Great exploration and story - Had a lot of fun with the story and visiting different locations. Even better than I expected and good for our group of adults and teenagers. We did it in two halves in the end, took about three hours including some short stops at two of the excellent pubs en route!

A great adventure for English students at Queen Mary - I took a group of English students from Queen Mary University of London on the Grail Trail as part of my Magical Narratives course, which is about medieval romance and its modern reincarnations. We'd been reading about the Quest for the Holy Grail all term and this brilliant walking tour gave us the chance to go in search of it ourselves! The tour takes you through some beautiful parts of London - St Paul's, Clerkenwell, Temple, Covent Garden - and the clues are interspersed with fascinating bits of history about the Grail legend and the places visited. Easy-to-use app, clear instructions. Great fun and my students and I loved it.

Fun and fascinating! - What a brilliant experience - I absolutely loved it! You follow the story, which leads you through the streets, squares and alleys of London and asks you to find certain clues to allow you to continue the story. It's like a treasure hunt and fun history lesson all rolled into one. The app was really user-friendly, the "tasks" were very doable and the distance walked felt about perfect. I liked that you could either read the story on your phone or listen to it through headphones as you walked and looked around you. I will definitely be doing the other trails in the series.

Great hunt showing some... - Great hunt showing some of the oldest parts of London that as a local even if never spotted before! Questions are easy but was great for a family of 4 with 2 teens for a bit of fun. A lot of pubs on the way too if you don’t have kids with you 😁

Great tour - loved doing it at my own pace. - Absolutely loved the tour! It took me to places I didn’t know. It was great fun and informative. I enjoyed stopping off on the way and doing it did it at my own pace. I needed to check something with Alex; he immediately responded, going out of his way to assist. I am really looking forward to booking some of the other tours.

A great way to see old London with new eyes - What a wonderful way to discover a secret London, hidign in plain sight! Enjoyable and educational in equal measure, with pubs, cafes and restaurants strategically located at key points along this walk, I spent a delightful three hours peeling away layers of a modern city to reveal a a dramatic medieval mystery. The game uses your phone to send you clues and messages as you progress along the trail, with a liberal does of really fascinating info on the Templars, the Grail, and the role London played in one of the greatest puzzles in history. I certainly see Braintree in Essex differently now! Put on some comfy shoes and treat yourself to a walk about a lovely part of London!

Fun, imaginative walking trail with clues, history and fascinating parts of London - A really imaginative mystery trail to find out where the Holy Grail might be hidden. The route takes you round some really interesting historic parts of London and you end up seeing places you might have walked past many times before and never noticed. You are also given bite-sized chunks of historical info which really helps bring the area to life, and it's amazing how the clues all seem to come together to point in a particular direction for the grail! Fantastic fun.
