Bring out your inner Detective Sarah Lund with Mystery Makers' interactive mystery hunts. Offered at numerous historical sites around town – including Kastellet – players are given fictional identities and a mystery to solve, with a series of riddles and clues along the way. Suitable for adults and kids aged 12 and above, it’s a stimulating, engaging way to explore Copenhagen’s back-story.
You will need a minimum of four people to form a team. See the website for pricing, which varies according to the day of the week and time of day (Sunday to Wednesday before 3pm is cheapest). Mystery Makers also runs a series of excellent, one-hour Escape Room games (from 200kr).
