Haikou (海口 Hǎikǒu) is the provincial capital of Hainan Province in southern China and is at the north end of the Hainan island.
Haikou is a tropical coastal city with a population consisting mostly of immigrants from other provinces. As one of the least developed provincial capitals, Haikou has a somewhat laid-back atmosphere but many development projects are in progress. Many streets in Haikou are quite different during the day compared to the evening. Small outdoor restaurants and stalls fill the streets in the evening and many areas are at their busiest from 9.00pm to 1.00am. Local favourites are BBQ stalls which serve cheap local beer till late. You will soon notice the abundance of coconut trees within Haikou. Most streets are lined with them. It is greener than most Chinese cities and has decent air quality. The downtown does not have many tourist attractions and the water in its only beach area is murky but as a transport hub, it can be conveniently served as a base for traveling to some cities on the north of Hainan.
