Rambling among red rock formations with vistas in nearly every direction, the Desert Botanical Garden will make you feel like you’ve left the city for the country. Show-offs are bristly headed barrel cactus and ornamental grasses. Don’t miss the Desert Discovery Loop Trail (about 0.3 mile) along a yucca forest, and the Sonoran Desert Nature Loop Trail (0.25 mile) through stands of organpipe cactus.
