Their visit to Nottingham comes four days after Harry and Markle announced their engagement.
The city was overrun with crowds of people, members of the press and photographers ahead of the couple's visit.
Mary Cooper, 60, who had been waiting to see the prince and his bride-to-be since before 9am, said: "I think it's absolutely wonderful that both he and his brother have found happiness".

Markle, who has been a campaigner for several causes including work as a U.N women's advocate, is to give up her previous charity roles as she begins life in Britain's royal family, Harry's spokesman said on Tuesday.
The Queen has granted permission for the pair to Wednesday inside St George's Chapel at Windsor Castle but Meghan - a protestant who went to a catholic high school - will be both baptised and confirmed, before the big day to be ready for the religious ceremony.
Alison shouted "congratulations" as Prince Harry walked past, as host Ruth Langsford encouraged her to get his attention.
"This is good. I'm excited to have some Americans in the royal family", US student Mark Arnold, who is now studying at Nottingham University, told Reuters.
