$15 regular admission, but still need to pay extra to go in special exhibits, like the Rain Room. Children under the age of 17 are free. California residents with CA ID get in for free after 3 pm daily. The line was super long. Highly recommend that you purchase the ticket online the day before. We ended up purchasing the dual membership for $110 with 1 special exhibit free and get in to the Rain Room for $10 each person. We could go back the whole year with the membership. With the membership...if the other member is not going, that member could bring another person in for free got the whole year.
