If your time at the circuit is limited, book the two hour guided tour of the circuit. See behind the scenes of a racing track in areas usually closed to the public such as the television gallery and the mechanics' workshops. There's also the chance to stand on top of the famous winners' podium you have seen so many times on television.
Getting behind the wheel and driving the track yourself is a hugely popular option at Silverstone. Book online for a wide variety of driver experiences which usually include you driving several laps in a high powered road car, then a lap as a passenger in a F1 style car. It's an experience you will never forget.
In addition to the Grand Prix, SIlverstone hosts Moto GP motorbike racing, endurance events and motor racing featuring various grades of car and driver. Book your tickets online for the stands, or consider upgrading to a premium hospitality package including a meal.
