A Pa Chai is located in Muong Nhe district, Dien Bien province and 750km from Hanoi. A Pa Chai is situated in the extreme western part of the country, would have been the last place receiving sun light, but in fact this land is located above sea level of about 1.800m.

From Dien Bien Phu city, there are many ways to A Pa Chai. The most popular route is going through Muong Cha - Muong Nhe - Chung Chai – the 405 Leng Su Sin border station - Ta Kho Khu - 317 A Pa Chai border station. This route has a total length of nearly 280 km.

To get to the border T-junction, visitors must be approved and licensed by the border guard command of Dien Bien. It is interesting that instead of having to hire locals to lead the way, visitors will be guided by soldiers of the 317 border station. And it takes about 4 hours to walk 15km through the forest and crossing streams to get to the destination, this is not only a challenge to your health but also the will of conquerers.

The road is very steep, rocky, which goes through the jungle and tall, sharp reeds. It is now the early dry season so the road to A Pa Chai is somewhat easier to go. In the rainy season, the road will become slippery.

However, the road to A Pa Chai is always covered by fog so the narrow, winding and bumpy road to the Landmark 0 becomes formidable challenge to anyone. With a steep slope, you will have to go straight to the peak.

Without a strong will and determination to conquer, you may be submitted by the cold of the northwestern mountains and the extreme tiredness after many hours of hiking.
