Last year, a team from US-based Warner Bros, has surveyed a cave at Phong Nha-Ke Bang National Park in Quang Binh province to select scenes for the film Peter Pan.

UNESCO's World Heritage Site of Phong Nha-Ke Bang, is situated in a 2,000sq.km limestone zone, some 500km south of Ha Noi. It is well-known for its cave and grotto systems, comprising more than 300 caves with a total length of over 70km including Sơn Đoòng and Én (Swallow caves).

According to provincial leaders, this is a good opportunity for the province to attract visitors and elevate its image in the world.

Last year, the province received 2.8 million visitors, a doubled figure against 2013. Among them, foreign arrivals saw a strong growth rate of nearly 27%.
