The colorful hot air balloons slowly rise and take the awestruck visitors to the sky. They belong to the International Hot Air Balloon Festival, an annual event held in Hue, Vietnam.

The organizers expect the event to help Hue become a tourist hot spot. There are 5 countries participating in the hot air balloon show at the festival: Thailand, Malaysia, Japan, Netherlands and Vietnam.

The hot air balloons are allowed to fly freely at an altitude of between 100 and 300 meters, within a radius of 5 kilometers from the takeoff point.

Many hot air balloons with numerous distinctive shapes such as the octopus and hearts have appeared. Standing on these hot air balloons, visitors can admire the panoramic view of Hue, from a unique perspective./.
