This is a route taken by Sir Edmund Hillarie and Tenzing in 1953 for the conquest of Mt. Everest. This trail provides a classic trekking experience in the Himalayas offering enchanting sights of Lukla trail in the higher Khumbu and relaxed observation of the diverse flora and fauna in the mid altitude regions on the approach to the Khumbu valley, the famed Everest territory. The final leg of this trek is quite strenuous with a series of ascents and descents, trekking against the ''grain' of the Himalayas. However, these challenges are softened by traditional exquisite tea houses, small hamlets of hardy mountain people and monasteries on the back drop of towering Himalayas, to make it one of the most delightful treks in Nepal.
