See Prince William and Kate's royal tour itinerary of India and Bhutan

The Duke and Duchess of Cambridge will embark on what is perhaps their most colourful royal tour to date – a seven-day trip to India and Bhutan this spring. William and Kate will undertake the official visit from 10 to 16 April at the request of Her Majesty's government, the week before the Queen celebrates her milestone 90th birthday.

It will be the first time the Duke and Duchess have visited either country and they are "very much looking forward" to the tour, a Kensington Palace statement revealed. "The Duke and Duchess cannot wait to meet the people of India and Bhutan," it added.

In India – a country the Queen has visited several times before – William and Kate will pay respect to the historical relationship between Britain and India, but will also focus on understanding India as it is today and will be throughout the 21st century.

As for Bhutan, the royals will meet their Majesties the King and Queen, who have been dubbed the "William and Kate" of the Himalayas.

The couple will then head to Oval Maidan, a large public park that is home to cricket pitches where they will watch a young person's cricket match and meet representatives and beneficiaries of three charities – Magic Bus, Doorstep, and India's Childline – and play with children from nearby slums. There may be a few surprises during this engagement!

Two engagements have been scheduled for the morning and will be confirmed nearer the time.

Kaziranga is a World Heritage Site and a wildlife conservation site of great global importance, home to elephants, water buffalo, bird species, the endangered swamp deer, tigers and one-horned rhinoceroses.

They will arrive in the evening and as their visit coincides with the Bohag Bihu festival, the celebration of the Assamese New Year, William and Kate will meet local people and see dance and musical performances around a campfire.

The following morning the couple will take part in an open-air drive around the National Park itself. They will be welcomed by local people and park staff and later meet rangers inside Kaziranga.

William will use this opportunity to speak about rhino poaching and the lies that surround the Indian rhino horn that is being sold by traffickers.

After the tour of the park, the Duke and Duchess will meet local people in a village. Details will be announced later.

In the afternoon, they will visit the Centre for Wildlife Rehabilitation and Conservation, which provides emergency care and rehabilitation to wild animals that have been injured, displaced, or orphaned.

William and Kate will also meet young filmmakers who are members of Green Hub, a project that teaches film-making as a vocational skill to young people across North-East India.

They will then visit the Kaziranga Discovery Centre built by Elephant Family, the charity founded by Mark Shand, late brother of The Duchess of Cornwall. The couple will put the finishing touches on an elephant sculpture to officially mark the "call for artists" for India's elephant parade.

Day Five –Thursday 14 April – Bhutan

William and Kate will hike for five to six hours to Paro Taktsang, the Tiger's Nest monastery which dates to 1692.

Back in Thimphu that evening, the couple will attend a reception for British nationals in Bhutan and Bhutanese people with strong links to the UK.
