Located on the grounds of the Palace of Fine Arts the Exploratorium is a fascinating science museum that will add an educational aspect to your trip. Its highlight is the Tactile Dome, an interactive tour through total darkness where your sense of touch becomes your only guide. The Exploratorium is generally open from 10 a.m. to 5 p.m. every day except Monday and major holidays like Thanksgiving and Christmas. But it does open on Mondays such as Martin Luther King Day and Memorial Day that are holidays, so check the schedule first. Kids three and under are admitted for free. Admission is $9 for children four to 12, $11 for ages $13 to $17 and $14 for adults. But you might be better off buying a $17 Tactile Dome ticket (open to kids 7 and older) which also admits you to the museum.
