Butterfly Haven Yoga

A Saturday morning yoga class inside the Judy Istock Butterfly Haven at the Peggy Notebaert Nature Museum, from 8:30 to 9:45 AM. The setting is the main draw — expect to unroll your mat among tropical greenery and free-flying butterflies. BYO mat and water bottle; museum admission is included in the ticket price ($24 to $30, depending on how you register). Open to adults 18 and older, with advance registration required and no drop-ins allowed.
