We Offer Free Guided, Self-Guided and Virtual Tree Tours!

We offer guided trees tours throughout the academic school year (usually Sept. - May). There are printed self-guided, and virtual tours available as well. See our tree tours page for more information. 


We impact Arizona and a growing global community as we exercise the University's Land Grant mandate to serve and inspire through public outreach. The University of Arizona Campus Arboretum provides a wealth of knowledge through its online resources, statewide programs to audiences of all ages and free tree tours and events offered to Tucson visitors and local residents.

The Tree Stewards Program  is run through a partnership with the Pima County Cooperative Extension Master Gardeners. Master Gardeners complete workshops and training to qualify as tree educators. They then volunteer as docents for tours and serve as trainers for students interested in leading tours.

Phenology Trails and Training Program is a partnership with the National Phenology Network. You can join thousands of other individuals who are providing valuable observations that scientists, educators, policy makers, and resource managers are using to understand how plants and animals are responding to climate change and other environmental changes. Register for Nature's Notebook on the NPN website and search for UA campus sites including Old Main and the Krutch Garden.
