Son Doong Cave was formed 2-5 million years ago, when the river flowed through the limestone mountain area and was buried. The water eroded limestone and created an underground tunnel. In soft limestone areas, the collapse of tunnel ceiling formed large holes, which became giant domes afterward. The cave is about 200m high, 200m wide and at least 8.5km long. With these tremendous dimensions, Son Doong Cave is considered as the world’s largest cave.
