It is planned to set up a circular trail network for mountain bikers, the “Grenz-Trail Waldeck-Frankenberg”. The aim is not only to create a network of routes as a circular route, but also to create a network of 6-7 trail parks. This means that a self-contained trail network consisting of two or three laps of different lengths is created at individual locations or locations. These individual trail parks are then linked to attractive, also single-track-heavy connecting routes. It will thus create Europe’s largest contiguous trail network with approximately 650 kilometres of track (border trail including local trail parks). In the first step, this application is intended to enter into the planning and planning of the project in question.
