Vietnam
A 'dinosaur spine' ridge stairway climbing the Chinese border through seas of silver reeds.
They call it the dinosaur's spine — a stairway riding a ridge so narrow you can see into two countries at once. On one side Vietnam falls away in green valleys; on the other, China rises in identical hills. In late autumn the slopes turn silver with flowering reeds, bending in the wind like a tide.
Binh Lieu is a border district in Quang Ninh Province where the frontier patrol road and its stepped ridge paths have become northern Vietnam's most dramatic marked hiking country. The signature climb rides the 'dinosaur spine' to border Milestone 1305, steps and rest points the whole way, with Vietnam on one side and China on the other — a working frontier, walked on the official routes and on the border's terms. October gilds the lower valleys with ripe rice, and through autumn and into winter the slopes whiten with reeds. The district shares a province with Ha Long Bay and could not be less like it — Dao and Tay villages in cool mountain air, military history underfoot.
