The Best Sight in The Loop, including the West Loop and South Loop, Chicago

Escape winter's cold or revel in summer sunshine inside this huge "landscape art under glass" structure, which houses tropical palms, spiny cacti, and showy blooms. A children's garden has climbable leaf sculptures and a tube slide that winds through trees. The Sugar from the Sun exhibit focuses on the elements of photosynthesis—sunlight, air, water, and sugar—in a full-sensory environment filled with spewing steam, trickling water, and chirping sounds. Don't miss the historic Jens Jensen–designed Fern Room with its lagoon, waterfalls, and profusion of ferns. On-site events include botanical-themed fashion shows, seasonal flower shows, and great educational programing.
