About Quan Ba

Quan Ba is the first highland you climb into after leaving the city. At the top of the pass, the Quan Ba Heaven Gate opens onto the valley of Tam Son and the Twin Mountains, and the landscape changes from green hills to the grey karst of the Dong Van Karst Plateau.

Local tips

  • Most people only stop at the Heaven Gate viewpoint for ten minutes. Stay a night in the valley instead — mornings here are quiet and misty.
  • Afternoon light is best for the Twin Mountains; mornings are often foggy in the cool months.
