Enjoy the beauty and tranquility of the Son River (Sông Son), the main river flowing through Phong Nha town and past the entrance to Phong Nha Cave. Its clear, emerald waters wind through the stunning karst landscape, offering beautiful reflections and peaceful scenery.

Find a spot along the riverbank to relax, go for a refreshing swim in the Son River (check locally for safe spots), or enjoy the views from riverside cafes and restaurants. The river is the lifeblood of the area and central to the Phong Nha experience.
