Saguaros are large, treelike, columnar cacti native to the southwestern United States and Mexico. Here in the U.S., Saguaros are found in the Sonoran Desert of western and southern Arizona and southeastern California. A good place to see them is in Saguaro National Park near Tucson, Arizona.

Saguaros bloom here in late May and June, so if you want to see these majestic cacti blooming, you have to brave the summertime desert heat, which can easily top 100 °F (37.8 °C) during the daytime.

Even when Saguaros are not in bloom, these iconic symbols of the American West are still an impressive sight.
