Manimuthar River originates on the eastern slopes of Western Ghats in Tirunelveli District of the state of Tamil Nadu in southern India.
The river begins in the dense forest on a mountain peak 1,300 metres (4,300 ft) above sea level in Ex-Singampatti Zamindari, Ambasamudram taluk and flows 9 kilometres (6 mi) though small cataracts until it reaches the Tambaraparani River near Kallidaikurichi.

Located on top of the Manimuthar Dam and the Manimuthar Water Falls, the Manjolai area comprises tea plantations, small settlements around the tea plantations, Upper Kodaiyar Dam and a windy viewpoint called Kuthiravetti.
