The Khumbu or Everest region is the most well-known trekking area in Nepal. It would probably be the most popular destination, but it is more difficult to get to Solu Khumbu than to the Annapurna area. To get near Everest, you must either walk for 10 days or fly to Lukla, a remote mountain airstrip where flights are notoriously unreliable. Solu Khumbu is justifiably famous, not only for its proximity to the world’s highest mountain (8848 metres), but also for its Sherpa villages and monasteries. The primary goal of an Everest trek is the Everest base camp at an elevation of about 5340 metres. However, you cannot see Everest from the base camp so most trekkers climb Kala Pattar, an unassuming 5545-metre bump on the southern flank of Pumori (7145 metres.)
