Ganga River – The Largest and Longest River in India

When people search for the largest river in India or the longest river in India, one name always stands above the rest – the Ganga River. Known as “Ganga Maa” by millions of Indians, this river is not only a natural wonder but also the lifeline of northern India. Flowing across more than 2,500 kilometers, the Ganga nourishes vast plains, supports agriculture, sustains industries, and inspires spiritual devotion. The river is considered sacred in Hinduism and holds immense significance in Indian culture, history, and daily life.

In this detailed guide, we will explore the journey of the Ganga River – the largest and longest river in India. From its icy Himalayan origins to the world’s largest delta, from cultural traditions to modern environmental challenges, here is everything you need to know about the river that defines India.

Origin of the Ganga River

The Ganga River begins its journey from the Gangotri Glacier in the Himalayas, located in Uttarakhand. The glacier gives birth to a stream called Bhagirathi, which is considered the true source of the river. As it flows down the mountains and joins with the Alaknanda River at Devprayag, it officially becomes the Ganga.

• Source: Gangotri Glacier, Uttarakhand

• Elevation: Approx. 4,100 meters above sea level

• Total Length: Around 2,525 km (longest in India)

• Countries Covered: India and Bangladesh

From its snowy Himalayan beginnings, the Ganga flows through the fertile Indo-Gangetic plains and finally empties into the Bay of Bengal, forming the Sundarbans Delta, the largest delta in the world.

Course and States Covered

The Ganga River passes through multiple states, providing water, food, and livelihood to millions.

• Uttarakhand – Birthplace of the river (Gangotri Glacier, Devprayag, Rishikesh, Haridwar).

• Uttar Pradesh – The heart of the Ganga basin, covering cities like Kanpur, Allahabad (Prayagraj), and Varanasi.

• Bihar – The river continues eastwards, enriching fertile lands.

• Jharkhand – Short passage through Sahibganj region.

• West Bengal – The river branches into distributaries (Hooghly, Padma) and meets the Bay of Bengal.

In Bangladesh, the river is called the Padma, before merging with the Brahmaputra and Meghna rivers.

Cultural and Religious Importance of the Ganga

The Ganga is not just a river – it is worshipped as a goddess in Hinduism. For thousands of years, it has been central to rituals, festivals, and pilgrimages.

• Haridwar – Devotees take a holy dip to wash away sins.

• Varanasi (Kashi) – Considered the holiest city on the banks of the Ganga. Hindus believe dying here ensures liberation (moksha).

• Ganga Aarti – Every evening, grand aarti ceremonies in Haridwar, Rishikesh, and Varanasi attract tourists and devotees alike.

For Hindus, the river symbolizes purity, spiritual cleansing, and eternal life.
