Everest region

The Solu Khumbu region is the second-most popular trekking area in Nepal. It would be probably  the most popular destination, but it is more expensive and difficult to  get to Solu Khumbu than to the Annapurna area. To get near Everest, you must either walk for a week or fly to Lukla, a remote airstrip where flights are notoriously unreliable.

The other major complication is the altitude sickness because of the high elevated access point Lukla (if you don't walk in from Jiri). So be aware of this and read more in the section about this...

Solu Khumbu is not only famous for the highest mountain on earth, Mount Everest, but also for its Sherpa villages and monasteries. The normal goal for trekkers is the Everest Base Camp, but you cannot see Everest from there, so you have to climb Kala Pattar, a 5545m bump on the southern flank of Pumori.

If you want to avoid a little bit the masses, the trek to Gokyo and ascend of Gokyo Ri is an alternative with also very good views of Mount Everest and Cho Oyu.

To avoid the risk of getting altitude sick, you can make other worthwile treks to less ambitious destinations such as Namche Bazaar, Khumjung or Thami, which are more typical Sherpa villages; or Tengboche with its famous monastery.
