Tamiraparani—the only perennial river in Tamil Nadu—originates in the Pothigai Hills in Tirunelveli District. “Trails of Tamiraparani” is an attempt to capture the myriad hues of the landscape, the travails of the past, its glorious heritage, and the prosperity of the region. The book comprises four chapters—Ainthinai, Panpadu, Varalaru, and Vazhviyal as enshrined in the ancient Tamil Sangam literature. Ainthinai (landscapes), captures the five vivid landscapes of Tirunelveli from the mountains to the shores, while Panpadu (culture) reminisces the symbols of past glory. Varalaru (history) offers a glimpse into the transition from Tinnevelly to Tirunelveli and Vazhviyal is a colorful narrative of people, culture, and livelihoods.
