It is said that Sairandhri discovered the Silent Valley forests in Palakkad. She was so struck by its beauty that her legend made the area famous as Sairandhrivanam or simply called Sairandhri's forest.
In the Hindu legend, Sairandhri is Draupadi, the polyandrous wife of the five Pandavas, who disguised herself as Sairandhri, queen Sudeshna's assistant, while they were in exile. The Pandavas, deprived of their kingdom, set out on a 13-year exile. They wandered south, into what is now Kerala, until one day they came upon a magical valley where rolling grasslands met wooded ravines, a deep green river bubbled its course through impenetrable forest, where at dawn and twilight the tiger and elephant would drink together at the water's edge, where all was harmonious and man unknown.
