Ladakh & Jammu–Kashmir
Zoji La — 3,528 m
State / UT: Ladakh / J&K
Elevation: 3,528 m
Connects: Srinagar (Kashmir Valley) ↔ Dras, Kargil and Leh — on NH-1
Why it matters: The monsoon’s wall and the army’s lifeline: Ladakh’s only all-weather road link runs through it, yet heavy snow shuts it for months. The under-construction Zojila Tunnel — set to be Asia’s longest bi-directional tunnel — is meant to end that isolation.
Banihal Pass — 2,832 m
State / UT: J&K
Elevation: 2,832 m
Connects: Jammu ↔ Kashmir Valley, across the Pir Panjal Range
Why it matters: Trains and cars no longer climb it: the Jawahar Tunnel (1956) and the newer Banihal–Qazigund tunnel (2021) bore straight beneath. It is the classic answer to ‘which pass connects Jammu with the Kashmir Valley’.
Pir Panjal Pass — ~3,490 m
State / UT: J&K
Elevation: ~3,490 m
Connects: Rajouri–Poonch ↔ Kashmir Valley, on the historic Mughal Road
Why it matters: The route Mughal emperors took to their beloved Kashmir. It gives its name to the entire Pir Panjal Range — the outer Himalayan wall that wrings the rain out and shelters the valley behind.
Khardung La — ~5,359 m (signboards claim 5,602 m)
State / UT: Ladakh
Elevation: ~5,359 m (signboards claim 5,602 m)
Connects: Leh ↔ Nubra Valley and onward to the Siachen Glacier
Why it matters: Long advertised as the world’s highest motorable pass — a claim other Ladakhi passes now contest. Strategically it is far more than a tourist trophy: it is the supply road to Siachen, the highest battlefield on Earth.
Chang La — ~5,360 m
State / UT: Ladakh
Elevation: ~5,360 m
Connects: Leh ↔ Pangong Tso and the Changthang plateau
Why it matters: The gateway to Pangong Tso and the Changthang cold desert, home of the Changpa nomads and their pashmina goats. Its high, thin air makes it one of the toughest drives in the country.
Fotu La — 4,108 m
State / UT: Ladakh
Elevation: 4,108 m
Connects: Kargil ↔ Leh — the highest point on the Srinagar–Leh highway
Why it matters: Higher than the more famous Zoji La on the same road, yet less troublesome: it stays open longer because it lies in Ladakh’s rain-shadow, where there is simply less snow to block it.
Karakoram Pass — 5,540 m
State / UT: Ladakh
Elevation: 5,540 m
Connects: Ladakh (Daulat Beg Oldi) ↔ Xinjiang, China — on the Line of Actual Control
Why it matters: For centuries the great caravan gate on the Ladakh–Yarkand silk route, littered with the bones of pack animals. It gives the Karakoram Range its name and today sits on one of India’s most sensitive frontiers, near the Daulat Beg Oldi airstrip.
Aghil Pass — ~5,000 m
State / UT: Ladakh
Elevation: ~5,000 m
Connects: Ladakh ↔ the Shaksgam Valley, north of the Karakoram Range
Why it matters: Beyond the Karakoram watershed, it leads into the Shaksgam (Trans-Karakoram) tract — territory India claims but which Pakistan ceded to China in 1963, an act India has never recognised.
Saser La — 5,411 m
State / UT: Ladakh
Elevation: 5,411 m
Connects: Nubra Valley ↔ Depsang plains, on the old Leh–Yarkand trade route
Why it matters: The first great obstacle on the historic caravan road to Central Asia, notorious for its glaciers. It guards the approach to the Depsang plains — a name that returns to the headlines with every India–China standoff.
Burzil Pass — ~4,100 m
State / UT: J&K
Elevation: ~4,100 m
Connects: Kashmir Valley ↔ Gilgit, via the Deosai plains
Why it matters: The historic road from Srinagar to Gilgit, crossing the Deosai plateau — the ‘Land of the Giants’, among the highest plateaus on Earth. It runs into territory that is Indian on the official map and under Pakistani occupation on the ground.
Khunjerab Pass — 4,693 m
State / UT: Gilgit-Baltistan (Indian territory under Pakistani occupation)
Elevation: 4,693 m
Connects: Gilgit-Baltistan ↔ Xinjiang, China — the Karakoram Highway crossing
Why it matters: The highest paved border crossing in the world, and the spine of the China–Pakistan Economic Corridor. India protests the CPEC precisely because the highway runs through territory that is legally India’s — which is why this pass appears on India’s official map.
Himachal Pradesh
Rohtang Pass — 3,978 m
State / UT: Himachal Pradesh
Elevation: 3,978 m
Connects: Kullu Valley ↔ Lahaul & Spiti, on the Manali–Leh highway
Why it matters: Its name means ‘pile of corpses’ — a memory of travellers caught by its storms. The Atal Tunnel (2020), 9.02 km beneath it, now keeps Lahaul connected all winter and cuts the journey by roughly four hours.
Shipki La — ~4,300 m
State / UT: Himachal Pradesh
Elevation: ~4,300 m
Connects: Kinnaur ↔ Tibet, along the Sutlej gorge
Why it matters: The pass where the Sutlej enters India from Tibet — the single most examined fact about it. One of the designated India–China border trade posts, it is also a proposed Kailash Mansarovar route.
Bara-lacha La — 4,890 m
State / UT: Himachal Pradesh
Elevation: 4,890 m
Connects: Lahaul ↔ Ladakh (Zanskar), on the Manali–Leh highway
Why it matters: A rare four-way junction of valleys — Lahaul, Zanskar, Spiti and Ladakh meet here. Nearby Suraj Tal, one of India’s highest lakes, feeds the Bhaga river.
Kunzum La — 4,551 m
State / UT: Himachal Pradesh
Elevation: 4,551 m
Connects: Lahaul ↔ Spiti Valley
Why it matters: The only road link into Spiti from Lahaul, and the doorway to the Chandratal lake. Snowbound roughly half the year, it seals Spiti into one of the most isolated inhabited valleys in the Himalaya.
Uttarakhand
Lipulekh Pass — 5,334 m
State / UT: Uttarakhand
Elevation: 5,334 m
Connects: Pithoragarh (Kumaon) ↔ Taklakot, Tibet — the Kailash Mansarovar route
Why it matters: The oldest and shortest pilgrim road to Kailash Mansarovar, and one of India’s designated China trade posts. It sits at the India–Nepal–China tri-junction, at the heart of the Kalapani territorial dispute with Nepal.
Mana Pass — 5,632 m
State / UT: Uttarakhand
Elevation: 5,632 m
Connects: Chamoli (beyond Badrinath) ↔ Tibet
Why it matters: Among the highest vehicle-accessible passes on the planet, reached through Mana — long billed as India’s last village and now rebranded the ‘first village’. The ancient Indo-Tibetan wool route ran through here.
Niti Pass — 5,068 m
State / UT: Uttarakhand
Elevation: 5,068 m
Connects: Chamoli (Niti Valley) ↔ Tibet
Why it matters: A busy Bhotiya trade route until the 1962 war shut it for good. The Rishiganga and the Nanda Devi Biosphere lie in its shadow — the same valley that made news in the 2021 Chamoli disaster.
Sikkim & the North-East
Nathu La — 4,310 m
State / UT: Sikkim
Elevation: 4,310 m
Connects: Gangtok ↔ Chumbi Valley, Tibet
Why it matters: An old Silk Route branch, sealed after 1962 and reopened for trade in 2006 — one of only three designated India–China trading posts, and a Kailash Mansarovar route. It overlooks the Chumbi Valley, the dagger pointed at India’s Siliguri Corridor.
Jelep La — 4,267 m
State / UT: Sikkim
Elevation: 4,267 m
Connects: Sikkim (Zuluk) ↔ Chumbi Valley, Tibet
Why it matters: Once the main wool-and-tea road to Lhasa, it has stayed shut since 1962 while its neighbour Nathu La reopened. The switchback climb to it — the Zuluk loops — is among the most spectacular roads in India.
Sela Pass — 4,170 m
State / UT: Arunachal Pradesh
Elevation: 4,170 m
Connects: Tezpur/Bomdila ↔ Tawang
Why it matters: The only road to Tawang, and the site of a bitter 1962 battle. The Sela Tunnel, inaugurated in 2024, now gives the army all-weather access to the Tawang sector — one of the most contested stretches of the LAC.
Bomdi La — ~2,600 m
State / UT: Arunachal Pradesh
Elevation: ~2,600 m
Connects: Assam plains ↔ Tawang, via West Kameng
Why it matters: The lower gate on the Tawang road, and the last town to fall in the 1962 war before China’s unilateral ceasefire. Its Buddhist monastery and orchid sanctuary make it the softer face of a hard frontier.
Diphu Pass — ~4,587 m
State / UT: Arunachal Pradesh
Elevation: ~4,587 m
Connects: Eastern Arunachal ↔ Tibet and Myanmar
Why it matters: A tri-junction of India, China and Myanmar. India and Myanmar treat it as the meeting point of their frontiers; China disputes the alignment — a small pass carrying an outsized quarrel.
Pangsau Pass — 1,136 m
State / UT: Arunachal Pradesh
Elevation: 1,136 m
Connects: Changlang, Arunachal ↔ Myanmar (Kachin) — on the Stilwell Road
Why it matters: The Allies drove the Stilwell (Ledo) Road through it in the Second World War to supply China. Beside it lies the Lake of No Return, where lost aircraft and exhausted refugees vanished — a candidate for reopening India–Myanmar trade.
Peninsular Ghats & Aravalli
Palakkad (Palghat) Gap — ~140 m; 30–40 km wide
State / UT: Kerala / Tamil Nadu
Elevation: ~140 m; 30–40 km wide
Connects: Coimbatore (Tamil Nadu) ↔ Palakkad and central Kerala
Why it matters: The great breach in the Western Ghats, between the Nilgiris and the Anaimalais. It funnels the south-west monsoon inland — watering Palakkad’s paddy while leaving Coimbatore in a rain-shadow — and carries the main road and rail links into Kerala.
Shencottah (Senkottai) Gap — ~200 m
State / UT: Kerala / Tamil Nadu
Elevation: ~200 m
Connects: Madurai / Tirunelveli ↔ Kollam, southern Kerala
Why it matters: The southern gap in the Ghats, between the Cardamom Hills and the Ashambu Hills. It lets some monsoon rain — and the Kollam–Madurai railway — slip through to the rain-starved Tamil plains.
Thal Ghat (Kasara Ghat) — ~580 m
State / UT: Maharashtra
Elevation: ~580 m
Connects: Mumbai ↔ Nashik and the Deccan plateau
Why it matters: One of the two historic staircases from the Konkan coast up to the Deccan. The Mumbai–Nashik–Agra road and the central railway both climb it — the reason Mumbai’s hinterland trade could ever exist.
Bhor Ghat — ~450 m
State / UT: Maharashtra
Elevation: ~450 m
Connects: Mumbai / Panvel ↔ Pune, via Khandala–Lonavala
Why it matters: The Deccan’s other great stairway, carrying the Mumbai–Pune expressway and railway. Its 19th-century rail incline was an engineering epic — and it made Pune an extension of Mumbai’s economy.
Haldighati Pass — ~600 m
State / UT: Rajasthan (Aravalli)
Elevation: ~600 m
Connects: Rajsamand ↔ Udaipur, through the Aravalli Range
Why it matters: Not a Himalayan giant but a history-maker: the 1576 battle between Maharana Pratap and Akbar’s forces was fought in this narrow defile. Its yellow turmeric-coloured soil gives the pass its name.

Nathu La reopened for India–China border trade in 2006. Its neighbour Jelep La has remained closed since the 1962 war.
Frequently Asked Questions
What is a mountain pass?
A mountain pass is a navigable gap or saddle across a mountain range — the lowest crossing point between two valleys. Passes decide where roads, railways, armies, pilgrims and trade can move, which is why they shape settlement, strategy and even climate: gaps like the Palakkad Gap let monsoon winds through a range that otherwise blocks them.
Which mountain passes connect India and China?
The main crossings are Karakoram Pass and Aghil Pass (Ladakh), Shipki La (Himachal Pradesh), Lipulekh, Mana and Niti passes (Uttarakhand), Nathu La and Jelep La (Sikkim), and Diphu Pass (Arunachal Pradesh). Of these, Shipki La, Lipulekh and Nathu La are the three designated border-trade posts.
Which passes are most important for UPSC Prelims?
Prioritise Zoji La, Banihal, Khardung La and Karakoram Pass (Ladakh & J&K); Rohtang, Shipki La, Bara-lacha La and Kunzum La (Himachal); Lipulekh, Mana and Niti (Uttarakhand); Nathu La and Jelep La (Sikkim); Se La, Bomdi La and Diphu (Arunachal); and the peninsular gaps — Palakkad, Shencottah, Thal Ghat and Bhor Ghat. Questions usually ask what a pass connects, or to arrange passes from west to east. The same content also appears in State PSC papers, SSC General Awareness and CDS/NDA.
How should I remember the passes from west to east?
Move along the Himalaya in order: Khunjerab and Burzil (Gilgit-Baltistan) → Zoji La, Banihal, Pir Panjal, Khardung La, Chang La, Saser La, Karakoram, Aghil (J&K and Ladakh) → Rohtang, Kunzum, Bara-lacha La, Shipki La (Himachal) → Mana, Niti, Lipulekh (Uttarakhand) → Nathu La, Jelep La (Sikkim) → Se La, Bomdi La, Pangsau, Diphu (Arunachal). Use the Index panel on the map to drill this sequence.
Why is the Palakkad Gap so important?
At only about 140 m high and 30–40 km wide, it is the biggest breach in the Western Ghats. It carries the main road and rail routes between Tamil Nadu and Kerala, and it funnels south-west monsoon winds inland — enriching Palakkad’s paddy country while leaving Coimbatore in a comparative rain-shadow.
Does this map show the correct boundaries of India?
Yes. The map is drawn from the India point-of-view boundary dataset, showing India as the Government of India depicts it — with the full territories of Jammu & Kashmir and Ladakh, including Gilgit-Baltistan, Pakistan-occupied Kashmir and Aksai Chin. That is why passes such as Khunjerab and Burzil, which lie in Indian territory under Pakistani occupation, appear on this map.
