Hot air ballooning is a recreational activity that involves flying in a large balloon filled with heated air. The hot air inside the balloon is lighter than the cooler air outside, allowing the balloon to rise. A burner, fueled by propane, heats the air, and the pilot can control the altitude by adjusting the temperature. During a flight, passengers enjoy scenic views from high above the ground. The balloon is typically tethered to a basket, which can carry several people. Hot air balloons are often used for festivals, special events, and sightseeing tours, providing a unique perspective of the landscape below.
