In 1468, during his inspection tour to the eastern region, King Le Thanh Tong stopped here. Inspired by the stunning beauty of Halong, the King wrote a poem and had it carved into the southern side of the mountain, hence its name Bai Tho (Poem).
In 1729, Lord Trinh Cuong composed a poem in response to that of King Le Thanh Tong and also had it carved near the former. The mountain features other poems by Nguyen Can and some other poets. Atop Bai Tho Mountain, you feel surprised at the magnificent landscape of Halong Bay.
In the background of immense emerald waters, of rock bobbing, of high sky, of surrounding flowers and trees, you can figure out the tiny images of boats. Bai Tho makes up one of the beauty spots of Halong.
