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.

We love showing off our beautiful place! You’re invited to visit us throughout the year … to relax, to refresh, to restore, to rejuvenate. There’s a truly peaceful quality to the property as well as an overwhelming beauty that is the Dubuque Arboretum & Botanical Gardens itself. Don’t be surprised when you find yourself coming back again and again! And with no admission fee, it’s an easy choice to make. See you soon!



There is no entrance fee to enjoy the Dubuque Arboretum grounds. (The Arboretum is a non-profit organization supported by memberships, gifts, memorials, and endorsements.)
