Hang Vom

Hang Vom is a natural limestone cave located inside Phong Nha-Ke Bang National Park in Bo Trach District, Quang Tri Province. Situated near Phong Nha town, it is part of the extensive Phong Nha cave system and is known for its pristine stalactite formations, underground river passages and surrounding primary jungle. Accessed only by guided trekking tours, it offers an adventure caving experience within the UNESCO World Heritage site.

Visitors can expect a remote jungle trek to reach the cave entrance followed by exploration of a wild, undeveloped cave with large chambers, stalactites and stalagmites, and river passages. The setting is dense forest and karst mountains inside Phong Nha-Ke Bang National Park. There are no built walkways or lighting; exploration involves hiking, scrambling, wading and swimming with helmets, headlamps and life jackets provided by tour operators. Access is only with licensed guides.
