Pha Din Pass has a total length of 32km. It’s located on Highway 6, which is divided between Son La and Dien Bien provinces. The old Lai Chau (now Dien Bien) and Son La also handed down a story about dividing the two provinces by a horse race over Pha Din.
People and horses, the same strength come from two pass ramps, where the meeting place on the pass is also the boundary line. And the pass belongs to Lai Chau which is a bit longer. But it does not matter, because this pass is the pride of the two provinces. Because it is challenging the adventurous people to get the beauty that is hard to resist on the top of the pass.
Challenging is because, Pha Din is also a pass with a great slope from 12% to 19%. The mountain pass is meandering in figure 8. There are many sleeves with high slope and curve radius of less than 15m. Geology here is also very weak in the rainy season often occurs sliding, blooming, slipping and landslides.
Today, the National Highway 6 renovation and renovation project, Son La – Tuan Giao section. It has been completed.
