Is this for you?
Who it's for
Families with older children who love an adventure story, and anyone curious about Utrecht's medieval past, can follow adventurer Lilliana Jonas past wharf cellars, city castles and Domplein, solving puzzles on the trail of a basilisk. It is free to play, about 2 km and takes around an hour and a half. If someone in your group struggles with uneven ground and changes in level, or you would rather ask a live guide questions, choose something else.
