Pha Din Pass is 30 km with 1.680mm above the sea level. It had become a legend of Dien Bien Phu Victory. It was the small trails and Viet Minh (the fathers and mothers of the Viet Cong) made up of the small road to supply the weapons and food. It was the most challenging way to use human power to pull artillery from Som La Dien Bien Phu. It was the only main and shortest route to support Viet Minh to defeat the French in Dien Bien Phu in 1954.

We cycle from the hotel, undulate 5 km through tiny towns along the river, and then challenge the Pha Din, which offers most of Vietnam's most incredible mountain landscapes. Venture through the spectacular karst mountains to the peak, view the scenery, and look over the most outstanding natural beauty. Take a ride descent in Binh Thuan. There are two roads between the middle part of the mountain top, and one is 13 km on a new road, while the old road is a well-maintained, smaller road with a similar distance, but without traffic at all. We cycle uphill for about 13 km and enjoy cycling downhill for 17 km.

You can choose which route to challenge, and we will be with you. The afternoon' ride is beautiful as it's more leisurely than in the morning adventures. The ride takes us through Black Thai hill tribes and green valleys, buffalos on farms and verdant fields of farm products. We will be back on the vehicle transfer to Son La city in the late afternoon.
