Oceanic Society Expeditions is a non-profit organization conducting educational and enjoyable natural history day cruises, nearly year-round, to experience the Bay Area's fascinating marine life: whales, dolphins, sea lions and sea birds. Expert naturalists lead all trips and explain the natural history of gray whales, and how they have recovered from near extinction. Trips leave from San Francisco, Half Moon Bay, and Bodega Bay. Voted best whale watch by San Francisco Bay Guardian.
