Surrounded by the Saguaro National Park, this gem of a museum helps explain and interpret the incredible diversity of the flora and fauna of the Sonoran desert. It is one thing to admire the fascinating saguaro cactus, it is another to visit the museum and find out all the wonderful things there are to know about it. I've been here numerous times over the years, and on this visit, we saw some new exhibits, such as a small but interesting aquarium. We saw tiny nests in the hummingbird aviary, several different types of rattlesnakes, tarantulas, scorpions, javalina, Mexican wolf, mountain lion, prairie dogs, an assortment of flourishing desert plants, delightful trails, spectacular scenery, giftshops, a coffee shop, restaurant, live shows, and much more. Wear comfortable shoes, and plan on spending a few hours. It's always a pleasure to visit here!
