King Charles III and Queen Camilla will visit Guernsey on 16 July.
The royal programme will include meeting local deputies and a centuries-old ceremony of homage to His Majesty, held outdoors on the St Peter Port seafront where islanders can come to watch the event.
The King and Queen will then head to Crown Pier to learn more about the island’s environment, heritage and traditions.
The showcase will include the ongoing work to promote Guernesiaise, local food production, and biodiversity initiatives.
Their Majesties last visited the Bailiwick in July 2012.
The Bailiff of Guernsey, Sir Richard McMahon, said “It will be a great privilege to welcome Their Majesties to the Bailiwick for the first time as King and Queen; the year after their Coronation.”
“Their visit this summer shows just how special the relationship between the Crown and the Islands is.”
Part of the visit is to demonstrate the bailiwick’s commitment to supporting biodiversity, sustainability and combatting climate change.
Chief Minister Lyndon Trott said: “We are looking forward to showcasing our initiatives to support those efforts and promote sustainability across a range of sectors.”
The States said the King and Queen are not able to go to Alderney and Sark due to “time restraints”.
Representatives from those islands will be present, Lt Gen Richard Cripwell CB CBE said: “We look forward to welcoming representatives from Alderney and Sark to Guernsey on the day of the visit.”
Their Majesties are due to visit Jersey the day before on 15 July.
