Big cats, monkeys, elephants and giraffes await at the 500-animal Santa Barbara Zoo , where you'll also find beautiful gardens. The Humboldt penguins are the current stars, and these tuxedoed show-offs seem to know it. If you're in need of a giggle, hit the 'Eeeww!' insect exhibit. Its hissing cockroaches and giant African millipedes will leave you giggling at the grossed-out kids. Or deeply disturbed. Parking costs around US$3.
