Apart from snow leopards, which surely must be on every wildlife enthusiast's 'to see' list, the following parks and reserves in India and Sri Lanka offer the very best wildlife sightings for big cats.
Tigers
India is indeed the land of the tiger, with some superb tiger reserves found all the way from the Himalayan foothills to the reserves in the deep south.
Nagarhole near Mysore is a splendid wildlife reserve and one of the finest tiger habitats in Asia. There are some superb lodges and luxury camps here and Nagarhole fits in well with a tour of South India and Kerala.
