A Passage Through India has seen actress Caroline Quentin (correct) embark on an epic journey through one of the world's most remarkable and diverse countries.

Experiencing Indian society at every level, staying with local families and meeting everyone from Maharajas to mahouts, she has gained first-hand experience of unique elements of the country's richly diverse culture along the way.

In this final episode, Caroline completes her journey by travelling from the city of Mysore to Indian's southern most tip, where three seas collide - the Bay of Bengal, the Arabian Sea and the Indian Ocean.

On the way she has close encounters with poisonous snakes and baby elephants, meets a healer with an international reputation and chats to Mysore's answer to Willy Wonka.

As she reaches the end of her trip, Caroline reflects on how India has influenced her.
