A hot air balloon can’t be steered in the usual way, but according to wind direction and speed. The pilot skillfully controls the balloon’s height by regulating the temperature inside the balloon envelope.
Therefore, how far you fly depends on the weather and wind conditions on the actual flight day and how long it takes for the pilot to find a suitable landing spot.
You can fly anywhere from a very short distance up to 35 km, but typically the flight is between 10 and 20 km long.
