SOUTH INDIA IS WHERE the great Dravidian kingdoms were established, and anyone interested in ancient history and grand temples must visit Tamil Nadu or Karnataka. Nothing can really prepare a visitor for the temples, where images of the quiet bustle of the vast halls, the huge gopurams completely covered by colored sculptures of gods and goddesses, the sight of bare feet walking across cool slabs, the heady smell of incense and the chime of the temple bell rung by priests and the faithful leave entrancing impressions. Enjoy the lush, green tropical landscapes of coconut groves, paddy fields and placid backwaters that make up the Kerala coastline.
