Are the tree houses the world highest?

Yes, we take pride in building so high, 30 – 40 metres (100+ ft), that you can observe the forest canopy from your bed. Only Irian Jaya Papoo natives build that high up in the trees. However, our construction techniques are quite different.

What is the price for each option ?

The price for each trek is around €100 per day, with seasonal variations. You will know the exact fare for the period on the tour page.

Is there a special price for kids?

Yes, we offer about 50% discount for children under 12.

In short, what is the difference between the Classic and the Giant options?

Classic: two nights, more relaxed overall schedule, with chances of gibbons and wildlife sightings.

Giant: one night only, steeper initial walk, more zip lines, the biggest tree in Laos, and no gibbon sighting.

For this price, will I get luxury accommodation?

No. Environment is jungle and service is local. You will get exceptional canopy setups, friendly escort and natural outdoor conditions. No five-star hotel… but sometimes a thousand stars at night!

You will be sleeping in canopy level tree house only accessible by ziplines and share your tree house with other guests from your group. Each mosquito net provides semi-private room for 2 people. When a tree house is at full capacity, solo travelers may end up sharing a mosquito net.

Yes, tap water comes from a nearby spring and is filtered for drinking.

* Please let us know in the booking form if you have any special dietary requirements.
Where can I store my luggage and valuables?

We have a dedicated safe storage room for your extra luggage in our office. Our office is under video surveillance.

Will I see gibbons?

Gibbons are wild and free in the National Park; we are visitors in their environment. It is not guaranteed that you will see gibbons. Gibbons are relatively easy to spot in the morning at any season because they “sing”. Heavy rain, severe cold or mood, will discourage them from calling even though they remain in the same area.

For chances of gibbon sightings, you should choose the Classic option (including Honeymoon) as the pace is calm and you have more time to be on the lookout for wildlife in general.

You will not see any gibbons during the Giant loop as they very rarely come to that area.

What other wildlife lives in this forest?

Sambar deer, barking deer, leopard/golden/clouded cats, wild pigs, over 100 species of birds, civets, giant squirrels, Asian Black bears, langurs, macaques, loris, snakes, lizards, etc. Our inventory keeps expanding…

However, it is difficult to observe them due to low density and shyness of the species, as a result of human hunting throughout South-East Asia. Still, the Classic Gibbon Experience program is one of the best options to spot wildlife in Laos.

You will be given a pdf eBook of the biodiversity of Nam Kan National Park when you complete your booking.

Do I need to be in good physical condition?

Depending on the option you choose, in the dry season, you should be able to walk uphill at least one hour per day (200 – 300m denivelation). We welcome guests aged 8 to 65 in the Classic Option and 12 to 65 in the Express. If you know you have a certain allergy or weakness, please bring your medication and further enquire with our office.
In the rainy season, treks are more slippery and our guests are usually younger and in good physical condition.

I am subject to vertigo: should I join?

When we started operation, we used to discourage people with strong vertigo to join our treks. However, and surprisingly, most of our guests suffering vertigo who actually joined confessed their vertigo had lessened while living in the treetops.

Usually each year, one of our guests has to sleep at ground level and occasionally some people completely overcome their fear of heights.

Is there a minimum age to join The Gibbon Experience programs?

Classic (3 days 2 nights): 8 years old.
Express (2 days 1 night): 12 years old.

What sort of guide will I get?

Your guides were generally born in the village nearby. Most of them have helped building the Gibbon Experience project. Some have a good English level while others don’t and should rather be referred as escort. We strive to bring the level up and value your feedback forms on that aspect.

What are the working conditions of my guide or the cook in the kitchen?

Gibbon Experience staff all have proper working contract, a work insurance, regular holidays, flexibility to choose to work 10 to 30 days a month depending on farm work, gets a mix of monthly salary, daily allowances, efficiency bonus and annual bonus. This adds up to 180 – 330 USD on a monthly basis and is much higher than average Lao or even Thai rural salaries. Tip is always welcome but please don’t reward someone pretending he’s exploited!

Where does the money go?

How long are the cables?

Shortest : 50 m – Average : 235 m – Longest : 570 m

How many tree houses are there?

We are operating 3 treehouses in the Classic at the moment and 2 in the Giant loop.
More treehouses are under maintenance and will be opened soon.

What about transportation to the National Park?
For the Classic tour (which is located deep in the National Park), the car travel time from the office to the village is about 2 ½ hours. It is a difficult 83km trip that is either dusty or muddy depending on the time of the year. Where the car stops, you will meet your guide who will show you the way. On the last day, you should arrive at the office at around 3 pm (an additional 1 or 2 hours during the rainy season).
For the Giant loop, the car travel time from the office is about 1 hour. Road access is easy and initial walk takes 1 ½ to 2 hours. On the second day, you should arrive at the office at around 3 pm (an additional 1 hour walk out is likely to occur during the rainy season).
You will be driven to the National Park in a “songtaew-style” pick-up with open-air seating in the back. The road condition in certain areas is not the best and may result in a bumpy ride, sometimes shared with other villagers. Additional walking time may be added during the rainy season if the car cannot make it to the end of the road.
Is there a good hotel to stay at in Houayxai and should I book one ?

There are plenty of guesthouses (hotels and hostels) with prices ranging from 100 000 – 300 000 (Little Hostel, Oudomphone, Sabaidee, Thaveesinh…) to 200 000 kips (Boat landing, Houayxai Riverside) per night.

You rarely need to book, especially during this post-covid time.

When is the burning season?
Field burning is a common agricultural practice all throughout Southeast Asia.
Although it is usually less present in Bokeo than Northern Thailand or some other parts of Laos. The period and intensity are very variable, the smoke can be noticed as soon as January and disappear with the first rains (May-June). Last year in the region, the intensity peak was end of April, beginning of May.
There is usually a haze, more or less opaque depending on winds. Over the years, our tours went on as usual. Rarely, on a few days, such as last year when we had forest fires, people with respiratory conditions unaware of this regional practice, preferred to cancel. If you have such conditions, we recommend avoiding that season all together.
