Mt. Everest has been calling out to trekkers and climbers since it first appeared in telescopes of mountain surveyors, and the trails that climb through the foothills of the world's highest mountain still offer some of the most challenging trekking in Nepal. The district Solukhumbu have been extensively developed for trekking, with well-maintained trails and plentiful lodges. But The trekking route start higher and stay higher, touching the tops of some of the most famous mountain in the Himalaya. Most trekkers fly into Lukla, climbing steeply through the mountains of Khumbu to Everest base camp or the sacred lakes at Gokyo. However, you will be better able to deal with the effect of the altitude if you walk in via the trails from Shivalaya (Near Jiri) or Tumlingtar (Near Hile). Because many treks climb above 4500 M, acute mountain sickness (AMS) is a serious risk in this region. It is essential to ascend slowly and take the recommended rest day.
