Welcome to the campus tree tour registration page! These tours are free, but these registrations are requested to give us an idea how many people will be attending. Note that this registration page includes tours both at the University of Washington and Western Washington University (please be sure to check to ensure you know where your tour is located)!

To learn more about tour times, dates, and starting locations at the University of Washington, visit the Guided Tree Tours Page of the Campus Tree Tours website. The Campus Tree Tours website also includes numerous self-guided tours!

To learn more about the location and times of tour at the Western Washington University Campus, visit the Raven’s Roots Naturalist School Short Courses Page.

The campus tree tours are guided on a voluntary basis by Theodore Hoss, an instructor at the Raven’s Roots Naturalist School. If you want to take some time to look around at some of his other programs, you can do so on this website here.


These Free Guided Tree Walks are offered by a volunteer guide, who also maintains the Campus Tree Tour website. If you would like to leave a tip to help with travel costs and continued maintenance of the tour, it is always so appreciated!
