Pacific Heights may be the local version of billionaire’s row but it has a much darker history which you can uncover when you join the SF Ghost Hunt Walking Tour. For two hours you will be guided to the haunted trees of millionaire abolitionist Mary Ellen Pleasant, past the Ghost Bride of California Street and various sites of unsolved murders as well as an early red light district. Better hurry to sign up, as many fall dates are already booked. $20. Guaranteed creepy.
