The Carndonagh Christmas Tree Committee is responsible for annual maintenance of the festive tree in The Diamond. They are a voluntary group of people who give their time to making the town look festive every year. The preparations begin in November evenings ensuring the town and its approaches will look their best over the festive season. A number of events take place around the Christmas period and the Christmas tree Committee depend on the support of the local community. The Christmas tree lighting takes place on the first Sunday of December which includes carol singing and a visit from Santa.
