When travelling the Ha Giang Loop, Quan Ba is likely to be either your first stop after Ha Giang Town, or your last stop before returning to where you started and leaving the province behind. The most popular activity in Quan Ba is trekking, specifically trekking around the amazing landscape to visit a plethora of charming minority villages such as Nam Dam or Lung Tam. The town of Tam Son is the capital of Quan Ba, and is often the first stop travellers make in the district. The town, like most others in the province, is surrounded by karst mountains, two of which are known as the “Twin Mountains” and are closely tied to a local legend that we won’t spoil for you here, as hearing it for the first time as you watch the valley from atop the peak is a key part of the experience.
