Korala or Kora La or Koro La (Nepali: ; literally Kora Pass) is a mountain pass between Tibet and Upper Mustang. At only in elevation, it has been considered the lowest drivable path between Tibetan Plateau and the Indian subcontinent. It is currently being planned as a vehicle border crossing between China and Nepal. Geography Korala is situated on the drainage divide between the Yarlung Tsangpo and Ganges river basins. At , it is the lowest pass across the Himalayan mountain range. As such, it forms the key col for K2 on the ridgeline connecting it to Mount Everest. The Kali Gandaki River has its source near the southern side of the pass. History Korala is one of the oldest routes between the two regions.
