Quick facts
When to go
The world's most spectacular cave systems, from cathedral-sized underground chambers to mud baths, zip-lines, and rivers that disappear into darkness.
Feb – Aug is the busiest window in Phong Nha Caves, so accommodation and flights go first. Book ahead. The shoulder weeks either side are usually quieter for the same reason.
Getting Around in Phong Nha Caves
- Motorbike rental: $5–7/day from any hostel. Semi-automatic bikes are easiest. International driving permit technically required but rarely checked
- Distances between caves: 15–30km on well-paved roads. The main road through the national park is scenic and mostly flat with light traffic
- Bicycle rental ($2/day) works for Phong Nha Cave near town but not for Paradise Cave or Dark Cave which are too far. Hostels run shuttles for $3–5 each way
