Join Rangers at Agate Beach in Bolinas for a fun tide pooling experience during an exceptionally low tide known as a "minus tide." The low tide won't last long, so make sure to arrive on time. We'll watch for mossy chitons, giant green anemones, octopus, porcelain crabs, and black turban snails, making sure to respect the tide pool creatures we encounter! Make sure to bring sturdy, waterproof shoes and warm clothing. We will provide warm drinks. This event is ideal for ages 5 and older. No pets (except service dogs) are allowed for this excursion. Adverse weather or poor air quality may cancel; if in doubt, text or call (415) 301-1616 two hours before the event to confirm the status.
