Coming to Quang Binh tourism, in addition to long-standing famous caves such as Phong Nha - Ke Bang and Son Doong, there is also a cave system that is still quite wild and mysterious, the beautiful Tu Lan cave system. Located in Minh Hoa district, Quang Binh province. Exploring Tu Lan cave is considered one of the most difficult trips, only 1 level behind exploring Son Doong cave. To fully experience the beauty of Tu Lan, visitors must have the perfect combination of walking, exploring caves, climbing and swimming.
