Spiders are everywhere, and this is the perfect time of year to see spiders of every shape, size, and color. We’ll learn how they hunt, how they make their webs, and how to identify many common species. Total miles: 2. There is little elevation change but there is a short, steep climb between the parking area and the main trail. This walk is offered in partnership with Marin Water. Remember to bring lunch. No pets (except service dogs) are allowed. Adverse weather or poor air quality may cancel.

Registration is required. Use the automated system to sign up or cancel; event leaders do not manage registration.
