Capture one of Ha Giang's most iconic images at Quan Ba Heaven Gate, the gateway to the Dong Van Karst Plateau Geopark when traveling north from Ha Giang City. This mountain pass offers the first truly dramatic vistas of the loop, including the famous Quan Ba Twin Mountains, also known affectionately as the Fairy Bosom mountains, nestled in the valley below.

Standing at the Quan Ba Heaven Gate viewpoint, visitors are treated to sweeping panoramas of rolling hills, winding roads, and the town of Tam Son spread across the valley floor. The main attraction, however, is the pair of perfectly rounded, verdant hills rising side-by-side from the flat valley floor – the Twin Mountains. Local legends attribute their unique shape to mythical origins, adding to their charm.

Stopping at Quan Ba Heaven Gate is an essential early highlight on the Ha Giang Loop. It provides a stunning introduction to the scale and beauty of the karst landscape that defines the region. The easily accessible viewpoint and the unique sight of the Twin Mountains make it a popular spot for photography and a moment to appreciate the natural artistry of Northern Vietnam.
