The residents of Poperinge are called Keikoppen. Sometime there even was a Keikoppen association in Poperinge! During the Knappe Keikoppentocht Mister Ghybe, chairman of the association, drags the young detectives (starting from 8 years old) along through the city to a lot of special places with a rich history. At this places the young detectives need to fulfil playful exercises. Those who can crack the code become an official member of the Keikoppen association! The distance of the tour is 2,5 kilometres and it takes around two hours to finish it. You can pick up the plan for free at the tourism office of Poperinge.
