🏔️ Overview
The Aravalli Range, also spelled Aravali Range, is an ancient mountain system stretching across northwestern India. Running generally from southwest to northeast through Gujarat, Rajasthan, Haryana, and Delhi, the Aravallis form one of the most distinctive physical features of western India.
Unlike the dramatic, snow-covered Himalayas, the Aravallis are a deeply eroded mountain system. Billions of years of geological activity, weathering, and erosion have reduced much of the range to rounded hills, rocky ridges, isolated peaks, plateaus, and rugged escarpments. Even so, the range retains enormous geological importance: the Aravalli–Delhi belt preserves evidence of some of the earliest chapters in the evolution of the Indian continental crust.
The highest point is Guru Shikhar, which rises to 1,722 meters (5,650 feet) near Mount Abu in Rajasthan.
Beyond geology, the Aravallis help shape regional drainage, vegetation, wildlife habitat, settlement patterns, and the transition between the Thar Desert and the more humid landscapes to the east.

Exact figures vary because the northern Aravallis become fragmented into isolated ridges rather than maintaining one continuous mountain front.
📍 Location
The Aravalli Range extends diagonally across northwestern India.
Its southwestern sections lie in Gujarat and southern Rajasthan, where the range includes some of its highest and most rugged terrain. From there, it crosses Rajasthan toward the northeast before continuing as increasingly fragmented hills through Haryana and into the National Capital Territory of Delhi.
Rajasthan contains the largest and most prominent portion of the range. Major places associated with the Aravallis include:
- Mount Abu
- Udaipur
- Ajmer
- Jaipur region
- Alwar
- Kumbhalgarh
- Gurugram
- Southern Delhi
In Delhi, remnants of the ancient mountain system appear as the Delhi Ridge, an important rocky and wooded landscape running through portions of the city.
The range also forms an important physiographic division within Rajasthan. Much of the arid Thar Desert lies to its northwest, while generally more productive and better-watered landscapes occur to its southeast.
📏 Elevation & Highest Peaks
The Aravallis are not especially high by modern mountain standards. Much of the range consists of hills and ridges between a few hundred meters and roughly 1,000 meters above sea level.
The exception is the mountainous region around Mount Abu, where elevations rise considerably higher.
Guru Shikhar — 1,722 m
At 1,722 meters (5,650 feet), Guru Shikhar is the highest point in the Aravalli Range and the highest mountain in Rajasthan. It stands in the Arbuda Mountains near Mount Abu in Sirohi district.
A road climbs much of the way toward the summit area, followed by a stairway leading to the Guru Dattatreya Temple. Rajasthan Tourism describes a climb of roughly 300 steps to reach the temple and viewpoint.
Because the Aravallis comprise an entire mountain system rather than a single summit, prominence, isolation, and nearest higher neighbor are not meaningful measurements for the range as a whole. Those measurements are best applied to individual mountains such as Guru Shikhar.
🪨 Geology
The geology of the Aravalli Range is one of its most remarkable features.
The mountains form part of the Aravalli–Delhi orogenic belt, a northeast–southwest-trending zone of ancient crust in northwestern India. Geological research identifies rocks and tectonic events in this region extending far back into the Precambrian, including Archean basement rocks and major Proterozoic sedimentary, volcanic, metamorphic, intrusive, and deformation events.
Two major geological packages are especially important:
Aravalli Supergroup
The Aravalli Supergroup contains ancient sedimentary and volcanic rocks that were subsequently altered by metamorphism and deformation.
These rocks record the development of basins along very old continental crust and preserve evidence of major changes in the early Indian landmass.
Delhi Supergroup
The younger Delhi Supergroup contains additional sequences of sedimentary and volcanic rocks that were folded, faulted, metamorphosed, and intruded during later tectonic events.
Together, these geological units reveal a history involving continental rifting, basin development, volcanism, compression, metamorphism, mountain building, and erosion.
The present Aravallis are therefore only the surviving remnants of a much older mountain-building system.
Why Are the Aravallis So Low Today?
Age is the key.
Once tectonic uplift declined, enormous spans of geological time allowed weathering and erosion to strip away the mountains. Rivers, temperature changes, wind, chemical weathering, and physical breakdown gradually reduced the landscape.
That helps explain the contrast between the Aravallis and the Himalayas.
The Himalayas are geologically young and remain tectonically active. The Aravallis represent the deeply eroded remains of mountain-building events that occurred vastly earlier in Earth’s history.
⛏️ Minerals & Geological Resources
The Aravalli region is also notable for its mineral deposits.
Its complex geological history created conditions favorable for numerous economically important minerals and ores. Mining districts associated with the greater Aravalli geological belt have produced materials including:
- Copper
- Lead
- Zinc
- Marble
- Granite
- Limestone
- Phosphate
- Building stone
Mining has played a role in the history and economy of Rajasthan for centuries, but quarrying and mineral extraction have also contributed to habitat loss, landscape fragmentation, erosion, and other environmental pressures in parts of the Aravallis.
🌿 Flora & Fauna
Vegetation across the Aravallis changes dramatically with rainfall, elevation, soils, and latitude.
Dryer sections support thorn scrub and dry deciduous vegetation, while comparatively wetter slopes contain more substantial woodland. Rajasthan’s Forest Department describes a transition from tropical thorn forest in the state’s arid regions toward dry deciduous forests in the Aravalli hills.
Common vegetation in different parts of the range includes species of:
- Acacia
- Anogeissus
- Boswellia
- Ziziphus
- Terminalia
- Bamboo
- Thorny shrubs and grasses
Mount Abu is particularly distinctive. Higher elevations and increased rainfall support vegetation unlike much of surrounding Rajasthan, including semi-evergreen elements in some areas.
Wildlife
Despite extensive human settlement and fragmentation, portions of the Aravallis remain important wildlife habitat.
Animals found in different sections of the range can include:
- Indian leopard
- Bengal tiger
- Striped hyena
- Golden jackal
- Sloth bear
- Sambar
- Chital
- Nilgai
- Wild boar
- Langurs
- Numerous reptiles and bird species
Sariska Tiger Reserve in the northern Aravallis is one of the range’s best-known protected landscapes. The Rajasthan Forest Department lists Sariska among the state’s designated tiger reserves.
Habitat corridors through the Aravallis are particularly valuable because wildlife must move between increasingly separated forests, hills, protected areas, and rural landscapes.
💧 Rivers & Watersheds
The Aravallis influence several important drainage systems of northwestern India.
Rivers and tributaries originating in or strongly influenced by the range include parts of the:
- Banas River system
- Luni River system
- Sabarmati River system
- Sahibi River system
- West Banas River system
The direction of drainage varies from one side of the range to the other.
Some streams flow east or southeast toward the Chambal and ultimately the Ganges drainage system, while others flow southwest or west toward the Arabian Sea or into inland drainage basins.
Because much of Rajasthan is semi-arid, the Aravalli hills also have considerable importance for watershed protection and groundwater recharge.
🌵 The Aravallis & the Thar Desert
One of the range’s most important geographic roles is its relationship with the Thar Desert.
The Aravallis lie along the eastern side of much of the desert region. Their northeast–southwest alignment does not form the same type of dramatic rainfall barrier created by ranges oriented perpendicular to prevailing monsoon winds, but the hills still influence local rainfall, soil retention, groundwater, vegetation, and wind movement.
Their forests and scrublands also help stabilize soil and reduce land degradation.
For this reason, loss of vegetation and excessive disturbance in the Aravallis can have consequences far beyond the mountains themselves.
🥾 Hiking & Exploring the Aravalli Range
The Aravallis offer a very different hiking experience from India’s Himalayan regions.
Visitors should expect rocky hills, dry forest, ancient ridges, historic forts, temples, wildlife areas, and panoramic viewpoints rather than glaciers and high alpine terrain.
Guru Shikhar
Guru Shikhar is the most obvious destination for visitors seeking the highest point in the range.
Most of the ascent can be approached by road from Mount Abu, followed by steps to the summit complex. The final climb is short but provides extensive views across the surrounding hills.
Mount Abu Trails
Mount Abu offers numerous walking opportunities through forested hills and granite terrain.
Popular destinations around the hill station include viewpoints, temples, lakes, forest areas, and rocky formations.
Kumbhalgarh
The Aravalli hills surrounding Kumbhalgarh combine hiking scenery with one of Rajasthan’s most impressive historic fort complexes.
The surrounding countryside contains rugged forest, steep hills, villages, and wildlife habitat.
Alwar & Sariska
Northern Rajasthan’s Aravalli hills provide a combination of historic architecture and wildlife viewing.
Sariska is primarily known as a tiger reserve, and access to protected zones is regulated. Travelers should use authorized routes, safaris, and guides.
Delhi Ridge & NCR Aravallis
Farther north, portions of the ancient range survive within and around Delhi and Gurugram.
These low rocky ridges may lack the elevation of Mount Abu, but they are fascinating examples of how an extremely ancient geological landscape survives within one of India’s largest metropolitan regions.
🏔️ Field Guide Tip: The most comfortable hiking season in much of the Aravalli Range is generally from late autumn through winter. Carry more water than you expect to need, especially on exposed trails in Rajasthan. Summer heat can become extreme, and wildlife reserves or forest areas may require permits or authorized guides.
🌤️ Best Time to Visit
For most travelers, October through March provides the most comfortable conditions.
October–November
After the summer monsoon, some sections of the range may retain greener vegetation, while temperatures become increasingly pleasant.
December–February
Winter generally offers the best conditions for hiking, sightseeing, wildlife excursions, forts, and archaeological sites.
Higher areas around Mount Abu can become quite cool at night.
March–June
Temperatures rise rapidly during spring and early summer.
Lower-elevation sections of Rajasthan can become extremely hot, making long exposed hikes uncomfortable or potentially dangerous during the middle of the day.
July–September
The southwest monsoon brings much of the region’s annual rainfall.
The mountains can become surprisingly green during the rainy season, but wet rocks, poor road conditions, flash runoff, thunderstorms, and high humidity can complicate outdoor activities.
🧭 Major Places & Attractions in the Aravallis
Mount Abu
Rajasthan’s famous hill station occupies one of the highest sections of the Aravallis.
Visitors come for cooler temperatures, forest scenery, viewpoints, temples, and access to Guru Shikhar.
Dilwara Temples
Near Mount Abu, the Dilwara Jain temples are celebrated for their extraordinarily detailed marble architecture and carving.
Kumbhalgarh Fort
Set among the western Aravallis, Kumbhalgarh is one of Rajasthan’s most spectacular hill forts and forms part of the UNESCO-listed Hill Forts of Rajasthan.
Udaipur
Udaipur lies amid the southern Rajasthan landscape associated with the Aravalli hills.
Its lakes, palaces, rocky ridges, and surrounding countryside make it one of the best bases for exploring the southern range.
Ajmer
Ajmer lies in a basin surrounded by Aravalli hills and combines mountain scenery with considerable historic and religious importance.
Sariska Tiger Reserve
Situated in the northern Aravallis, Sariska protects forests, rocky hills, valleys, wildlife habitat, and archaeological sites.
Delhi Ridge
The Delhi Ridge represents the northern extension of the Aravalli geological system.
Although much lower than the mountains of Rajasthan, these rocky outcrops are ecologically valuable green spaces within India’s capital region.
🏰 History & Cultural Importance
Humans have interacted with the Aravalli landscape for thousands of years.
The range contains mineral resources, water sources, defensible high ground, fertile valleys, passes, forests, and trade routes. These features helped shape patterns of settlement and political power across Rajasthan and neighboring regions.
Fortifications were built on many commanding hilltops.
Among the most famous are the great forts associated with Rajasthan’s Rajput kingdoms, where natural topography became an essential part of military architecture.
The mountains are also dotted with Hindu and Jain pilgrimage sites.
Guru Shikhar itself has religious importance because of the temple dedicated to Dattatreya near its summit.
The result is a landscape where geology, religion, architecture, warfare, trade, and settlement have been interconnected for centuries.
🌱 Conservation Challenges
Despite their age, the Aravallis are far from indestructible.
Parts of the range face pressure from:
- Quarrying and mining
- Urban expansion
- Road construction
- Deforestation
- Habitat fragmentation
- Illegal dumping
- Groundwater depletion
- Invasive vegetation
- Agricultural expansion
These pressures are particularly visible near rapidly developing urban regions in Haryana and Delhi.
Conservation efforts are important not simply because the mountains are scenic. The range provides wildlife habitat, watersheds, groundwater recharge areas, forest cover, soil stabilization, and green space for densely populated regions.
The environmental importance of the Aravallis remains the subject of active government and judicial attention. In 2026, India’s Ministry of Environment, Forest and Climate Change publicized the work of a Supreme Court-appointed High-Powered Committee examining issues concerning the Aravalli Hills and Ranges across Delhi, Rajasthan, Haryana, and Gujarat.
