Agaya Gangai Upper Steps & Arapaleeswarar Trail
"The 1,200 Cliff Steps, Sacred Aiyaru Chasm & Siddhar Lore of Kolli Malai"
Agaya Gangai Upper Steps is the famous 1,200 stone steps trailhead and upper cliff viewpoint overlooking the magnificent 90-meter (300 feet) Agaya Gangai waterfall on the Aiyaru River beside the historic Arapaleeswarar Temple in Kolli Hills, Namakkal District, Tamil Nadu. Situated 45 km from Namakkal and 90 km from Salem, it is celebrated for its challenging cliff staircase trek, ancient Tamil Siddhar cave lore, and authentic Kongu Nadu gastronomy.
1. Overview, Topography & Identity
Perched atop the sheer vertical charnockite amphitheater canyon where the sacred Aiyaru River plunges 90 vertical meters (300 feet) into a mist-shrouded green chasm, Agaya Gangai Upper Steps marks the legendary starting point of Kolli Hills' most exhilarating pilgrimage trek. Located directly beside the ancient 1st-century CE Arapaleeswarar Temple in Valavanthinadu, the trail descends 1,200 steep stone steps cut into the granite cliffside amidst dense medicinal herb forests and banana plantations in the Eastern Ghats.
The Aiyaru Sacred Mountain River
Originating from the central highland plateau of Kolli Malai near Solakkadu, the Aiyaru River flows past the temple compound before suddenly hurtling off the horizontal escarpment lip into the deep valley gorge.
Masila Falls & Seekuparai Viewpoint
Across the mountain ridge lie **Masila Falls (40m)**, a serene family cascade, and **Seekuparai Viewpoint**, a cliff promontory offering sweeping vistas across the plains of Namakkal and Trichy.
Selur Viewpoint & Kolli Pavai (Ettukai Amman) Temple
At the highest southern rim of Kolli Hills lies **Selur Viewpoint**, known for banana valley panoramas, while near the forest borders stands the mysterious shrine of **Kolli Pavai (Ettukai Amman)**, the ancient eight-handed guardian deity of Kolli Malai described in classical Sangam literature.
The runoff feeds into the Aiyaru River network, flowing southward to merge with the Kaveri River near Mohanur in the Tamil Nadu plains.
2. Geology: Eastern Ghats Charnockite Escarpment & Aiyaru Gorge Infilling
The geological bedrock belongs to the Proterozoic Southern Granulite Mobile Belt, dominated by hard hypersthene-bearing charnockites and hornblende gneisses.
90-Meter Sheer Fault-Scarp Plunge
Tectonic block faulting along the Kolli Hills perimeter created the vertical cliff wall. Millions of years of fluvial plunge pool cavitation have carved a colossal 300-foot-deep amphitheater canyon flanked by vertical rock walls.
