How high can an hot air balloon go?

Hot air balloons can typically reach altitudes of around 3,000 to 5,000 feet, but some can ascend even higher, with records exceeding 10,000 feet. The exact altitude depends on factors such as the balloon's design, weather conditions, and the amount of fuel available. However, beyond certain heights, the lack of oxygen and temperature drops can pose risks to both the balloon and its occupants. Safety regulations often limit commercial hot air balloon flights to lower altitudes.
