Xinghai Bay Sea Bath is the largest artificial sea bath in China, which consists of three small baths. The beach is 2,000 meters long and is paved with high quality sand transported from Beidaihe River. There are three tourist boat wharfs built in the bay, from which boats can go directly to Tiger Beach and Barrack Island. Two of the cruise ships are bottom-looking. Through the transparent bottom of the ship, the magical and changeable underwater world can be observed.
