The management board of Phong Nha-Ke Bang National Park has said that U.S. Travel Channel has finished a TV report exploring the imposing landscape of caves on Ke Bang Limestone Mountain and surrounding areas.

The channel has filmed En Cave--the third largest cave in the world and Tu Lan Cave in the north central province of Quang Binh.

In a meeting with the national park’s managers, Travel Channel representatives said they hoped to introduce beautiful nature of the national park to visitors from hundreds of nations and territories.

Phong Nha-Ke Bang National Park is home to the world largest cave Son Doong which was discovered in April, 2009 and several of other caves in Quang Binh.

With assistance from local men, the British Royal Cave Research Association has explored the cave system in Phong Nha-Ke Bang since 1990.
