Head downstairs from the cable-car terminus to the visitor center, where multilingual staffers answer questions and provide maps and pamphlets. Muni Passports are sold here, and you can pick up discount coupons—the savings can be significant, especially for families. If you're planning to hit the big-ticket stops like the California Academy of Sciences and the Exploratorium and ride the cable cars, consider purchasing a CityPass (www.citypass.com/san-francisco) here. The CityPass ($86, $64 ages 5–11), good for nine days, including seven days of transit, will save you more than 40%. The pass is also available at the attractions it covers, though if you choose the pass that includes Alcatraz—an excellent deal—you'll have to buy it directly from Alcatraz Cruises.
