The "Große Wiese" sports and brine park is characterized by the Finnenbahn. 1,000 meters long and 2.50 meters wide, the circuit offers a completely new running experience. Although running on the wood chips is unusual and strenuous at first, it is easy on the joints and back. Use is free of charge! Every runner can train there whenever they want. The Finnenbahn is illuminated daily until 23:00 using energy-saving LED technology.
