Join Open Space Rangers for an exciting, spooky family Halloween event! The festivities will run from 6:30 to 7:30 PM and include fun activities and a photo booth. The East Bay Vivarium will be on site with creepy animals, offering a chance to see them up close and learn fascinating facts. At 7:30 PM, we will embark on an interactive Graveyard Stroll featuring a cast of ghostly characters. Appropriate for all ages. No pets are allowed, except for service/companion animals. Dress in layers and wear sturdy shoes. Adverse weather or poor air quality may cancel. Check the calendar or call (415) 473-2816 two hours before the event to confirm the status.
