Utrecht is known for its position as the heart of the Netherlands. The City Trail takes players through the city at their own pace: on the smartphone they solve riddles and complete challenges that lead from place to place, past De Dom, Pieterskerkhof, the Winkel van Sinkel, and the Filmboulevard among others. It is an independent treasure hunt without a guide, where the team with the most points wins.
