Helicopters take off from the square in front of the provincial stadium.
After the opening ceremony, the Northern Helicopter Company supported two flights to visit the world natural heritage, Phong Nha - Ke Bang National Park.
Phong Nha - Ke Bang National Park is located in the administrative boundaries of 2 districts: Bo Trach and Minh Hoa, about 50 km from Dong Hoi City. The park is located in a limestone mountain area of about 200,000 hectares. In the park, there are about 300 large and small caves, many unique underground rivers, a diverse ecosystem with many rare species of flora and fauna, so Phong Nha - Ke Bang is known as the "kingdom of caves".
In 2009, an expedition team from the British Royal Cave Association discovered and announced Son Doong Cave, with a length of over 5 km, a height of 200 m, and a width of 150 m, as the largest cave in the world. Son Doong Cave is one of the highlights of these tourist flights.
Thanh Nien Online reporters were on the first helicopter ride to explore the "cave kingdom" from the air.
