To get near Everest, you must either walk for a week long or fly to Lukla, a remote Mountain Airstrip where flights are notoriously unreliable. The Everest Region or Solu Khumbu Region is the Second-most popular Trekking in Nepal. It would probably be the most popular destination for the trekkers, but it is more expensive and difficult to get to Solu Khumbu than to the Annapurna Area.
Solu Khumbu is popular not only for its proximity to the Everest (8848m), but also for its habitants, Sherpa villages and monasteries. The nominal destination of an Everest trek is the Everest Base Camp at an elevation of about 5340m, from there to Kala Patthar, a 5545m bump on the southern flank of pumori (7145m), and there is a dramatic view of Everest.
Other than the problem of access, the other major complication to an Everest trek is the high likelihood of Acute Mountain Sickness (AMS). Climbing too quickly to a high elevation causes this potentially deadly disease, commonly known as altitude sickness. From Tengpoche one will have an excellent view of Everest and its more spectacular neighbor Ama Dablam (6856m).
An Everest trek involves a tremendous amount of up-and-down walking. A glance at the map will show the reason why. All the rivers in this part of Nepal flow south from Himalayan glaciers, but the trek route proceeds east. Therefore the trail must climb to the ridge that separates two rivers, descend to the river itself, and ascend the next ridge. Even though the trek begins at an elevation of 1860m, on the sixth day it crosses the Dudh Koshi at only 1500m- after considerable uphill and downhill walking. If you total all the uphill climbing, it will come to almost 9000m of elevation gain from Jiri to Everest Base Camp. The jiri road saves almost 400m of uphill walking over the old approach from Lamosangu, but this is still a long, hard trek with a lot of uphill walking.
