The Largest Caves on Earth
A limestone massif on the Laos border, riddled with cave systems on a scale that is difficult to photograph convincingly. Son Doong is the largest known cave passage anywhere.
Reaching Phong Nha takes effort, which is why it stays quiet. Two or three days covers the accessible caves, a river valley still farmed by hand, and a good deal of forest.

Planning Phong Nha
How do we get there?
Fly to Dong Hoi, then about forty-five minutes by road. It can also be reached overland from Hue in roughly four hours.
Can we visit Son Doong?
Only on a licensed multi-day expedition, booked far in advance and limited to a small number of permits each year. We can point you to the operator who holds them.
When are the caves open?
Water levels close some caves during the heaviest rain, usually October and November. February to August is the reliable window.
Is it suitable for children?
The larger show caves, yes. The kayaking and wet caves have age and swimming requirements we will check for your party.
