completing a short distance at a fast pace. A well-prepared trekker is better equipped to enjoy the journey, manage fatigue and maintain a consistent pace throughout the expedition. WEATHER & TEMPERATURE Mountain weather in the Everest region can change quickly. Conditions vary considerably between lower valleys, exposed ridges and high-altitude locations such as Gorak Shep and Everest Base Camp. Depending on the season and elevation, you may encounter: Bright sunshine and strong ultraviolet radiation Rain and wet trails at lower elevations Fog and cloud cover that reduce visibility Cold winds and exposed mountain conditions Frost and freezing overnight temperatures Snowfall and icy trail sections Significant temperature drops after sunset Delays caused by adverse weather and flight conditions Temperatures at higher elevations can fall well below freezing, especially at night and during early-morning excursions to Kala Patthar. Essential Clothing & Equipment A suitable layering system is essential for managing changing temperatures throughout the trek. We recommend carrying: Moisture-wicking base layers Warm insulating layers, including fleece or down A waterproof and windproof outer jacket and trousers Warm trekking trousers Insulated gloves and warm headwear A sun hat and UV-protective sunglasses Comfortable, well-broken-in trekking boots A warm sleeping bag suitable for the expected conditions, if not supplied as part of your package Your final packing list should be based on the season, the itinerary and the equipment included in your trekking package. ​ ACCOMMODATION The Everest Base Camp Trek follows an established mountain route with accommodation primarily in local teahouses and trekking lodges. These provide a practical and welcoming place to rest, eat and recover after each day's walk. Kathmandu Accommodation in Kathmandu may be arranged before and after the trek, depending on your selected package. Options can be discussed according to your itinerary, preferred comfort level and budget. Along the Trekking Route Lukla and Phakding: Teahouses and lodges offering basic to comfortable facilities. Namche Bazaar: A larger mountain settlement with a range of lodges, guesthouses and dining facilities. Tengboche, Dingboche and Lobuche: Mountain teahouses with increasingly basic facilities as the trail gains altitude. Gorak Shep: Basic high-altitude lodge accommodation near the final approach to Everest Base Camp. Accommodation Facilities Rooms are generally arranged on a twin-sharing basis, subject to availability. Toilets and bathrooms may be shared, particularly at higher elevations. Hot showers and charging facilities may be available at additional cost. Heating is generally limited, and bedrooms can become very cold at night. Facilities become more basic and availability more limited at higher elevations. Accommodation standards vary by location, season and lodge availability. Private rooms cannot always be guaranteed during busy trekking periods. The experience reflects the character of the Everest region, where warm hospitality, local mountain culture and practical teahouse facilities form an integral part of the journey. ​ FOOD & MEALS Meals during the Everest Base Camp Trek are generally served at the teahouses and lodges along the route. The menu typically combines traditional Nepali dishes with familiar Indian and international options. The availability of particular dishes varies by location, season and lodge. As you gain altitude, menus may become simpler and food prices generally increase because supplies must be transported into the mountains. ​ Our Approach to Trekking Meals At The Great Hikes, we encourage trekkers to eat regularly, stay hydrated and choose nourishing meals that support the physical demands of high-altitude walking. Dal bhat, a traditional Nepali meal of rice, lentils and accompaniments, is a popular choice among trekkers because it provides a substantial source of energy. Vegetarian options are widely available, although the variety of fresh produce and other ingredients may decrease at higher elevations. Please inform us in advance about any dietary requirements or food allergies so that we can discuss the available arrangements. Meal inclusions depend on the selected trekking package. Your final itinerary and booking confirmation will specify which meals are included and which are payable directly at the teahouses. ​ PERMITS & DOCUMENTS REQUIRED The Everest Base Camp Trek takes place in the Khumbu region of Nepal, following established trails through the Sagarmatha National Park area. For the standard Everest Base Camp route via Lukla, trekkers generally require the following two permits: Sagarmatha National Park Entry Permit Khumbu Pasang Lhamu Rural Municipality entry permit Permit requirements, fees and procedures may change. The Great Hikes will confirm the applicable requirements for your departure before the trek. ​ FOR INDIAN NATIONALS Indian trekkers should carry: A valid Indian passport or another identity document accepted for the relevant travel and entry procedures. Appropriate identification for flights and other transport arrangements. Passport-size photographs, if required for the applicable permit procedures. Copies of relevant travel documents. Any additional documentation requested by the trekking operator or issuing authorities. Indian citizens do not generally require a Nepal tourist visa, but accepted identification requirements can differ depending on the mode of travel and the service provider. Confirm the appropriate documents before departure, especially if travelling by air. FOR OTHER INTERNATIONAL NATIONALS International trekkers should carry: A valid passport. A valid Nepal visa, where required for their nationality. Copies of passport identification pages and visa documentation, where applicable.

The Everest Base Camp Trek takes you deep into the high Himalayas, where altitude, weather and trail conditions can change quickly. The combination of prolonged walking, cold temperatures and reduced oxygen availability requires careful preparation and responsible decision-making. Our trekking team follows a considered approach to the journey, with appropriate pacing, planned acclimatization opportunities and attention to the well-being of participants. Our Safety Priorities Gradual Ascent: Following an itinerary designed to allow time for altitude adaptation. Experienced Trekking Leadership: Guidance from the designated trekking leader throughout the journey. Regular Communication: Encouraging trekkers to report symptoms, injuries or concerns promptly. Weather Awareness: Adjusting plans when conditions affect the safety or feasibility of the route. Responsible Decision-Making: Modifying the itinerary or arranging descent when necessary.
