    We loved it and would highly recommend!

    We absolutely loved this and would highly recommend! It’s such great fun and an amazing way to see the beautiful and historical sights whilst learning interesting and unusual facts and essentially playing a real life version of cluedo! (All in your own time)

    History, mystery and fun!

    I've done other walks and treasure trails, but I still learnt some fascinating facts. I loved the clues, some of them were quite cryptic and you had to think outside the box. It's a really well put together book and treasure hunt. Great for spending time and working together.

    A perfect pastime

    This was a great way to spend a few hours. We loved the look and straightforward layout of the hunt that took us round a very attractive route. The interesting facts were a bonus adding the ideal amount of detail between clues.
