Amy, who was accompanied by new husband Blake Fielder, is Tuesday's sell-out headline act. Other talents appearing at the Cornish Biomes include Lily Allen and the Pet Shop Boys. James Morrison and Rufus Wainwright have already entertained the crowds.
While the 23-year-old's in town she may want to take time to explore the Eden Project with its incredible collection of horticultural wonders. The Humid Tropics Biome reproduces the sights and smells of the rainforest in the world's largest greenhouse, while the Warm Temperature dome, with its orange and lemon trees and olive groves, transports visitors to South Africa and California.
Cornwall, on England's south west coast, is of course a favourite spot not only for surfers who flock to the beaches of Newquay but for the rich, famous and royal - including Princes William and Harry, who hang out in trendy Rock. Pierce Brosnan, Claudia Schiffer and Kate Winslet, meanwhile, have all stayed at the exclusive Tresanton hotel in pretty, harbourside St Mawes.
And celebrity chef Rick Stein has set up camp in the charming fishing village of Padstow where he runs several seafood eateries. As well as stunning beaches and fabulous food, Cornwall also boasts historic landmarks such as the medieval Tintagel Castle associated with the legend of King Arthur.
