First Saturday Tours are a wonderful way to introduce yourself to the Arboretum or to deepen your understanding of the Arboretum's plant collections. Each tour is a little different depending on the time of year, the interests of the tour guide and the people who join in. You might learn more about the birds and mammals that make this land their home or about the amazing physical adaptations that plants have evolved to better deal with extreme weather and climate conditions.

Tours given on the 1st Saturday of each month - at 11am

Tour is FREE with paid admission!

Meet your tour guide(s) at the entrance to the Visitor Parking lot. Walks will be about one hour.

Tours cancelled if the weather is unsuitable.
