Ripley's Believe It Or Not Museum is one of the most enjoyable, fascinating fun activities for families and groups. We highly recommend this FUN museum. Located in the heart of Fisherman's Wharf. Two floors and over 10,000 square feet filled with the strange, the unusual, and the unbelievable! See in person the incredible "Believe It or Nots" you've read about in the Ripley books and cartoons and seen on television.
