Western Ghats

The Siruvani hills form part of the Western Ghats south of the Nilgiris and north of the Palakkad Gap. Forested slopes and high grasslands rise above the low passage that links the Malabar coast with the inland plains around Coimbatore. Streams from these hills feed the Siruvani River and its neighbouring watersheds. The mountains receive the southwest monsoon, while the broad gap offers an unusually accessible route through a range otherwise marked by steep ridges and deep valleys.
