The first port of call for a racetrack experience is the Hockenheimring on the Rhine plain, a good hour and a half by car from Obertal. The Grand Prix circuit, around 4.6 kilometres long, has written Formula 1 history and is open to ordinary visitors surprisingly often these days.
During the public driving sessions, the Touristenfahrten, you can take your own car onto the track, from sports cars to the more ambitious everyday car. Driving takes place in time slots, for as many laps as your concentration allows. Check the dates in advance, follow the helmet and vehicle rules and be realistic about your own brakes. The track is less forgiving than a country road.
