About the Dubuque Arboretum

Established in 1980, the Dubuque Arboretum & Botanical Gardens in Marshall Park is a living museum developed by volunteers. Their work is a labor of love for all who visit The Gardens as well as a symbol of devotion for the growing things of the earth.

You’re invited to visit us soon!
