Two indoor tanks at the Ocean Institute contain touchable sea creatures, an accessible man-made tidepool, as well as the complete skeleton of a gray whale. Anchored near the institute is The Pilgrim, a full-size replica of the square-rigged vessel on which Richard Henry Dana sailed. You can tour the boat Sunday 10 to 3:30. Weekend cruises are available. In addition, marine-mammal exploration cruises are offered January to June.
