Hang Thủy Cung is a water-filled cave near Phong Nha—shoot dramatic stalactites, mirrored pools and tight passages where light shafts and reflections create abstract compositions. Visit in dry season (Feb–Apr) for lower water/more access; mornings bring softer light and fewer visitors. Access typically requires a short boat/guide and modest entry fee; bring a headlamp, protective bags and check local opening times. Paths can be slippery—good footwear recommended.
