The Bean Hollow Trail is a fun and simple 1.7 mile out and back hike. Lots of cool dogs (all of them on leash). Easy drive from San Fran, Palo Alto, San Jose or anywhere in between. Check out Smugglers Cove when you go past it! Watch for whales, seals, otters, and poison ivy. This trail is also known as Arroyo Del Los Frijoles.
