Go-Karting involves driving open-wheeled vehicles, around a circuit. It is a great way to get into motor sports, as Go-Karts tend to be easy to drive. There are just two pedals to drive - the accelerator (to speed up) and the brake (to slow down and stop).
If you have never actually seen a Go-Kart before, they are open-wheeled vehicles (with four wheels) that sit very close to the ground. This means that unlike a normal car, you have to sit very close to the ground. This can feel strange at first, but it is something that you quickly get used to.
