Join Ranger Lauren to kick off the Halloween season in a spooktacular way! Join us for a Halloween-themed scavenger hunt in nature. Treats (and tricks) will be provided. This is a family-friendly event best suited for ages 5 and up. Friendly dogs are welcome but must be leashed. Dress in layers and wear sturdy shoes. Adverse weather or poor air quality may cancel; if in doubt, call (415) 473-2816 two hours before the event to confirm the status. Registration required.
