Join us on the 2nd and 4th Sundays of each month for Marine Science Sunday - a FREE engaging ocean-inspired classroom series from our education experts.

Our own backyard in the bay is full of amazing marine mammals!  Free classroom programs will highlight our local sea lions, harbor porpoises, dolphins, and even the occasional whale that wanders under the Bridge! We recommend teaming our free classroom program with a Guided tour at 11am, 1pm or 3pm for a truly immersive marine mammal experience.
