Kolli Hills Travel Guide

Mythological Guardians: The Legend of Kolli Pavai & King Valvil Ori

Rising like an impenetrable green fortress above the agricultural plains of Namakkal district in central Tamil Nadu, the Kolli Hills (known historically as *Kolli Malai*) reach an elevation of 1,300 metres across an isolated 280-square-kilometre block of the Eastern Ghats. The ominous name *Kolli Malai* translates from classical Tamil as the "Mountain of Death." Ancient Sangam literature recounts that the mountain was guarded by a terrifying celestial maiden or protective goddess named *Kolli Pavai* (or *Ettukkai Amman*—the Eight-Armed Goddess). Sages and ascetics who meditated in these forested ranges sculpted her image into the rocky peak to ward off demons and unwelcome intruders who sought to desecrate the sacred herbal groves; any trespasser harboring evil intentions was struck down by her divine laughter.

In historical reality, Kolli Hills was the sovereign mountain kingdom of King Valvil Ori (c. 2nd century CE), celebrated in Sangam poetry as one of the *Kadai Ezhu Vallalgal* (the Seven Great Philanthropic Chieftains of ancient Tamilakam). Ori was celebrated as a peerless archer whose bowmanship was legendary: a single arrow shot from his bow was sung to have pierced successively an elephant, a tiger, a deer, a wild boar, and an iguana before burying itself deep in the earth. A fearless warrior yet deeply compassionate patron of bards and artists, Ori’s annual festival (*Valvil Ori Vizha*) is celebrated every August with traditional archery contests and folk dances.

The mountains are also revered as a primary sanctuary of the Tamil Siddha tradition. Great alchemists and spiritual masters, including Sage Agastya, Bogar, and Korakkar, are believed to have resided in the secret subterranean caverns of Kolli Hills, studying the miraculous rejuvenating properties of wild medicinal herbs and performing penances that sanctify the rocky slopes to this day.

The 70 Hairpin Bends: Engineering the Serpentine Ghat

For motorsport enthusiasts and adventure road-trippers across India, the primary draw of Kolli Hills is its astonishing mountain approach road. Originating at Karavalli village in the foothills, the road climbs twenty-six kilometres up the steep western escarpment to Semmedu, negotiating an incredible, record-breaking sequence of seventy continuous, consecutively numbered hairpin bends.

Unlike modern multi-lane mountain highways, the Kolli Hills Ghat Road remains an intimate, narrow ribbon of asphalt clinging precariously to vertical granite cliffs. Each hairpin bend presents a sharp 180-degree hairpin turn flanked by sheer stone walls on the inside and dizzying vertical drops into the valley on the outside. As travelers ascend higher through the seventy bends, the sweltering heat of the Namakkal plains rapidly gives way to refreshing mountain breezes and billowing clouds of mist.

Along the route, several designated scenic pull-offs—such as the *Karavalli Viewpoint* at the 35th bend and *Seekuparai* near the summit—offer breathtaking vistas where travelers can look back down upon the dizzying, switchback coils of the road snaking through the forested mountain valleys below.

Agaya Gangai Waterfalls: The Heavenly Torrent of the Aiyaru River

The supreme natural spectacle of Kolli Hills is *Agaya Gangai Waterfalls* (meaning "the Ganges of the Sky"). Fed by the mountain rills of the sacred Aiyaru River, this monumental cataract plunges over 300 feet (92 metres) down a vertical amphitheater of sheer black granite cliffs into a deep, foaming emerald pool hidden within a steep forested canyon.

Reaching the base of the falls is an unforgettable physical adventure. Visitors must descend a grueling, near-vertical flight of 1,050 stone and concrete steps constructed down the face of the canyon wall. As one nears the canyon floor, the thunderous roar of the waterfall reverberates through the valley, and a perpetual cloud of cool, pulverized water spray envelops the rocks, coating everything in moss and moisture.

Standing at the base of the roaring torrent, surrounded by towering vertical rock buttresses and prehistoric tree ferns, travelers feel the immense kinetic power of nature. Local tradition holds that bathing in the mineral-rich waters of Agaya Gangai possesses miraculous therapeutic properties, having filtered through miles of wild medicinal roots and herbs high in the mountain catchment.

Arulmigu Arapaleeswarar Temple: Sangam Sanctuary of the Sacred Fish

Perched at the edge of the gorge directly above the trail leading down to Agaya Gangai sits the ancient *Arulmigu Arapaleeswarar Temple*, dedicated to Lord Shiva. Mentioned in the Sangam classical text *Natrinai* and praised in the devotional hymns of the Nayanmar saints, this temple is believed to date back over two thousand years, having received substantial stone endowments from the Chera kings, Chola emperors, and the Vijayanagara rulers.

The presiding deity is worshipped as Arapaleeswarar, accompanied by his consort, Goddess Thayammai (Aram Valartha Nayaki). Within the temple precincts flows the sacred Panchanathi (Aiyaru) stream, forming a tranquil stepped stone tank filled with sacred river fish. A sacred tradition unique to this temple forbids any fishing or harm to these aquatic creatures; devotees feed them puffed rice and sweet offerings.

According to a famous sthala purana, a temple priest was once miraculously shown that even if these sacred fish were caught, sliced, and cooked, the power of Lord Arapaleeswarar would instantly bring them back to life and return them swimming happily to the holy waters—giving rise to the deity’s popular Tamil title *Meenukku Uyir Thandha Arapaleeswarar* ("the Lord who gave life back to the fish").

Living Herbal Wealth, Mountain Honey & GI-Tagged Pineapples

Kolli Hills is celebrated as one of the richest botanical medicine repositories in the Western and Eastern Ghats. The tribal Malayali community, who comprise the majority of the mountain’s inhabitants, possess an unbroken oral pharmacopoeia of traditional *Nattu Vaidyam* and Siddha herbalism, collecting wild roots, barks, leaves, and resins to treat a wide array of human ailments.

Visitors to Semmedu market can explore herbal dispensaries offering authentic preparations: *Thuthuvalai* (for respiratory wellness), *Mudakathan* (for joint mobility), *Sirukurinjan* (the miraculous "sugar-destroyer" herb *Gymnema sylvestre*), and pure forest wild honey collected from cliff colonies of rock bees (*Apis dorsata*). The Tamil Nadu Government maintains an expansive *Medicinal Plants Conservation Area* (MPCA) here to protect rare endangered flora from illegal commercial exploitation.

Kolli Hills is also the undisputed pineapple capital of Tamil Nadu. The unique combination of volcanic red soils, mountain elevation, and abundant sunshine produces exceptionally sweet, low-acidity pineapples (*Kew* and *Mauritius* varieties) cultivated across thousands of terrace farms. Freshly harvested pineapples, organic black pepper, aromatic mountain coffee, and delicious hill bananas (*Nadu Pazham*) are sold along every mountain road.

By road, smooth four-lane national highways connect Chennai (360 km northeast via Villupuram and Attur) and Bengaluru (260 km northwest via Hosur and Salem) to the base at Karavalli, from which the 70 hairpin bends climb up to the central plateau town of Semmedu.

Other scenic highlights atop Kolli Hills include the *Seekuparai Viewpoint*, the *Selur Viewpoint* (offering vistas of the southern Kaveri basin), the serene *Solakkadu botanical park*, and the historic *Masila Falls* (a gentle, accessible family-friendly cascade).
