Brave San Francisco’s dark and ghostly past during this walking tour of haunted San Francisco. After meeting at the city’s famous Union Square (after dark, of course), a local guide escorts you down haunted alleys, through mysterious hotels, and around historic street corners. Stand where the Zodiac Killer met his final victim, learn of paranormal activity following mysterious deaths, visit the site of Tessie Wall’s storied brothel, hear about Gold Rush–era hauntings, and how the Black Plague ravaged the city twice. Your tour ends back near Union Square. This tour is not recommended for children under 10.
