Looking for a fun weekend or summer day outing for the family?  Head to Santa Cruz and use these four passes to visit a working UCSC marine laboratory!  Exhibit halls, aquariums, touch tanks, tours to the marine mammal research overlook and unsurpassed vistas of the Monterey Bay National Marine Sanctuary. The kids can hold a sea star -- marvel at the world's largest whale skeleton -- touch a shark-- think like a scientist!  What a fantastic way to spend a day.
