The Bai Tho Mountain is 106 m high. It runs along the coast, half on land and half in the sea. Sailing in the bay, one or two hundred meters from the mountain, one can see a poem carved on a flat stone cliff. In 1468, Emperor Le Thanh Tong, who was also a poet, made an inspection TRIP of the North-East region. He stopped at the foot of the mountain, and inspired by the magnificent beauty of his surroundings, he wrote a poem. Later, he had the poem engraved on the wall of the mountain. It is very interesting to climb the mountain and enjoy the panoramic view of the bay.
