History & Nature

Experience the beauty of Arizona’s oldest and largest botanical garden, dating back to the 1920s. It’s named for mining magnate Colonel Willian Boyce Thompson, who discovered the importance of plants as a source of food, clothing and shelter during his time in Russia on a Red Cross mercy mission.

The enormous Picketpost Mountain serves as a backdrop as you approach the Arboretum. Once inside, don’t miss the Cactus Garden featuring bizarre shapes in cacti, or relax under shaded trees in Queen Creek Canyon. 

To stimulate your mind, visit the Smith Interpretive Center featuring greenhouses that showcase rare cacti and succulents. Stop by the Demonstration Gardens to learn which low water-demanding plants you could incorporate in your own garden at home. The Main Trail and High Trail surrounding the Arboretum offer views of picture-perfect vistas.
