Tien Son Cave

About this location

Tien Son Cave - A million-year-old "stone palace". Tien Son Cave is located in Phong Nha Commune, Quang Tri Province, within the Phong Nha - Ke Bang National Park. Situated about 1,000 meters from the entrance of Phong Nha Cave at an elevation of approximately 200 meters above sea level, it was discovered in 1935. Unlike Phong Nha Cave, which is a wet cave, Tien Son is classified as a dry cave with a surveyed length of over 980 meters. The interior winds along the mountain slope and stands out for its diverse stalactite formations, creating distinct spatial layers and clear visual depth. According to the Management Board of the National Park, the current tour route only covers about 400 meters from the entrance as the terrain deeper inside becomes hazardous. The approach to the cave also involves climbing nearly 600 steps, transitioning filmmakers from the external limestone landscape to an enclosed, low-light, and geologically rich subterranean environment. With its dry cave characteristics, stalactites, and limestone terrain, this location is well-suited for nature documentaries, science films, exploration projects, and productions requiring natural cave settings, particularly for scenes emphasizing the scale, depth, and pristine nature of underground spaces.
