Passes of the Himalayas and Their Significance
Geography › India: Location, Geology and the Himalayas · Topic 13.8
Himalayan passes are natural gaps in the mountain ranges that allow the movement of people, goods and armies across the barrier. Important passes include Banihal, Zoji La and Khardung La in Jammu and Kashmir and Ladakh, Rohtang, Bara Lacha La and Shipki La in Himachal Pradesh, Lipulekh and Niti in Uttarakhand, and Nathu La and Jelep La in Sikkim. Most close in winter.

Where Does It Fit?
This is the last topic of the macro on India’s location, geology and the Himalayas. The previous topic covered the valleys and glaciers, and this one lists the gaps through the mountain wall. The next macro covers the plains, plateau, coasts and islands, beginning with the Indo-Gangetic-Brahmaputra plain. Previous topic: Himalayan Valleys, Snowline and Glaciers. Next topic: Indo-Gangetic-Brahmaputra Plain.
What Are Himalayan Passes and Why Do They Matter?
In short: a pass is a low point on a ridge, and in the Himalayas it is the only way for roads, trade and pilgrims to cross.
The Himalayas are a barrier for movement as well as for the monsoon, as in Himalayan Ranges – Shiwaliks, Lesser, Greater and Trans-Himalaya. A pass is a natural gap or a saddle in a mountain range, normally at the head of a river valley. Passes in the Greater Himalaya are often above 4,500 m and are snowbound for much of the year, so most of them are open for only a few months, from about May to October. Their importance is strategic, because they decide the lines of defence and the routes of invasion; economic, because they carry the border trade and the road network; and cultural, because they carry pilgrimage routes. Tunnels now bypass several of the passes to allow year-round movement.
Which Are the Important Passes of the Western Himalaya?
| Pass | State or region | Connects and notes |
|---|---|---|
| Banihal Pass | Jammu and Kashmir (Pir Panjal range) | Jammu with the Kashmir valley, at about 2,830 m; the Jawahar Tunnel (1956) takes the road below the pass, and the Banihal–Qazigund railway tunnel opened in 2013 |
| Zoji La | Jammu and Kashmir and Ladakh | Srinagar with Kargil and Leh on the national highway; closed from about December to May; the Zojila tunnel, 13.15 km, is being built to give all-weather access, and its completion has been pushed to 2028 |
| Khardung La | Ladakh | Near Leh in the Ladakh range, about 5,600 m; one of the highest motorable roads in the world; leads to the Nubra valley |
| Chang La | Ladakh | About 5,360 m; links Leh with the Pangong Tso region |
| Rohtang Pass | Himachal Pradesh | Links the Kullu valley with Lahaul and Spiti, at about 3,980 m; the 9-km Atal Tunnel, opened in 2020, now gives all-weather access |
| Bara Lacha La | Himachal Pradesh and Ladakh | About 4,890 m, on the Manali–Leh highway |
| Shipki La | Himachal Pradesh | On the border with Tibet, on the Sutlej route; the Hindustan–Tibet road |
Which Are the Passes of the Central and Eastern Himalaya?
| Pass | State | Connects and notes |
|---|---|---|
| Lipulekh | Uttarakhand | Tri-junction of India, Tibet and Nepal; route of the Kailash Mansarovar Yatra and an old trade route |
| Niti and Mana | Uttarakhand | Garhwal to Tibet; Mana lies near Badrinath |
| Mangsha Dhura | Uttarakhand | Pilgrim route to Kailash-Mansarovar |
| Nathu La | Sikkim | Sikkim with Tibet at about 4,310 m, part of an old branch of the Silk Route; closed after the 1962 war and reopened for trade in 2006 |
| Jelep La | Sikkim | Sikkim with Tibet via the Chumbi valley, linking Kalimpong with Lhasa |
| Bum La, Sela and Bomdi La | Arunachal Pradesh | Tawang and West Kameng region; the Sela Tunnel, opened in 2024, gives all-weather access to Tawang |
The passes have regained importance in recent years. Border trade between India and China through Nathu La, Shipki La and Lipulekh, which had stopped in 2020, resumed on 1 August 2026, with seasonal trade lasting until the passes close in November. Nepal has objected to the use of Lipulekh, citing its own claim to the area. The Kailash Mansarovar Yatra, which is organised by the Ministry of External Affairs each summer, ran in 2026 through two routes, Lipulekh in Uttarakhand and Nathu La in Sikkim.
How Do You Study the Passes?
- By state: group each pass under Jammu and Kashmir, Ladakh, Himachal, Uttarakhand, Sikkim and Arunachal Pradesh, since the questions give the state and ask for the pass.
- By the neighbour: Shipki La, Lipulekh, Niti, Mana, Nathu La, Jelep La and Bum La lead to Tibet in China, and the passes of the Pir Panjal connect valleys within India.
- By function: road passes (Zoji La, Rohtang, Bara Lacha La), trade passes (Nathu La, Shipki La, Lipulekh) and pilgrimage passes (Lipulekh, Nathu La, Mangsha Dhura).
As an analytical point, the tunnels such as the Atal and Sela, and the planned Zojila, are converting the seasonal gaps into permanent links, which improves the defence logistics and the economy of the hill regions, but also brings more traffic, construction and waste to a fragile environment. They need to be assessed along with the risk of landslides and the glacier hazards discussed in Himalayan Valleys, Snowline and Glaciers.

Frequently Asked Questions
What are the important passes of the Himalayas?
The important Himalayan passes include Banihal, Zoji La, Khardung La and Chang La in Jammu and Kashmir and Ladakh, Rohtang, Bara Lacha La and Shipki La in Himachal Pradesh, Lipulekh, Niti and Mana in Uttarakhand, and Nathu La and Jelep La in Sikkim.
Which pass connects Srinagar with Leh?
The Zoji La pass connects Srinagar with Kargil and Leh on the national highway. It is closed by heavy snow from about December to May, so a 13-kilometre tunnel is being built to give all-weather access, with completion now expected in 2028.
What is the Atal Tunnel?
The Atal Tunnel is a road tunnel of about 9 kilometres under the Rohtang Pass in Himachal Pradesh, opened in 2020. It provides all-weather road connectivity between the Kullu valley and Lahaul and Spiti, and shortens the distance on the Manali to Leh route.
Through which passes is the Kailash Mansarovar Yatra conducted?
The Kailash Mansarovar Yatra is conducted by the Ministry of External Affairs each summer through two routes, the Lipulekh Pass in Uttarakhand and the Nathu La Pass in Sikkim. The Yatra ran again in 2026 with about one thousand pilgrims planned in total.
Which passes are used for India–China border trade?
India–China border trade is conducted through three passes: Nathu La in Sikkim, Shipki La in Himachal Pradesh and Lipulekh in Uttarakhand. Trade through them, which was suspended in 2020, resumed in August 2026 on a seasonal basis, and the passes close for the winter in November.
