Phong Nha itself is small, but what surrounds it is anything but. Some four hundred caves, a national park you can lose days in, and a valley behind the village that will swallow an afternoon before you notice. You are not going to see all of it, and you do not need to.
A few things really belong on your list: at least one big cave, one day on a scooter and one moment where you are simply lying in the water. Other things are on every list because they are always on every list, and they are fine as long as they do not eat the half day you wanted for the valley. And there is one popular stop we have mixed feelings about ourselves.
So where is your time here really well spent, and what can you happily fit in around it?
Still planning? Our Phong Nha page has how many days you need, where to sleep and how to get there.
The Bong Lai Valley by scooter
For us this is the best thing you can do in Phong Nha, and it is at the top of almost nobody’s list. The valley lies about seven kilometres behind the village: rice fields, small farms, limestone mountains and roads where you can go half an hour without meeting anyone. Where the caves show you what nature made here, the valley shows you how people live here.
You rent a scooter for about five euros a day and just ride into the valley. There is no entry fee, you only pay at the stops you pick. Half a day is enough, a whole day is more fun. If you want the barbecued chicken at the Pub with Cold Beer, you have to order it hours ahead, so swing by in the morning.
Head back late in the afternoon, so you ride the last few kilometres at sunset. That is when most travellers are already back in the village waiting for their night bus, and it is exactly when the valley is at its most beautiful.
Our verdict: the best thing you do here, and the part most people miss
Paradise Cave, before nine
Paradise Cave is about 31 kilometres long, and plenty of travellers call it the most beautiful cave in Vietnam. You walk along a wooden boardwalk through chambers so big that it takes a few minutes to work out where the ceiling is. Stalactites tens of metres long, and a silence you will not find anywhere else in Vietnam.
Entry is about nine euros and the cave is open daily from 7.00 to 16.30. It is twenty kilometres from the village, so by scooter you are there in just under half an hour. Wear shoes with grip, because the rock is wet everywhere.
Get there before nine. After that the coaches arrive and an empty cathedral turns into a queue on a wooden staircase. There are cows on the road on the way, so ride slowly and keep your helmet on.
Our verdict: before nine you have it almost to yourself, after that come the coaches: same ticket, different cave
Dark Cave: zipline, mud and kayak
This is the opposite of Paradise Cave: where you wander quietly there, here you come out wet, filthy and out of breath. You zipline across the river, swim into the cave, wade through a mud bath deep inside the mountain and then kayak back out. Of everything in Phong Nha, this is the one backpackers keep talking about longest.
Count on about twenty euros for Dark Cave, and on a full day if you combine it with Paradise Cave in the same tour. Zipline, mud bath, kayak and life jacket are usually included. Bring a torch or a power bank, because inside it really is pitch black.
Leave your phone loose in your pocket and it is gone, because at some point you simply go into the water. Put it in a waterproof bag or leave it with your things.
Our verdict: absolutely, unless tight dark spaces are not for you
Phong Nha Cave by boat
The cave the village is named after, and the only one you enter by boat. You get on a small boat in the village, cross the Son river and then glide onto an underground river, into the mountain. The engine is cut, someone picks up the paddles, and after that it is just the water lapping against the walls.
The trip takes about an hour and you can simply arrange it in the village. You can also do it as a tour together with Paradise Cave: then the boat is included and you have done the two best-known caves in a single day.
Keep it for a different day from Dark Cave. Getting wet twice is fine, but three caves in a row is where they start to blur together.
Our verdict: make time for it, if only for that silence on the water
Mooc Spring Eco Trail
A jungle trail that ends at clear blue water between the rocks, where you can just jump in. After a morning in a cave or a day on a scooter in the heat, this is exactly what you need. You can kayak here too, or do nothing at all for hours, which works just as well.
Entry is about seven euros. Bring swimwear, because the water is clear and cold, and that last part feels better than it sounds.
Do check the calendar: Mooc Spring is usually open from April to August, and after that the water is too high. Coming in autumn? Save it for another trip and pick one of the places that are open then.
Our verdict: at its best when it is hot
A hike in the national park
Almost everyone comes here for what is underground, while the park above it is on the same UNESCO list. Limestone mountains, thick jungle and trails where you barely meet anyone, with plants and animals you will not see elsewhere in Vietnam. For a day without a helmet, a torch or mud, this is the best option you have.
Entry depends on the route you choose and starts at around six euros. Plan on half a day to a full day. Good to know: some routes may only be walked with a guide, so ask about that in the village before you get on your scooter.
Do this on your last day, once you have seen the caves. Only then does it hit you how big the area is that you have been riding through all this time.
Our verdict: half a day to a full day, and the best way to finish once you have done the caves
A night in Hang En
Hang En is the third largest cave in the world and lies in the same park as Son Doong, the biggest of them all. You hike there through the jungle on a guided trip and sleep on a sandy beach inside the cave, with an opening in the ceiling where the light falls through. This is not a sight you tick off on the way past, this is the reason some people come to Vietnam.
It always goes with a guide, so you arrange it in advance, and you need at least three days in Phong Nha for it. Some routes in the park are guide-only anyway. Expect this to be by far the most expensive day of your trip through Vietnam.
Worried about the money? This is the kind of spending almost nobody regrets afterwards. Worried about your fitness? Ask beforehand how many hours a day you walk and how steep the descent into the cave is.
Our verdict: only if you have the days and the budget, but then without hesitation
Got time to spare in Phong Nha?
Two caves instead of three
The caves are close together and it is tempting to do three in one day. Two caves on two mornings leave a bigger impression, and you keep an afternoon free for the valley. Paradise Cave and Phong Nha Cave make a beautiful pair.
The Duck Stop in the valley
The Duck Stop costs about three euros including duck food and it is a lovely stop along the way: you walk among the ducks, you eat something and it is relaxed. There is a part where you get to stand on a water buffalo, and that is one we pass on ourselves. Go for the ducks, the food and the atmosphere.
Evenings in the village
Phong Nha Village is one main street, and it goes quiet early in the evening, which suits the early mornings you have here perfectly. Eat at your homestay, because most of them cook and do it well, and then go and sit by the river with a sixty-cent beer.
Keeping an eye on the season
This is the one place in Vietnam where the season really decides what goes ahead. From February to August the park is at its best. If you are in the village in September, October or November, ask every morning which tours are running rather than booking ahead, because high water closes caves and cancels kayak routes.
Our top five in Phong Nha
Only got a few days? These are the five we would do no matter what:
- Half a day to a full day on a scooter through the Bong Lai Valley, back at sunset
- Paradise Cave, early in the morning before the coaches
- Dark Cave with the zipline, the mud bath and the kayak
- Phong Nha Cave by boat, along the underground river
- Mooc Spring Eco Trail to cool off, between April and August
Still got time after that? A guided cave trip with a night in Hang En is the biggest thing this region has to offer. Don’t have those days? Then just ride into the valley again, and this time take a side road you rode past the first time.
So what do you really have to do in Phong Nha?
Honestly: nothing on this list is compulsory. Caves are also something where two feel amazing and four start to run together, so pick two properly rather than working your way through all of them. Fill the day you have left with a scooter ride through the Bong Lai Valley, and for a lot of people that turns out to be their favourite day here.
If we had to pick just one thing: rent that scooter. One big cave shows you why this area is on the UNESCO list, but an afternoon in the Bong Lai Valley shows you how it smells, sounds and lives. For many backpackers that is exactly the part they loved most, and it costs you five euros.
And plan one morning where you do nothing. Sit by the Son river with a coffee, look at the limestone peaks on the other side, and only then decide whether you want another cave. In a village this quiet, that is not wasted time. It is the point.
