Anyone who wants to use a bicycle to investigate the city and its surroundings will find many bicycle paths and bicycle routes. The bicycle route planner for Frankfurt am Main and the federal state of Hesse (Radroutenplaner Hessen) provides interesting suggestions. There is also the 75-kilometre Green Corridor Bicycle Path (GrünGürtel-Radweg), which encircles the entire city, and a 10-kilometre bicycle path around the Höchst industrial park. Frankfurt is also connected to two long-distance bicycle paths (the R 3 and the R 8). There is no extra charge for taking bicycles onto local public transport, and many bike & ride places are available.
