Each December thousands of lights illuminate the Victorians, shops, and trees along Union Street. Even the meters are disguised as giant candy canes (not that it makes parking tickets any easier to swallow). The neighborhood hosts holiday-themed events throughout the month, including free horse-drawn carriage rides, caroling and toy drives. Union St. between Van Ness and Steiner Sts (unionstreetsf.com) Dec 5 3–7pm. Through Dec 25. Free.
