Such a fun group activity around London! We chose HiddenCity’s Moriarty’s Game (my husband is a Sherlock Holmes fan) and it was perfect. We did it as family group of 3 and it took us just over 4 hours, (including a couple of great pub stops along the way - also having clues to find therein). I also think it would suit larger groups of mixed ages too as there are lots of clue elements to solve. We had lots of laughs as well as tested our detective skills - and intelligence! Having lived in London for over 30 years, we discovered completely new areas we’d never been to before which was another unexpected bonus!

We found Moriarty a top notch problem solving trail around pretty and interesting corners of Mayfair. Went with a friend and our teenage sons. There’s so few activities that are truly parent/teen bonding time and satisfying fun. This was the second HiddenCity trail we’ve done, we also loved Spectre. Thoroughly recommend these for an activity with friends, young adults and for families with older kids.
