Wanderlust World Wanderlust World A typical Mount Everest expedition takes about two months from arrival at Base Camp to safe return. The ascent alone usually requires 35–40 days, allowing for crucial acclimatization rotations up and down the mountain. The descent from summit to Base Camp takes roughly 20–25 days.
Weather windows, altitude sickness, route congestion, and individual fitness cause significant variation. Some climbers need longer; others, especially with supplemental oxygen and experienced Sherpa support, may move faster. But two months is the standard planning horizon for a safe, commercially guided climb.
