Kasaragod district lies between 110 18’ and 120 48` north latitudes and between 740 52` and 750 26` east longitudes. The Western Ghats which run parallel to the sea marks off the district from the adjoining areas outside the state and constitute an almost continuous mountain wall on the eastern side. The Ghats dominate the topography. The coastline is fringed with low cliffs alternating with stretches of sand. A few miles to the interior, the scene changes and the sand level rises towards the barrier of the Ghats and transforms into low pink laterite hills interspersed with paddy fields and coconut gardens.
Based on the physical features the district falls into three natural divisions – the low land bordering the sea, the midland consisting of the undulating country and the forest clad highland on the extreme east.
