The Aravalli Hills — India's ancient mountain spine
The Aravalli Range is one of India's most fascinating mountain systems — not because it is very high, but because it is extraordinarily old. It is among the oldest fold mountain systems on Earth, formed billions of years ago and worn down by immense geological time.
It runs roughly southwest to northeast, from Gujarat through Rajasthan and Haryana towards Delhi, for about 700 km.
Unlike the Himalayas, the Aravallis are not young, towering mountains. They are the much-eroded remnants of a once far greater mountain system.
A range that has witnessed India's history
The Aravallis pass through landscapes associated with some of India's great historical episodes.
Mewar, Udaipur, Chittorgarh and Kumbhalgarh lie within or around the Aravalli landscape.
The hills provided natural protection to the kingdoms of Rajasthan. The rugged terrain was particularly important in the history of Maharana Pratap, whose struggle against the Mughal Empire is inseparable from the forests and hills of Mewar.
The famous Battle of Haldighati took place in an Aravalli pass.
The highest point
The highest summit of the entire Aravalli system is Guru Shikhar, at about 1,722 metres, near Mount Abu in Rajasthan.
Guru Shikhar
Mount Abu itself is an extraordinary contrast to the surrounding dry Rajasthan landscape — a relatively cool, green mountain retreat with forests, rocky formations and lakes.
An ecological barrier
The Aravallis have another extremely important role.
They form a natural ecological barrier between the Thar Desert and the more fertile regions to the east.
Their forests help:
slow desertification
recharge groundwater
regulate local climate
prevent soil erosion
provide habitats for wildlife
The range is therefore much more than a picturesque line of hills.
The hidden water story
Several rivers and streams originate in or around the Aravalli landscape.
The Banas, Luni and Sabarmati river systems are associated with the range, while numerous seasonal streams descend from its slopes.
In a region where water is precious, even these modest hills can determine where settlements and agriculture survive.
A treasure house of minerals
The Aravallis are also extraordinarily rich in minerals.
Historically they have yielded copper, zinc, lead, marble and other minerals.
The famous Khetri copper belt of Rajasthan lies in the Aravalli geological province.
The hills therefore have another story to tell — not just of forests and kingdoms, but of ancient rocks and human mining traditions.
Mountains of sacred traditions
The Aravallis also contain numerous sacred places.
Mount Abu is home to the remarkable Dilwara Jain temples, while many hills and caves across Rajasthan have long associations with Hindu and Jain traditions.
The landscape around Nathdwara, Eklingji and Ranakpur adds another layer of sacred geography to the range.
Wildlife
Despite centuries of human use, parts of the Aravallis still support:
leopard
sloth bear
striped hyena
nilgai
sambar
chital
wild boar
many species of birds
The Sariska landscape is particularly well known for its wildlife.
What makes the Aravallis special?
If the Himalayas tell us the story of young mountains still rising, the Aravallis tell us the story of deep geological time.
They have been mountains for unimaginably long periods, and erosion has gradually sculpted them into today's low, rugged hills.
So perhaps the most beautiful way to introduce them is:
The Himalayas are India's young giants.
The Aravallis are India's ancient survivors.
The Western Ghats, Eastern Ghats and Northeast hills — each with a completely different personality.
