This is the photo of a young woman who is praying in front of Y A Na Goddess in Huyen Khong Cave. Young nubile girls often come here to pray for happy marriages. About 8 km southwest of Da Nang city, Huyen Khong is one of the largest and most beautiful caves with many interesting legends. The cave looks like an overturned giant bell with the flat foundation and the high arch receiving light and air through the five natural holes in the exterior of the cave.
