Attendance and Cleanup After Rain

The lost and found will be open Monday from 10 a.m. to 5 p.m. at the Hilton Chicago’s Grand Tradition Room, People unable to retrieve items during that time can check the Lollapalooza website for more information.

According to past records, heavy rain at Lollapalooza has led to costly repairs. In 2011, organizers spent over $1 million to repair damage from a similar event, while 2019 saw nearly $650,000 in repairs after significant turf damage. It is still unclear how much this year’s cleanup will cost, but organizers are expected to release more details in the coming days.

Refunds and Road Closures
