General admission is about $16 for adults and $11 for children ages 3-13, with additional fees for the planetarium and submarine tour. Open Tuesday through Sunday 9:30am-5:30pm, closed Mondays except Oregon school holidays. The earthquake simulation exhibit and the life science lab are the top picks for kids ages 4 through 12 and easily fill two hours. Skip the submarine tour with strollers or kids under 5 as it involves steep narrow ladders and tight quarters. Plan at least three hours and visit the cafe on site for a mid-visit lunch break rather than trying to leave and re-enter.
