He has begun the visit by calling on President Uhuru Kenyatta at State House.
The Duke spoke of his deep personal affection for Kenya, the scene of his engagement to the Duchess of Cambridge, Kate Middleton.
The two discussed the deep ties between the United Kingdom and Kenya across a broad range of topics, including defence and security – where the Duke paid tribute to Kenya’s role in combating terrorism in Somalia – and conservation.
The Duke, who is President of United For Wildlife, will use his time in Kenya to see first-hand some of the longstanding conservation and anti-poaching initiatives taking place, which are supported by Tusk Trust, the charity of which he is Royal Patron.
He will witness vets at work in the field as they fit radio tracking collars to elephants to help with research and conservation.
William will also spend time with a team of highly trained rangers in Lewa Conservancy, to learn about their work protecting one of Africa’s significant rhino populations from poaching.
The remainder of this short visit to the country will be private.
