Cave tours to the recently-discovered Tu Lan Cave system, 70 kilometers from the Phong Nha - Ke Bang National Park in Quang Binh province, have now been connected to tours to the Tien 1 and Tien 2 Cave systems.

Hidden away in the woods and giant limestone mountains of ‘the land of caves’ in Quang Binh Province, Tien Cave (the Cave of Fairies) is an almost ‘anonymous’ destination that has yet to be featured on tourist maps.
