Stanhill Farm

Kent is choc-a-block with farms, including Stanhill Farm, near London. It's run by two brothers, Max and Toby, who have turned 150 acres into a site for growing more than 30 varieties of fruits and vegetables. You can pick to your heart's content and then swing by their Berries & Beans Café to refuel; they serve hot drinks and snacks like toasties and cakes. There's also a Maize Maze, which is perfect for the little ones.
