Mua Cave is one of the main attractions that you should visit when you take a trip to Ninh Binh city. This cave was built following the model of the "miniature Great Wall" in China, with nearly 500 steps up to the mountains to conquer. Hang Mua means "dancing cave" because King Tran used to come to this site to enjoy dance and song performances performed in this cave.
It's a tough trek with many uneven limestone steps (especially at the top), but every effort will pay off with the incredible panoramic view over the whole city.
