Virudhunagar District is landlocked on all sides with no direct access to the sea. It is bound on the north by Madurai, on the north-east by Sivaganga, on the east by Ramanathapuram and on the south by Tirunelveli and Tuticorin districts.
Physiographically it consists of two distinct regions. The eastern slopes of the Western Ghats in Srivilliputtur and Rajapalayam taluks and the black soil plains of Sivakasi, Virudhunagar, Sattur, Aruppukkottai, Tiruchili and Kariapatti. The average height of the hills of the eastern slopes of the Western Ghats is 1500m, though a few peaks rise to 1700m. The highest peaks are Peyimalai Mottai and Kottamalai. The foothills have rich loamy soil with good vegetation cover. The plains with black cotton soil (locally known as karisal) have underlying cal carious formations.
