The Dubuque Arboretum and Botanical Gardens (60 acres) are an arboretum and botanical gardens established in 1980 and located at 3800 Arboretum Drive, Dubuque, Iowa. Admission is free and the grounds are open year round from down to dusk. The arboretum was created and is maintained by all volunteers.
