Joanna ends her 5,000 mile journey in the place where she was born, Srinagar in Kashmir. She starts off in the Ranthambhore National Park, where she hopes to spot a tiger in the wild. Meeting tiger conservationist Belinda Wright, Joanna witnesses the work of local NGO Tiger Watch, who are attempting to break a cycle of poaching and poverty through education. Home to over 18 million people, Delhi is a city of stark contrasts. The extreme differences are obvious when Joanna visits a homeless community - where 10,000 men live under a flyover - and visits the modern part of the city where she has a go at working in a hi-tech call centre. The final leg of her journey takes her north from Delhi to Dharamsala, where she is granted a private audience with His Holiness the Dalai Lama. Joanna concludes her trip with a stay on a houseboat in Srinagar, as her parents did on honeymoon in 1941.
