Caves, terraces, waterfalls and wild places of Vietnam, season by season
Places
Four places, four different calendars
The four landscapes this guide covers in depth have almost nothing in common except distance from the nearest airport. This page compares them on season, travel time, access rules and the reasons to leave each one out.

How the four fit together
Three of the four are in the far north, within a long day's drive of Hanoi but a long way from each other. Ban Gioc and Dong Van both sit on the Chinese border, in Cao Bang and in the former Ha Giang province respectively, and travellers often link them along the border roads. Mu Cang Chai lies to the west, on the road between Hanoi and the Sa Pa area, and pairs more naturally with the north-west than with the border east.
Phong Nha–Ke Bang is in the narrow centre of the country, close to the Lao border. It has its own airport at Dong Hoi and a station on the north–south railway, so it fits a route along the coast rather than a loop through the mountains. The national parks of Cuc Phuong, Cat Tien and Bach Ma are covered on the wildlife page rather than here, because the question there is what you will see, not how to get in.

Matching the places to a month
No single month suits all four. September is the nearest thing to a shared window in the north: the rice is golden at Mu Cang Chai and on the Ha Giang terraces, Ban Gioc is still full after the summer rains, and the passes are drying out. The trade-off is Phong Nha, where the rainy season begins around October and many caves become unreachable until the new year.
For a trip built around caves, March to August works, with the cave expeditions starting earlier in the year. For a trip built around water on the terraces, aim for the last days of May and the first week of June, and accept that Ban Gioc will be rising rather than at its fullest. The nature calendar shows the overlaps month by month.

How many days each place needs
- Phong Nha–Ke Bang: two full days covers Phong Nha Cave by boat and Paradise Cave; add a day for Hang Toi or a day trek, more for multi-day caves.
- Ban Gioc: a night in Cao Bang city and a long day out, or a night near the falls to see it in the early morning.
- Mu Cang Chai: two nights, because the viewpoints are spread over 25 to 30 kilometres of mountain road and cloud can hide them for a morning.
- Dong Van: three to four days from Ha Giang city on the road loop, more if you walk.
These are planning estimates based on the distances in the sources on each place page, not rules.
Places not covered in depth, yet
Sa Pa, Hoang Su Phi, Dray Nur, the Dak Nong and Lang Son geoparks, and the caves of Ha Long Bay and Trang An appear on the understanding pages — the calendar, the terraces, the waterfalls, the geoparks — rather than as places of their own. We would rather write four places properly than twelve thinly. If you have been somewhere recently and found the facts different from what we say, the contact page is the way to tell us.
Common questions
Questions readers ask
Can I combine Ban Gioc and Dong Van in one trip?
Yes. Both are on the Chinese border in the far north. Allow several days, because the roads between them are mountain roads, and avoid the summer rains when landslides close sections.
Which place is easiest to reach from Hanoi?
Phong Nha, by flight to Dong Hoi, in terms of time. By road, Ha Giang city and Cao Bang city are each six to eight hours from Hanoi.
Is there a month that suits all four?
No. September comes closest in the north, but Phong Nha enters its rainy season from October.
Why are national parks not on this page?
They are covered on the national parks and wildlife page, which deals with what you can realistically see.
