Camilla looked to be in high spirits as she arrived at Mevagissey Harbour with the Prince of Wales, where she tucked into some ice cream and met with local residents.
The royal couple also enjoyed an afternoon picnic in celebration of the 10th anniversary of the Eden Project's 'Big Lunch', an organisation of which the Duchess is patron.
The Big Lunch is a National Lottery-funded project which aims to bring neighbours and local communities together.
On Sunday, Camilla surprised the England cricket team with a very special gift during their World Cup final against New Zealand.
It's a longstanding tradition for fans to send baked treats to BBC radio commentators covering the match, but this year the team received a right royal shock when the Duchess of Cornwall sent a cake depicting the World Cup trophy alongside Endland and New Zealand batting helmets, captains Eoin Morgan and Kane Williamson, a cricket ball and two bails.
It came with a note from Clarence House which read: “I hope this cake will bowl you over! With my best wishes, Camilla.”
