A typical expedition to climb Mount Everest via the standard South Col route takes approximately 50–55 days. This includes arriving in Kathmandu and obtaining permits, trekking to Everest Base Camp and acclimatizing for several weeks, climbing through different camps to acclimate and rest, making a summit push, descending back to lower camps, and finally returning to Kathmandu. However, the actual duration may vary depending on factors such as weather conditions, acclimatization schedule, and the climbers' experience and fitness level. It's important to note that climbing Mount Everest is a challenging and dangerous endeavor, and proper preparation, safety protocols, and experienced guides are crucial for a successful and safe climb.
