Mount Everest straddles the Nepal-China border—its summit ridge is the international boundary. Neither country includes the summit within a national park, though both protect surrounding areas.
Established 1976, UNESCO World Heritage 1979. Covers 1,148 km². Boundary stops at the summit ridge. The park includes Everest's southern approaches (Khumbu Glacier, Icefall, Western Cwm, South Col) but the summit itself lies on the border, not within the park's legal description. Key peaks inside: Lhotse (4th highest), Nuptse, Ama Dablam, Thamserku.
Established 1988, expanded 2000. Covers 33,800 km² — massive. Also excludes the summit ridge. Protects northern approaches (Rongbuk Glacier, North Col, Northeast Ridge). Administered by Tibet Autonomous Region. Less tourism infrastructure; stricter access permits.
Both parks enforce regulations on their sides: permits, waste management (Nepal: "leave no trace" deposit system; China: mandatory cleanup), guide requirements, seasonal restrictions. The Sagarmatha Pollution Control Committee (SPCC) manages Khumbu waste. China limits North Side permits (~300/year vs. Nepal's ~400+).
ICIMOD (International Centre for Integrated Mountain Development) facilitates science/policy dialogue. Climate monitoring, glacial lake outburst flood (GLOF) early warning, biodiversity corridors — shared challenges requiring shared solutions.
Everest's summit belongs to no park — it belongs to the atmosphere. But its living slopes are guarded by two nations' highest conservation designations, a rare alignment in a fractured world.
