The Countryfile team celebrate the festive season with a woodland Christmas at Westonbirt Arboretum in Gloucestershire, lighting up a mile-long stretch of enchanted woodland with glitter balls, lasers, meteorite lights and bubbles full of smoke. Julia Bradbury acts as lighting apprentice for the day, learning from the experts how to create a magical festive display. Matt Baker learns about the history of the ancient woodland, and how the Forestry Commission keep the trees happy and healthy. John Craven is with the volunteers who run the hedgehog hospitals. They are overflowing at this time of year with juvenile hedgehogs who need fattening up before they go into hibernation. Tom Heap finds out how farmers capitalise on Christmas. Some sell Christmas trees and mistletoe, while others have reindeers for Christmas events. Adam Henson is on his farm settling his animals in for the Christmas period, with his father and his son lending a hand. He also visits his local agricultural college in Cirencester, seeing how the students there prepare for their break and tracking down the choir for a few carols. Ellie Harrison is with Michelin award-winning chef Tom Kerridge as they cook up something tasty with partridge and pears in the woodland. The whole team come together at the end of the programme for the big light switch on and some festive cheer.
