Nathula Pass in East Sikkim, at 4,310 m above sea level, is one of only three open land-border crossings between India and China. Located 54 km east of Gangtok on the ancient Silk Road, it carries deep military history — including the decisive 1967 Battle — and was reopened for bilateral trade in 2006, making it a rare destination where history, geopolitics, and Himalayan grandeur converge.

A Glimpse into the History of Nathula Pass
Ancient Silk Road Corridor
Nathula — meaning "Listening Ears Pass" in Tibetan — was a primary Himalayan artery on the ancient Silk Road for centuries. Wool, salt, grain, borax, and silk moved between India and Tibet through this 4,310 m pass, with Tibetan traders and their yak caravans resting at Tsomgo Lake below before the final ascent.
The 1967 Battle of Nathu La
In September 1967, Chinese forces attempted a major incursion at Nathula. The Indian Army repelled the attack in a fierce, multi-day battle that resulted in significant casualties on both sides. The victory — decisively in India's favour — is less celebrated than 1962 but strategically pivotal, proving the Army's capability on high-altitude terrain.
Trade Reopening (2006)
India and China formally reopened Nathula for bilateral trade in July 2006 — the first overland commerce between the two nations since the 1962 war. Today, Indian tourists (with permits) can walk up to the demarcated gate and observe Chinese soldier posts just metres away, making it one of the most unusual tourist experiences in Asia.
Significance of Nathula Pass
Nathula is one of only three formally open land crossings between India and China (alongside Shipkila in Himachal Pradesh and Lipulekh in Uttarakhand). The pass remains a sensitive military zone managed by the Indian Army; tourists may spend no more than 30–60 minutes at the summit due to altitude and security protocols. Indian and Chinese soldiers exchange handshakes and sweets at ceremonial border meetings held between June and November.
Events at Nathula Pass
India–China Border Trade Season
Each year from May to November, designated trade days at Nathula see small convoys of traders cross under a bilateral agreement. Indian goods — including agricultural produce — are exchanged for Tibetan commodities. The rare sight of formalised cross-border commerce at this altitude draws journalists and curious visitors each trading season.
Baba Harbhajan Singh Memorial Ceremony
Every year, the Indian Army holds a remembrance puja at the Baba Harbhajan Singh Memorial Temple (located ~10 km from the pass). Both soldiers and civilians attend to honour this legendary army personnel, believed by troops to still guard the border. The ceremony draws hundreds of pilgrims from across India.
Did You Know?
Nathula Pass is accessible only to Indian nationals with a Protected Area Permit — foreign nationals are restricted to Tsomgo Lake and cannot proceed further. The pass closes entirely to civilian visitors from December to May each year due to snowfall that can exceed 3 metres. On a clear day from the summit gate, you can see the Chumbi Valley of Tibet stretching northward beyond the border, a view that fewer than a few thousand tourists witness each year.
