Jelly Belly Tour
About an hour north of San Francisco, in Fairfield, California, you’ll find the home of Jelly Belly jelly beans. Among the fun facts you’ll learn on its free 40-minute walking tour: why it takes about seven days to make a single candy (jellybelly.com or 800-953-5592).
Future of Flight & Boeing Tour
Take off to Mukilteo, Washington, to see how planes—747s, 777s, and 787s—are made. The 90-minute tour takes you into the actual Boeing plant, and there are interactive exhibits and displays to explore too. Tickets are $15.50 for adults and $8 for children 15 and under, but note that there is a four-foot height requirement (futureofflight.org or 888-467-4777).
