An interactive whodunit hike around the Teufelssee. This outdoor escape game takes you to Bad Freienwalde, you have the mission to solve the case about the disappeared environmental activist Clara Resista and prevent an attack on the local ecosystem. You have to discover the last trace of the former open pit mine and free Clara from her dungeon. Mighty beaver castles await you as a reward, and on hot days the spring-fed lake invites you to swim. Equipped with tablet, pen and a list of suspects, you start your hike. Exciting puzzles and tasks await you along the way. If your team manages to free Clara, the environmental activist, who knows the area well, will give you some exciting information about the flora and fauna along the way. The mission takes about 45 minutes of pure running time and leads through somewhat rough terrain, which is why you definitely need sturdy shoes. The hike leads past imposing beaver castles and through a beautiful mixed forest with ancient beech trees. In search of clues, you cross the valleys and gorges of a terminal moraine landscape shaped by the Ice Age, which is rather untypical for Brandenburg. Since the play area is in a nature reserve, the execution is agreed upon with nature protection authority and forester. In total, the mission lasts about 3 hours. The mission can be carried out from Friday to Sunday between 9 am and 5 pm.
