Hung Thoong Valley

The Hung Thoong cave system is located deep in the strictly protected area of Phong Nha – Ke Bang National Park, surrounded by a system of million-year-old limestone mountains and primeval forests. Hung Thoong is one of the most pristine places in Phong Nha – Ke Bang, including 3 large caves: Hung cave, Tron cave, and Thung cave. Inside the cave beautiful blue lakes like the scene in the movie “Avatar” along with many small caves and million-year-old stalactites, can be found. With constantly changing terrain from walking through the forest, climbing over rocky mountains, swimming through underground caves, wriggling through dry caves and camping in the midst of the Phong Nha – Ke Bang forest, visitors will immerse themselves in nature, and enjoy the feeling of soaking in cool streams and mysterious caves.
