Since 1904, the Ravinia Festival in Highland Park has been delighting the public with its three month summer seasons of across the board musical performances. From Yo-Yo Ma to Louis Armstrong, the Ravinia Festival pays tribute to all musical genres, hosting 120-150 events per season and attracting up to 600,000 listeners. Pavilion seats allow for a nice view of the stage and lawn seats are more suited for a relaxed, picnic-style spread. The Ravinia Festival is a great way to escape the stress and activity of the city.
