What You'll See

 With over 2,500 plant species and a focus on native Colorado Plateau ecosystems, The Arboretum is an ideal spot to find butterflies and other insects, hummingbirds and song birds, raptors, squirrels, lizards, and more. Take a guided tour to learn more about the critters of the Colorado Plateau. The Arboretum is open daily from April through October, and closed during the winter season.
