The base camp, located at around 17,600 feet, experiences nearly 50% less oxygen concentration than at sea level, with winter temperatures dropping below freezing at night. The standard 80-mile hike from Lukla to Base Camp and back typically takes 10 to 12 days and involves an elevation gain of over 8,000 feet. Dimple, from Pune, India, prepared her daughter, Arishka, for this challenging trek by going on 5-mile walks near their home for two years before their trip in April.
