Fodor's Expert Review Desert Botanical Garden

Opened in 1939 to conserve and showcase the ecology of the desert, these 150 acres contain more than 4,000 different species of cacti, succulents, trees, and flowers. A stroll along the ½-mile "Plants and People of the Sonoran Desert" trail is a fascinating lesson in environmental adaptations. Kid-centric activity areas encourage tactile play and exploration. Specialized tours are available at an extra cost; check online for times and prices.

The Desert Botanical Garden stays open late, to 8 pm year-round, and it's particularly lovely when lighted by the setting sun or by moonlight. You can plan for a cool, late visit after a full day of activities.
