Boston Children's Museum will be open late to celebrate summer and play with the Summer of Play Carnival! This after-hours celebration will be from 6:00–9:00pm and will include carnival games, performers, foods, prizes and more!

The Summer of Play Carnival is a limited capacity event and advance tickets are required. Tickets are $25 per person and include admission to the Museum, unlimited play at the game stations, and fun prizes for all children at the end of the night.
