11. Mount Everest (Nepal/China): Permits, Safety, & Environmental Controls

Access to Mount Everest's base camps and summit is highly regulated by both Nepalese and Chinese authorities. Climbing permits are expensive and limited, requiring significant experience. China's side, in particular, has sometimes restricted access to Everest Base Camp for non-climbers and implemented stricter waste management rules due to environmental concerns. These measures are driven by safety (reducing congestion and accidents) and environmental preservation (managing human waste and pollution) on the world's highest peak.
