Its breathtaking nature, sumptuous foods, and rich history has earned Xuan Dai Bay its rightful place in both history and tourism alike that a poem was made inspired by it:

Xuan Dai bay surrounded by mountains and sea

The natural landscape recalled

The vestiges of the ancient God temple

And Tien Chau boat festival

The two rivers join into one with the tide up and down

With reefs of scattered rocks on three sides

Green sea-pines on white sand ground

The forest in the natural site
