In this article, we'll introduce you to some of the most common and iconic cacti species found along the Sonoran Desert Loop Trail.

Saguaro (Carnegiea gigantea)

The majestic saguaro is perhaps the most iconic symbol of the American West. Reaching heights of up to 70 feet, these towering cacti can live for up to 200 years in the right conditions. Found throughout the Sonoran Desert, look for them along the loop trail's ridgelines and hilltops.

Teddy Bear Cholla (Cylindropuntia bigelovii)

With their fuzzy appearance and tendency to cling together in clusters, it's easy to see why this cactus is often called the "teddy bear" of the Sonoran Desert. Be careful not to touch these spines, as they can cause painful puncture wounds.

Prickly Pear (Opuntia spp.)

Prickly pear cacti are some of the most common and widespread in the Sonoran Desert. With over 30 species to choose from, these plants come in a variety of shapes and sizes, but all share one thing in common – those pesky spines!

Beavertail Cactus (Opuntia basilaris)

This low-growing cactus is often overlooked by hikers, but its unique beaver-like shape makes it a standout. Found along the loop trail's lower elevations, keep an eye out for this interesting species.
