The Detroit Zoological Society (DZS) will host GreenFest at the Detroit Zoo and virtually on our Facebook page Thursday, April 22, 2021, 9 a.m. to 3 p.m. This event, presented by DTE, is dedicated to celebrating Earth Day and engaging the community in environmental stewardship.

GreenFest will look a little different than in past years due to the pandemic. Guests will be encouraged to follow us on social media for green lessons and also check out our virtual Sustainability Trek – an interactive mobile map system – offering a guided sustainability tour highlighting the DZS’s anaerobic digester, permeable pavement visitor pathways, rain gardens, solar energy system and other sustainability initiatives. To launch the trek, visit

The first 1,000 visitors on April 22 will also receive a tree seedling and pollinator garden seeds to plant at home!
