The 279 Route was one of the most important route connecting the NorthWest Vietnam together
It start from Hạ Long city and go through - Hoành Bồ - Sơn Động - Lục Ngạn - Chi Lăng - Văn Quan - Bình Gia - Na Rì - Ngân Sơn - Ba Bể - Na Hang - Chiêm Hóa - Bắc Quang - Quang Bình - Bảo Yên - Văn Bàn - Than Uyên - Quỳnh Nhai - Tuần Giáo - Điện Biên Phủ - Điện Biên.
As time goes by, many part of this route has been destroyed and became challenged offroad tracks for bikers. One interesting part of this route is Na Hang - Chiem Hoa - Bac Quang, since the Hydropower site in Na Hang town launched, it sinked the route and the only way to travel it is take your bikes on boat.
