Edinburgh, United Kingdom
This was a reallly enjoyable experience and I definitely recommend it. The guide, Lea, was obviously very knowledgable about the history of Edinburgh and she was very good at telling us the stories of what went on in the vaults as well as making us laugh. She did a great job at keeping us all together too through the busy streets so we didnt worry about getting lost in the throng. Definitely wear good shoes as it is a lot more uneven in places than I thought and expect to get dripped on. Highly recommended! A must see and do!
