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.
