This San Mateo County park, about a 30-minute drive south from San Francisco, provides both brooding Cypress bowered walks and sunny beaches frequented by sea lions. The rocky seashore hosts a living community of marine life that is of great interest to visitor and naturalist alike. A variety of seaweed, crabs, sponges, seastars, mollusks, and fish make their homes in the inter-tidal pools, that area between low and high tide. Be sure to check a tidal chart to know the period of lowest tide. Wear good-gripping, salt water compatible, footwear so you can wander about the rocky tide pools for an up close encounter with these critters.
