32 of the 137 circuits we list will take a 6 year old, across 27 counties.
This is the part that catches people out. Nearly every circuit sets a minimum height alongside the minimum age, and both have to be met. A child needs to reach the pedals with enough leg left to brake hard, and see over the wheel, and a kart has almost no adjustment. Among the tracks that take 6 year olds, the minimum runs from 100cm to 130cm. Measure your child before you book rather than after you arrive.
22 other circuits do not publish a height minimum for this age. Worth ringing before you travel.
13 circuits open up at this age that would not take a 5 year old:
