The Eastern Ghats are an ancient, discontinuous chain of mountains, hills, plateaus, and forested uplands extending along the eastern side of Peninsular India. Although generally lower and less continuous than the Western Ghats, they form one of India’s most geographically, geologically, and ecologically important mountain regions.
Stretching for more than 1,000 kilometers through eastern and southern India, the Eastern Ghats include rugged summits, deeply eroded valleys, tropical forests, sacred hills, waterfalls, coffee-growing areas, and wildlife reserves. Major rivers—including the Mahanadi, Godavari, Krishna, and Kaveri—cut broad passages through the range on their journey toward the Bay of Bengal.
🏔️ Overview
The Eastern Ghats run roughly parallel to India’s eastern coast, generally between the Deccan Plateau and the coastal plains bordering the Bay of Bengal.
Unlike a single continuous mountain wall, the Eastern Ghats consist of many separated hill groups and regional ranges. River erosion, faulting, weathering, and long geological development have divided the mountains into distinct sections.
The principal Eastern Ghats landscapes occur in:
- Odisha
- Andhra Pradesh
- Tamil Nadu
- Telangana
- Southeastern Karnataka
The range includes some of the most important uplands described in the wider guide to the mountains of India. Its best-known regional groups include the Nallamala Hills, Seshachalam Hills, Palkonda Hills, Velikonda Range, Javadi Hills, Shevaroy Hills, Kolli Hills, Kalrayan Hills, Papi Hills, Biligirirangan Hills, and the high country around Koraput and Araku Valley.
The highest point is generally identified as Jindhagada Peak, which rises to approximately 1,690 meters in Andhra Pradesh. However, mountain databases and geographical references do not always agree on the summit’s name or measurement. Some identify nearby Arma Konda, at approximately 1,680 meters, as the range high point or use the two names interchangeably.

đź“Ť Location and Extent
The Eastern Ghats extend along the eastern margin of the Indian peninsula, inland from the Bay of Bengal.
Their northern landscapes include the Similipal Massif and the highlands of Odisha. From there, the mountain belt continues through the Koraput region and the northern hills of Andhra Pradesh before dividing into numerous central and southern ranges.
Northern Eastern Ghats
The northern section contains many of the range’s highest mountains. Important areas include:
- Similipal Massif
- Mahendragiri Hills
- Koraput highlands
- Maliya Range
- Madugula Konda Range
- Araku Valley
- Galikonda and Jindhagada highlands
This region contains Jindhagada Peak, Arma Konda, Deomali, Gali Konda, Sunkrametta, and Mahendragiri.
The high plateaus and valleys around Koraput and Araku are among the most visually dramatic Eastern Ghats landscapes. Forests, grass-covered ridges, agricultural terraces, coffee plantations, waterfalls, and Indigenous villages occupy the region.
Central Eastern Ghats
In Andhra Pradesh and Telangana, the Eastern Ghats divide into several parallel and intersecting hill systems, including:
- Nallamala Hills
- Lankamala Hills
- Palkonda Hills
- Velikonda Range
- Seshachalam Hills
- Papi Hills
The Nallamala Hills extend through a large forested region surrounding the Krishna River and Srisailam. Much of this landscape is protected within the Nagarjunsagar–Srisailam Tiger Reserve.
The Seshachalam Hills rise farther south near Tirupati. They contain the Tirumala Hills, where natural rock formations, ancient geological exposures, forests, waterfalls, and major pilgrimage sites occur within the same landscape.
Southern Eastern Ghats
The mountains become increasingly divided into separate hill groups across northern and central Tamil Nadu.
Important southern ranges include:
- Javadi Hills
- Shevaroy Hills
- Kalrayan Hills
- Kolli Hills
- Pachamalai Hills
- Chitteri Hills
- Sirumalai Hills
The Shevaroy Hills contain the hill station of Yercaud and rise to approximately 1,620 meters at Solaikaradu. The Kolli Hills are known for forested slopes, agricultural terraces, waterfalls, temples, and a road with numerous hairpin bends.
Toward Karnataka, the Biligirirangan Hills form an important ecological connection between the Eastern and Western Ghats. This corridor allows wildlife to move between the two mountain systems.
đź“Ź Elevation and Highest Peaks
The Eastern Ghats are lower than the Himalayas and the highest sections of the Western Ghats. Much of the landscape lies between approximately 300 and 1,000 meters, although several northern and southern summits exceed 1,500 meters.
Notable Eastern Ghats peaks
| Mountain or high point | Elevation | State |
|---|---|---|
| Jindhagada Peak | Approx. 1,690 m (5,545 ft) | Andhra Pradesh |
| Arma Konda | Approx. 1,680 m (5,512 ft) | Andhra Pradesh |
| Deomali | 1,672 m (5,486 ft) | Odisha |
| Gali Konda | Approx. 1,643 m (5,390 ft) | Andhra Pradesh |
| Solaikaradu | Approx. 1,620 m (5,315 ft) | Tamil Nadu |
| Sunkrametta | Approx. 1,620 m (5,315 ft) | Andhra Pradesh |
| Biligiriranganatha Betta | Approx. 1,552 m (5,091 ft) | Karnataka |
| Mahendragiri | Approx. 1,501 m (4,925 ft) | Odisha |
Peak names, elevations, and mountain boundaries are not completely standardized throughout the Eastern Ghats. Several summits have local names, alternate spellings, or measurements obtained from different mapping systems.
Jindhagada Peak or Arma Konda?
The identity of the Eastern Ghats’ highest point has caused considerable confusion.
The Indian Institute of Science’s Eastern Ghats flora resource lists:
- Jindhagada Peak at approximately 1,690 meters
- Arma Konda at approximately 1,680 meters
Peakbagger, by contrast, lists Arma Konda as the range high point at 1,680 meters. Other publications treat Jindhagada and Arma Konda as alternate names for the same mountain.
Until a universally accepted modern survey resolves the naming and location issue, the most careful description is that Jindhagada Peak is commonly recognized as the highest point at approximately 1,690 meters, while Arma Konda remains an alternative high-point listing.
🪨 Geology
The Eastern Ghats preserve evidence of some of the oldest and most complicated geological events in the Indian subcontinent.
Much of the northern mountain region is associated with the Eastern Ghats Mobile Belt, a zone of intensely metamorphosed rock extending through Odisha and northern Andhra Pradesh. Its rocks were transformed under extreme temperatures and pressures deep within Earth’s crust.
Important rock groups include:
- Charnockite
- Khondalite
- Granulite
- Gneiss
- Granite
- Quartzite
- Metamorphosed sedimentary rocks
The charnockite suite consists largely of high-grade metamorphic and igneous rocks formed under deep-crustal conditions. The khondalite suite includes metamorphosed sedimentary rocks containing minerals such as garnet, sillimanite, quartz, feldspar, and graphite.
Geological evidence connects parts of the Eastern Ghats with ancient continental collisions, crustal reworking, and the formation and breakup of supercontinents such as Rodinia and Gondwana.
However, the geographical Eastern Ghats cover a broader region than the Eastern Ghats Mobile Belt. Southern ranges in Andhra Pradesh and Tamil Nadu include additional geological formations, sedimentary basins, quartzite ridges, granitic uplands, and exposed ancient basement rocks.
The Tirumala Hills contain an especially important feature known as the Eparchaean Unconformity. Here, ancient Archean rocks meet much younger sedimentary formations, representing an enormous gap in Earth’s geological record.
đź’§ Rivers and Waterfalls
The Eastern Ghats are famously discontinuous because several major rivers cross them from west to east.
Mahanadi River
The Mahanadi passes through the northern Eastern Ghats before reaching the coastal plains of Odisha and forming a large delta near the Bay of Bengal.
Its tributaries have cut valleys and gorges through the surrounding highlands.
Godavari River
The Godavari crosses the Eastern Ghats through a dramatic gorge bordered by the Papi Hills. This forested river corridor is one of the most scenic areas in Andhra Pradesh.
Parts of the surrounding landscape are protected within Papikonda National Park.
Krishna River
The Krishna passes through the Nallamala Hills near Srisailam. Its valley separates sections of the central Eastern Ghats and supports reservoirs, forests, wildlife habitats, and pilgrimage sites.
Kaveri River
The Kaveri cuts through the southern hill systems before entering the Tamil Nadu plains. The Biligirirangan and Malai Mahadeshwara hills form an important forested landscape near the river and help connect the Eastern and Western Ghats.
Numerous smaller rivers and seasonal streams originate in the Eastern Ghats. The region also contains waterfalls such as Duduma Falls, Katiki Falls, Talakona Falls, Hogenakkal Falls, and Agaya Gangai Falls.
🌿 Flora and Fauna
The Eastern Ghats support a remarkable variety of habitats created by differences in rainfall, elevation, soil, geology, and latitude.
Vegetation includes:
- Thorn scrub
- Dry deciduous forest
- Moist deciduous forest
- Semi-evergreen forest
- Patches of evergreen forest
- Bamboo forest
- Montane grassland
- High-elevation forest resembling shola vegetation
More than 4,500 flowering plant species have been recorded across the broader Eastern Ghats region. Many have restricted distributions, particularly within isolated hill ranges.
Notable plants include:
- Red sanders
- Beddome’s cycad
- Indian sandalwood
- Teak
- Terminalia species
- Bamboo
- Wild mangoes
- Orchids
- Medicinal plants
Red sanders is especially associated with the southern Eastern Ghats of Andhra Pradesh. Its limited natural range and valuable timber have made illegal harvesting a major conservation concern.
Wildlife found in protected Eastern Ghats landscapes includes:
- Bengal tiger
- Asian elephant
- Indian leopard
- Dhole
- Sloth bear
- Gaur
- Sambar
- Chital
- Four-horned antelope
- Wild boar
- Indian giant squirrel
- Numerous reptiles and birds
Rare animals associated with parts of the region include Jerdon’s courser and the Indian golden gecko.
The Eastern Ghats are not separately classified as one of the world’s formal biodiversity hotspots. Nevertheless, their isolated forests contain significant plant diversity, localized species, wildlife corridors, and important populations of threatened animals.
Protected areas include:
- Similipal National Park
- Papikonda National Park
- Sri Venkateswara National Park
- Nagarjunsagar–Srisailam Tiger Reserve
- Seshachalam Biosphere Reserve
- Biligiri Ranganatha Temple Tiger Reserve
- Kambalakonda Wildlife Sanctuary
- Kaundinya Wildlife Sanctuary
Habitat fragmentation, mining, road construction, dams, agricultural expansion, forest fires, invasive species, and illegal timber harvesting remain significant conservation challenges.
🥾 Hiking and Climbing Routes
The Eastern Ghats do not contain a single continuous long-distance trail. Hiking is generally organized around individual peaks, hill stations, forest reserves, waterfalls, and pilgrimage areas.
Deomali
Deomali is Odisha’s highest mountain and one of the Eastern Ghats’ most accessible high summits.
Roads reach the upper mountain, while walking routes cross open grassland and rolling ridges. The summit area offers wide views across the Koraput highlands.
Conditions can be foggy, wet, and windy during the monsoon.
Jindhagada and Arma Konda
The highest mountains of the northern Andhra Pradesh Eastern Ghats lie in remote forested and tribal areas.
Access is less developed than at Deomali, and routes may involve unmarked roads, village tracks, dense vegetation, and unclear summit boundaries. Local guides and advance planning are strongly recommended.
Araku Valley and Gali Konda
Araku Valley provides access to viewpoints, coffee-growing areas, waterfalls, caves, and forest trails.
Gali Konda is one of the region’s highest summits, although hiking access and route information can vary. Travelers should confirm local conditions rather than relying entirely on online trail maps.
Mahendragiri
Mahendragiri combines mountain scenery with major cultural and religious importance.
Roads and pilgrimage paths approach the summit area, where ancient temples stand among grassland, rocky slopes, and forest.
Nallamala Hills
The Nallamala Hills contain large, remote forests and wildlife habitats. Some visitor areas can be explored from Srisailam, but entry into protected forest sections may require permits or official guides.
Wildlife awareness is essential because the landscape supports tigers, leopards, sloth bears, and other large animals.
Yercaud and the Shevaroy Hills
Yercaud offers some of the most accessible walking routes in the southern Eastern Ghats.
Visitors can explore viewpoints, forest paths, coffee estates, lakes, gardens, and the high country near Servarayan Temple and Solaikaradu.
Kolli Hills
The Kolli Hills are popular for waterfall walks, viewpoints, temples, forest roads, and agricultural landscapes.
The route to Agaya Gangai Falls involves a long stone stairway and can be tiring in hot or humid weather.
Biligirirangan Hills
The Biligirirangan Hills contain forest trails and wildlife-viewing opportunities within a protected tiger reserve.
Access regulations can change, and some routes require authorization or accompaniment by approved guides.
🏔️ Field Guide Tip: The Eastern Ghats cover an enormous area, and trail conditions vary from developed hill-station paths to remote forest routes. Confirm permits, road access, weather, and guide requirements locally before beginning a hike.
🌤️ Best Time to Visit
The best time to explore most of the Eastern Ghats is from October through February, when temperatures are generally cooler and outdoor conditions are more comfortable.
October to December
The post-monsoon landscape is often at its greenest. Waterfalls flow strongly, forests are lush, and views can be dramatic.
Roads and trails may still be muddy or slippery, particularly after heavy rain.
January and February
These are usually the most comfortable months for trekking and sightseeing. Skies tend to be clearer, humidity is lower, and conditions are cooler at higher elevations.
March to May
Summer can be extremely hot at lower elevations. Hill stations such as Yercaud and Araku may remain cooler than the surrounding plains, but exposed trails can still become uncomfortable.
June to September
The southwest monsoon brings rain to many northern and central areas. Landslides, slippery trails, flooding, poor visibility, and difficult road conditions are possible.
Parts of Tamil Nadu also receive substantial rainfall during the northeast monsoon between October and December.
