About this place
The largest known cave passage in the world by volume, inside Phong Nha–Kẻ Bàng National Park. It was found by a local man, Hồ Khanh, in 1991 and surveyed by British cavers in 2009. There is no day visit: access is by a multi-day expedition with the single licensed operator, booked far ahead.
This enormous mountain cavern dating back millions of years offers guided exploration tours.

Why is there no rating on this page?
Because it would be someone else's. Trip2VN publishes no guest score of its own and does not reproduce them from booking platforms. What you get here are facts about the place; the judgement stays yours.
