Brilliant fun - Spread it out over two days, a brilliant way to explore, this is our second one that we have done. Living in Oxford we have also done the Oxford mystery, discovering parts we had not explored. will definitely be doing more.

Excellent Tour of Old Portsmouth - Thank you so much - we had such a good day. It was so interesting and so well put together. There was only one clue that we thought was a bit dodgy! with the numbers on an arch - a bit of maths - but could get the answer anyway! We all know Portsmouth quite well but found out so much !! We have already recommended your 'tours'. Thank you

Great activity! - Really fun way to explore the town and learn history with a few good pubs along the way. Also done York and Manchester which again thoroughly enjoyable. Next stop Chester and plan to continue to enjoy solving mysteries ☺️

Highly Recommended! - The book is beautifully illustrated and the storyline intriguing. The clues test you out and fit together really cleverly. My daughter and I did this tour twice! First with a group of friends then with my oldest daughter when she was home from uni. We thoroughly enjoyed it both times and even found things we'd missed the second time round. We loved exploring Portsmouth and finding new areas we hadn't seen before. The only thing missing was a clue to where the nearest public toilets are! We'd highly recommend Mystery Guides for families and friends of all ages. We're looking forward to doing the Southampton one soon!

A fun mystery activity for all ages - A really well researched fun mystery. We learned some interesting facts and discovered new history about our home town. Definately recommend these mysteries. We also bought the Southsea Mystery which our son and his girlfriend loved.

Great day out - Great day out. Fascinating history lesson at the same time. All the clues were found, not always easily but great fun for adult family members to disagree!! Including a stop for lunch we made it last a few hours. Best value for money and entertaining day out.
