What is it?

Mystery City Games are a mix between a treasure hunt,  escape room, and walking tour. It’s a bit like the Da Vinci Code  – it’s about using clues hidden in the architecture of the city and magical objects to solve a mystery. It’s an outdoor escape room like no other and should definitely be included in your ‘top 10 things to do in Sintra’! No app or phone is needed – we think treasure hunts are more fun with real treasure maps, locks, and beautiful pieces.
