Excellent in every way, another one is definitely on our " to do " list. - An excellent way to spend a Sunday morning around Old Portsmouth and finish as the pubs opened! Clues all good and flat walks with some steps not too arduous. Your historical commentary an added bonus both humorous and educational.

Such a fun way to explore history - Mystery Guides gave us a fascinating opportunity to explore Old Portsmouth. The mystery trail was fun to do and had us scratching our heads on several occasions; it wasn’t just a tick box exercise. But that made it more fun as we needed to use our powers of observation to answer some of the clues and we noticed so much more about the area around us. We spent several hours in the area and finished up at a quay side pub in the old town sitting outside with a well earned drink. We’ll definitely be doing more of these!

History, Clues and Sunshine in Portsmouth - This was a great way to spend a few hours with our nephew and niece on a sunny day in Portsmouth. Despite the mystery adventure being pretty much on our doorstop, we learned some interesting things about the history of the city and visited places that we would not normally go to. The guide book is really well laid out and once we enjoyed solving the clues as we made our way onwards the final destination and revealing the suspect. We highly recommend and look forward to trying other cities.

Tapping the Admiral - This has to be a 'favourite'. The historical facts relating to Nelson, John Pounder and all the gruesome murders that took place here were fascinating. Food at the Dolphin was very good too!

Looking for dimonds in Portsmouth - Enjoyed the experience, seeing parts of Portsmouth we may have not done without the Guide. As expected some clues were harder to find then others, but we resolved the mystery. The diamonds will go with Nelson to his grave.
