Famous for its 70 continuous, thrilling hairpin bends along a steep 26 km climb, this offbeat range remains untouched by commercial tourism and is known for its organic farming, medicinal plants, and the sacred Arapaleeswarar Temple.
It is the ultimate destination for driving enthusiasts seeking a hairpin-bend challenge, visiting ancient forest temples, and trekking to the cascading Agaya Gangai waterfall.
