The Queen and Prince Philip are to visit St Ives and St Michael's Mount later this month.
The Royal visit will include a walk along St Ives seafront to the RNLI lifeboat station and the Tate gallery.
The party will then travel by car to Marazion and the iconic island in Mount's Bay where they will make shoe prints in soft casts on arrival.
The Queen and Prince Philip were last in west Cornwall two years ago when they visited Penzance and the Isles of Scilly in glorious sunshine.
However, this will be the Royal couple's first visit to St Ives.
A notice sent out by Buckingham Palace today stated that the Royal visitors would arrive at Erth station on Friday, May 17, where they will transfer to a scheduled train to St Ives.
They will be met at St Ives station by lifeboat crews and will unveil a plaque to mark their visit.
They will then proceed to Tate St Ives where they will tour the building, meeting architects, staff and artists.
They will then head to Marazion where they will take the amphibious boat to St Michael's Mount and walk to the castle to take lunch as guests of the St Aubyn family.
After lunch, they will tour the castle and chapel and meet families that live on the Mount before leaving the island and departing from Cornwall.
