Nathula was closed for 44 years following the 1962 Sino-Indian War and was only reopened for trade in 2006.
The name 'Nathu' means 'listening ears' and 'La' means 'pass' in Tibetan.
Despite the high altitude, the road leading to the pass is one of the highest motorable roads in the world.
Temperature here frequently drops below freezing, even during summer months.
The pass is a part of a network of passes that historically facilitated the exchange of wool, fur, and medicinal herbs between India and Tibet.
Oxygen levels at the pass are approximately 50% of those found at sea level.
Nathula Pass is a high-altitude mountain pass in the Himalayas connecting the Indian state of Sikkim with the Tibet Autonomous Region of China. Situated at an elevation of 14,140 feet (4,310 meters), it is one of the three open trading border posts between India and China. The pass historically served as a critical branch of the ancient Silk Road. The site features a permanent military presence and restricted access zones managed by the Indian Army. Visitors can view the international border fence and observe soldiers from both nations stationed at the boundary. The terrain is characterized by rugged, rocky slopes and alpine flora with limited oxygen levels due to the high altitude. It remains a site of strategic geopolitical importance and diplomatic significance. Access is strictly controlled through mandatory protected area permits for all non-local visitors.
