Museum admission is free the first Wednesday of every month. Note: August Free Day is the busiest day at the Exploratorium--attracting four times as many visitors as a typical weekend day. As parking is limited and we anticipate large crowds, plan to arrive early to find parking. The museum typically reaches capacity early in the day and waiting times to enter can be as long as 2 hours. Please plan accordingly.
