San Francisco's Mission Bay gets an early jump on the fall season this year. Thrive City, the public plaza surrounding Chase Center, is hosting Thrill-O-Ween on October 24, and it is shaping up to be one of the more straightforward family Halloween events in San Francisco this October: outdoor, daytime, and built for a few easy hours out rather than a late-night affair.
According to Eventbrite, the event is hosted by Thrive City and described as an "immersive, outdoor Halloween experience" designed as a kickoff to the fall season, with a full afternoon of activities for all ages. A special screening of E.T. is part of the lineup, and organizers note that guests should stay alert, since surprises may pop out along the way.
What to Expect at Thrive City
The plaza will be set up with a costume contest for the best-dressed guest, live entertainment, trick-or-treat stations, a mini pumpkin patch, a photo op, and an arts and crafts area. It is a lineup built for families looking to spend a few hours outside without needing to leave the city.
A practical note for anyone planning to go: food and beverages will be available for purchase at Thrive City's on-site restaurants and bars, so there is no need to plan a separate meal around the visit. Parking is available seven days a week at the Chase Center Garage on Warriors Way. Space is limited and admission is first-come, first-served, so it is worth checking the official Eventbrite page for the latest ticket details before heading over.
Thrive City itself is worth knowing about beyond this one event. According to Chase Center, it is an 11-acre, privately financed, mixed-use complex in the Mission Bay neighborhood, home to retail and restaurants that ring the arena year-round, not just on game nights. That is part of why it keeps showing up on our list of things to do in Mission Bay: it was built to function as a neighborhood gathering space, and afternoons like this one are exactly what that was meant for.
