Everest Base Camp itinerary: 12 trekking days plus flight buffers

How many days to allow

Allow about 12–14 days for the Lukla-to-Base-Camp return trek, then add Kathmandu arrival, the flight out of Lukla and disruption time separately. The 12-day walking sequence below includes two nights each at Namche and Dingboche; those acclimatisation days are part of the trek, not spare days to spend on a delayed flight.

For an initial calendar, reserve roughly 16–18 days in Nepal: arrival and preparation, the trek, a planned return-flight day and at least a couple of uncommitted days before your international departure. This is an editorial planning allowance, not a promise that two buffer days cover every cancellation. A longer approach, extra rest or a route change needs more time.

How to read this route

This is an editorial outline of the established south-side route through Tengboche and Dingboche. Nepal Tourism Board describes those villages and repeated acclimatisation stops; the cited Exodus programme provides a comparable 12-day walking schedule, although it uses Kyanjuma after its Namche-area acclimatisation walk rather than a second Namche night.

Sleeping elevations below are approximate, rounded from that programme’s lodge elevations; a village or lodge can be listed at a different height elsewhere. They are not daily ascent limits. The Namche approach and Dingboche-to-Lobuche stage involve substantial sleeping-height gains. CDC warns that even standard Everest schedules can exceed some travellers’ ability to acclimatise. More days may be needed.

Day 1: Lukla to Phakding

After the flight to Lukla, walk down the Dudh Koshi valley to Phakding. Overnight: Phakding, approximately 2,650 m. Keep the arrival flight and the first walk as separate items in your booking: a late arrival does not guarantee that the planned walking stage remains practical. Lukla flights may use Kathmandu or Manthali/Ramechhap; use the airport on your actual ticket.

Day 2: Phakding to Namche Bazaar

Continue through Monjo and the Sagarmatha National Park entrance area, then climb towards Namche. Overnight: Namche Bazaar, approximately 3,440 m. This is a substantial climb from Phakding, not a gentle continuation at the same elevation. Keep passport and permit records accessible for entry checks.

Day 3: acclimatisation day at Namche

Keep the same sleeping base. Overnight: Namche Bazaar, approximately 3,440 m. Depending on conditions and how you feel, a local walk may take in the Syangboche or Khumjung direction before returning to Namche. An acclimatisation day does not mean a compulsory high viewpoint hike; avoid treating a side trip as another target that must be completed.

Day 4: Namche to Tengboche

Follow the main trail towards the Imja valley and climb to Tengboche. Overnight: Tengboche, approximately 3,870 m. This is the monastery-village route. Packages using Phortse, Deboche or Kyanjuma have different stages and sleeping stops; compare the actual villages rather than assuming all Base Camp itineraries match.

Day 5: Tengboche to Dingboche

Continue through the Pangboche area and into the Imja valley. Overnight: Dingboche, approximately 4,350 m. Some programmes use Pheriche instead; that is a different overnight base, not an interchangeable spelling. Identify which village your accommodation and following day’s walk use.

Day 6: acclimatisation day at Dingboche

Stay a second night at Dingboche, approximately 4,350 m. Leave this day in the plan rather than using it to catch up with a delayed arrival. A short local walk and a longer excursion towards Chhukung are different commitments; the itinerary need not require the longer option. How you feel and the current conditions should take precedence over a scheduled viewpoint.

Day 7: Dingboche to Lobuche

Continue towards the Khumbu glacier and Lobuche. Overnight: Lobuche, approximately 4,930 m. This is another significant increase in sleeping elevation. Do not read the existence of this standard stage as evidence that it suits every trekker; the plan must remain changeable if symptoms develop.

Day 8: Lobuche to Gorak Shep and Base Camp

Walk to Gorak Shep, leave overnight luggage at the lodge, and continue to the Base Camp area only if conditions and your condition allow. Return to sleep at Gorak Shep, approximately 5,180 m. Base Camp is a visit, not the overnight lodge. The out-and-back section adds a long high-altitude walk over rough ground; reaching Gorak Shep is not a commitment to continue regardless of symptoms.

Day 9: optional Kala Patthar, then descend to Pheriche

Kala Patthar is a separate viewpoint above Gorak Shep, not another name for Base Camp. If included and appropriate on the day, visit before descending towards Pheriche. Overnight: Pheriche, approximately 4,240 m. Omit the viewpoint when weather, fatigue or symptoms make it unsuitable; descent is more important than ticking off both high points.

Day 10: Pheriche to Kyanjuma

Retrace the valley route towards the Namche area. Overnight: Kyanjuma, approximately 3,600 m. This return plan splits the descent over several days rather than assuming that one very long walk will recover time lost earlier.

Day 11: Kyanjuma through Namche to Monjo

Descend through Namche and continue to Monjo. Overnight: Monjo, approximately 2,850 m. Keep your entry records until you have finished the route; the descent still passes through the park’s access corridor.

Day 12: Monjo to Lukla

Walk back through the lower valley to Lukla. Overnight: Lukla, approximately 2,800 m. The trek finishes here; a flight back to Manthali or Kathmandu belongs on the following day’s transport plan, not inside an assumed same-day international connection.

Where extra days belong

Extra time can mean an additional lower-valley night, another night at an existing sleeping base or a less compressed return. Those choices change the route, so ask for a revised village-by-village plan rather than a headline “14-day trek”. Compare like with like: some sellers count Kathmandu hotels and transfers in the advertised duration, while others count only trail days.

Keep weather contingency outside the protected acclimatisation days. If an inbound flight delay consumes your margin, shorten the objective or extend the trip rather than automatically deleting Namche or Dingboche time. A helicopter return changes transport and cost; it does not undo the altitude exposure on the ascent.

When the schedule must stop

CDC advises gradual ascent and warns that fitness does not protect against altitude illness. Do not ascend to a higher sleeping altitude with symptoms of altitude illness. Tell your guide or companions promptly about headache with nausea, dizziness or unusual fatigue after ascent. If symptoms worsen at the same altitude, descend and seek medical help. Confusion, difficulty walking normally or breathlessness at rest call for urgent help and descent; do not continue towards Base Camp.
