The Ganga is India’s most revered river, a lifeline for millions of people and a central figure in Hindu belief, and its waters flow from the Himalayas to the Bay of Bengal across a vast and fertile plain. It is worshipped as the goddess Ganga, yet it is also a working river that supports farming and trade along its course.
Origin and course
The river begins as the Bhagirathi at the Gangotri Glacier in Uttarakhand and becomes the Ganga at Devprayag, where it meets the Alaknanda. It then passes Haridwar and Prayagraj, where it joins the Yamuna, and continues through Varanasi and Patna before entering Bangladesh and reaching the Bay of Bengal through the Sundarbans delta, one of the largest deltas in the world.
Mythology and religious importance
According to legend, King Bhagiratha performed severe penance to bring the river down from heaven, and Lord Shiva caught her in his hair to soften the force of her fall. Many Hindus believe that a dip in the Ganga washes away sins, and the river features in rituals from birth to cremation.
Famous places and festivals
Varanasi is known for its ghats and the evening Ganga Aarti, a ceremony of lamps and chants that draws pilgrims and visitors.
Haridwar and Prayagraj host the Kumbh Mela, which brings together saints and devotees for a holy dip in the river.
Rishikesh draws travellers who come for yoga retreats and river rafting along the upper stretch.
Wildlife and livelihoods
The Ganga basin supports farming across the northern plains, and the river is home to the Gangetic dolphin, which India has declared its national aquatic animal. Fishing communities and boatmen also depend on the river, so its health affects daily life far beyond religion.
Pollution and cleaning efforts
Industrial waste and untreated sewage have placed heavy pressure on the river, and the Ganga Action Plan of 1986 was among the first major attempts to clean it. The Namami Gange programme, launched in 2014, continues that work through sewage treatment and riverfront development, although progress remains a matter of public debate.
Interesting facts about the Ganga
Varanasi is considered one of the world’s oldest continuously inhabited cities.
Many Hindu households keep Gangajal at home because it is regarded as pure and auspicious.
The river is one of the most important in Indian history, as several ancient cities and empires grew along its banks.
Why the Ganga still matters
The Ganga remains a symbol of faith and survival, and protecting it is as much a civic duty as a spiritual one.
