The chocolate brand enlisted the assistance of creative agency RPM to execute the event proposition for the annual campaign, which this year included more than 300 trails across National Trust and National Trust for Scotland properties.
For the second year running RPM oversaw all experiential elements of the campaign, along with elements including kit design, production, staffing and digital integration.
It was also involved in the delivery of more than 21 tonnes of chocolate, or 250,000 Cadbury Easter eggs, across the National Trust properties.
Visitor numbers rose by 25% during the 2014 Easter Egg Trails campaign, making it the most successful yet. Information around attendance at this year's campaign is yet to be released.
