The park is a World Heritage Site and a wildlife conservation area of global importance, home to elephants, water buffalo, the endangered swamp deer, tigers, and two-thirds of the world population of Indian one-horned rhinoceroses.

Kate was appropriately dressed for the trip, sporting brown skinny jeans, a white cotton shirt and her trusty Sebago boat flats.

It is a cause close to William’s heart – he has been campaigning for a number of years to protect endangered animals. This visit is intended specifically to focus global attention on conservation.

After their safari tour, the couple will interact with the park’s frontline anti-poaching staff at a place called Dimoli.

They then plan to visit the Centre for Wildlife Rehabilitation and Conservation which provides emergency care and rehab for wild animals that have been injured, displaced or orphaned.

To round off their busy morning, they will visit a centre for treatment of captive elephants named after British conservationist Mark Shand. Mark is the late brother of the Duchess of Cornwall.
