Mount Everest and EBC trek
Sagarmatha (« forehead of the sky » in Nepali) or Chomolungma (« mother goddess of the mountains » in Tibetan), 8,848.86m officially since the joint Sino-Nepalese remeasurement of December 2020 — the roof of the world. The trek to Base Camp (EBC, 5,364m) starts from the tiny Lukla airfield (2,860m, landing ranked among the world's most dangerous, 527m runway sloped at 12 % facing a cliff) after a 30-min Twin Otter flight from Kathmandu. 12-14 days round trip via Phakding, Namche Bazaar (2 acclimatisation nights), Tengboche (monastery), Dingboche, Lobuche, Gorak Shep and EBC, with ascent of Kala Patthar (5,643m) for the iconic Everest view. Tea houses every 3-4km, no tent needed.
Everest's summit was first reached on 29 May 1953 at 11:30 by New Zealander Edmund Hillary and Nepalese Sherpa Tenzing Norgay — without artificial oxygen sharing, no GPS, in wool and cotton kit. Tenzing eventually revealed in 1955 (10 years later) that it was he who stepped first but that he and Hillary had sworn to keep the secret to honour the rope-team spirit. Since 1953, over 6,000 people have reached the summit, and over 330 have died there — most buried on site because bringing the body down is technically impossible and costs ~USD 70,000.
