Mountain passes are natural routes through mountains that connect one region to another. In India, these passes have played a significant role in trade, travel, and defence since ancient times. They serve as essential gateways linking different states and even neighbouring countries. Mountain passes are often used by travellers, traders, and the Indian Army to cross high, rugged terrain. India, with its diverse landscape and mighty mountain ranges like the Himalayas, Karakoram, and Western Ghats, has many such vital passes.
Some are open all year, while others remain closed during winter due to heavy snowfall. There are more than 100 mountain passes across India, each with its own geographical and strategic importance. From the famous Zoji La in Jammu and Kashmir to Nathu La in Sikkim and Rohtang Pass in Himachal Pradesh, these routes connect valleys, states, and borders. In this article, we'll take a look at the list of important mountain passes in India, their locations, and why they hold such great significance for the country.

1. Khardung La (Ladakh)
Khardung La, located in Ladakh at an altitude of about 5,359 meters, is one of the world's highest motorable passes. Built and maintained by the Border Roads Organisation, it was opened to vehicles in 1988. The pass connects Leh to the Nubra and Shyok Valleys and serves as the main route to the Siachen Glacier, making it vital for the Indian Army's supply lines.
2. Zoji La (Jammu & Kashmir)
Zoji La lies at 3,528 metres on the Srinagar–Leh Highway, linking the Kashmir Valley with Ladakh. Built during the British era and later improved by the Border Roads Organisation, this pass is the lifeline of Ladakh, ensuring the flow of supplies and troop movement even in harsh weather. It played a significant role in the 1947–48 war when Indian forces secured Ladakh through this route. Due to heavy snowfall, the pass often closes in winter. To address this, the government began construction of the Zoji La Tunnel in 2018 to provide all-weather connectivity to this vital border region.
3. Nathu La (Sikkim)
Nathu La, situated at 4,310 metres, connects Sikkim (India) with Tibet (China). Once part of the ancient Silk Route, it was reopened for trade in 2006 after being closed following the 1962 Indo-China War. It is one of the few officially open border passes between India and China, making it crucial for trade and diplomacy. The Indian Army also uses it for border patrols and logistics.
4. Rohtang Pass (Himachal Pradesh)
Rohtang Pass, located at 3,978 metres near Manali, connects Kullu Valley with Lahaul and Spiti. It has served as a key mountain route for centuries and was later developed by the Border Roads Organisation for military and civilian use. However, due to heavy snowfall, it remained closed for almost half the year. To overcome this, the Atal Tunnel, completed in 2020, was built under Rohtang Pass, ensuring all-season travel between Manali and Leh.
5. Lipu Lekh Pass (Uttarakhand)
Lipu Lekh Pass, at about 5,115 metres, lies at the trijunction of India, Nepal, and China in the Pithoragarh district of Uttarakhand. It has long been a route for trade and the famous Kailash Mansarovar Yatra to Tibet. The pass is of great strategic importance due to its location near the Indo-China border. The Border Roads Organisation maintains access roads that help the Indian Army move troops and supplies efficiently.
Why Mountain Passes Are Important
