Haikou, also known as the "Coconut City", is the capital city of Hainan Province, the strategic city of the Belt and Road. It is the north end of Hainan Island and adjacent to Wenchang to the east, Chengmai to the west, Ding’an to the north and Qiongzhou Strait to the north.
Situated in the tropics, Haikou is a coastal city featuring beautiful coastal scenery and a comfortable climate. The coastline of Haikou is 136.23 km (272.46 miles) long. Most of the coasts are vast and continuous, with fine white sand. There are many coastal swimming areas in the offshore where the water is clear and the waves are flat all year round.
Haikou has evolved from a simple sightseeing city to an attractive seaside resort and business center. The services for visitors to the city are being extended with the aim of establishing the city as Southern China's key center for tourism.
