Everyone is invited to take part in the event, taking place in the glorious surroundings of Bantock House Museum and Park on Saturday 9 May, 2015, from 12pm to 2pm.
Visitors are encouraged to show their support for Fairtrade by bringing along their own picnics - making sure they contain at least one Fairtrade item.
Bantock House Museum will also be open to the public, with families invited to try out a range of fun indoor and outdoor games, while the popular Courtyard Café will be serving a wide range of homemade food, drinks, ice cream and Fairtrade snacks from 9am to 5pm.
Ann Bickley from Wolverhampton Fairtrade Partnership said: "Wolverhampton was first awarded Fairtrade status by the Fairtrade Foundation in 2004, and we've endeavoured to uphold that honour ever since, working with the local community as well as with national and international organisations to promote Fairtrade.
"Our aim is to raise awareness of Fairtrade products and encourage residents, visitors and businesses to switch to Fairtrade wherever possible. By choosing Fairtrade products, people can help to make a big difference to the lives of farmers in the developing world by ensuring they get a fair price for their produce.
"We're hoping that families will get a flavour of the wide range of Fairtrade products that are available by joining us at the picnic on 9 May, and enjoying a great day out at Bantock House Museum and Park at the same time."
Bantock House Museum and Park is on Finchfield Road. For more details, please call 01902 552195.
