Children
Accompanied children 10 and under do not need a ticket to enjoy 99% of Bumbershoot; however, every person entering the Mainstage requires a ticket, regardless of age. If you would like to take your child into the Mainstage, you may purchase a Mainstage Upgrade onsite during the Festival, as available. Please note, the Mainstage has a limited capacity, and has the potential to sell out in advance of Bumbershoot. All children 10 and under must be accompanied by an adult.
Parking
Off site paylots, garage and street parking. Discounted carpool parking is available at select Seattle Center parking lots.
