Mountain passes are natural gaps or low points in a mountain range that allow movement of people, goods, and armies across the barrier; India's Himalayan and other passes carry both trade and strategic significance.
- Jammu and Kashmir and Ladakh: Zoji La (links Srinagar with Leh, on the Srinagar-Leh highway), Banihal (with the Jawahar tunnel under it), Khardung La (one of the highest motorable passes, north of Leh), and Pir Panjal pass.
- Karakoram and eastern Ladakh: the Karakoram Pass (on the old route to Central Asia and Yarkand) and the strategically sensitive areas near the Line of Actual Control.
- Himachal Pradesh and Uttarakhand: Rohtang and Shipki La (Himachal, the latter on the old India-Tibet trade route and the Sutlej's entry), Niti and Lipulekh and Mana (Uttarakhand, near the China border, used for the Kailash-Mansarovar pilgrimage).
- Sikkim and northeast: Nathu La and Jelep La (Sikkim, on the old Silk Route to Tibet, Nathu La reopened for border trade in 2006), Bomdi La and Diphu (Arunachal), and Bum La near Tawang.
- Many passes lie close to the Line of Actual Control with China, so they are crucial for the Indo-Tibetan Border Police and army logistics, giving the topic a strong security angle.
Pass-to-state and pass-to-route matching (Zoji La, Nathu La, Shipki La, Lipulekh, Bum La), the highest motorable passes, and the link to LAC border management and the ITBP are recurring geography and security facts.
Zoji La (Srinagar-Leh) versus Banihal (Jammu-Srinagar); Nathu La and Jelep La are both in Sikkim on the old Silk Route; Lipulekh, Niti, and Mana are in the Uttarakhand China-border belt, not Himachal.
Himalayan passes (Zoji La, Khardung La, Shipki La, Lipulekh, Nathu La, Bum La) link India's borderlands and are vital for trade and ITBP-army logistics.
