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.
Haikou is a transport hub with flights to many cities and boats to nearby mainland cities such as Beihai and Zhanjiang.
Flight examples below with full cost economy class prices, but notice that discounts up to 50% are not unusual.
Local airlines Hainan Airlines and China Southern Airlines have domestic flights to many Chinese cities, as well as some international flights to neighbouring countries. In addition, Haikou is well-served by other Chinese airlines.
There is a train link between Haikou and Guangdong province (the trains are loaded onto ferries to cross the sea). So you can get the train from Guangzhou to Haikou. The trains actually start and finish in Sanya, but it takes about an hour by bus to get from downtown to the train station, and the train station in Sanya is also far from that city's downtown area.

Buses connect Haikou to many cities on the Chinese mainland, including Guangzhou, Hong Kong, Shenzhen, Guilin, and Nanning. Most buses are overnight sleepers. Buses are loaded on to ferries and arrive in Haikou at either Xingang port or Xiuying port. Here's a few examples showing journey duration and price.

The meter starts at ¥10, but it is customary to bargain before you get on, and a typical fare for a shorter trip is ¥15. The taxi from the airport is half an hour to the city centre.

Instead, walk out of the terminal building and you will see a line of licensed taxis. Before departing, insist on using the meter (dabiao) even if they are reluctant to do so. It should cost ¥50-60 to the city centre.
Buses are very inexpensive, but you need to know the routes.

When the tide is in, the roots of the trees are surrounded by water, giving the appearance that the trees grow directly from beneath the sea. This aquatic environment is ideal for breeding fish and shrimp and the leaves on the trees here are also said to have medicinal value. This particular type of tree produces seeds which sprout and propagate within their own shell. Tide times vary according to season, but when the tide is in there are some really fun boat trips to be enjoyed, winding in and out of the tree trunks and then on to the tiny island nearby, ripe with pineapple trees. The boat leaves from the entrance of the park when the tide is in. Each trip takes approximately one hour.

Take a tour to the northeast coast of Hainan Island - Wen Chang Shi, Long Lou Zhen (文昌市, 龙楼镇 Wénchāng shì, Lónglóu zhèn) to visit a Commercial Abalone Farm and & experience the shallow water diving for wild abalone. Our first abalone epiphany was that abalone are not bi-valves like clams or oysters. They are snails. Gross, yet cool. The farm produces almost 100,000 abalone a year. The water is changed daily, dumped out through fine membranes to catch the microscopic babies which are then laid back in clean water. The hoses are also used to inoculate the tubs with algae-plugs of green stuff are allowed to form in the hoses and then blown into the tub to make seaweed slushies. Visitors can buy the fresh live abalone at a very reasonable local farmer price (around ¥100 per 400g). Most of the abalone production is delivered fresh. Live abalone can survive for 30 hours. Farmer contact: Zhou Yi(周义), Address: Wen Chang Shi, Long Lou Zhen, Gu Song Cun (海南省, 文昌市, 龙楼镇, 红海村委会, 古松村). tel. +86 130 7891 5777 (Mandarin speaking).
The tropical weather of Haikou has attracted the Chinese all over the country to move to this island, along with their specialty. While most tourists don't come to Haikou for food, an impressive choice of foods is a hidden gem. The cooking style is a fusion of Cantonese, Hokkienese and certain Southeast Asian elements and seafood is impressive.
Prices have surged as the tourism industry is booming. In 2009, a dish of Chao Bing costs around ¥2 and in 2011 it became 4-6.

Compare to other places such as Sanya, Haikou is less touristy and a way cheaper to taste the local food.
Chao Bing (炒冰; chǎobīng) Literally 'stir-fried ice' in Chinese, it is a fresh-made sorbet-like dessert. First select your fresh tropical fruits. The fruits are blended. A device that looks like a frying pan is used to freeze the juice in a minute. This process, due to its super chill temperature, yields a very fine ice crystal and make the sorbet so smooth. Perhaps try a combination of Mango and Passion Fruit. Costs just ¥5. Good Chao Bing vendors can be found on San Xi Lu, just off Renmin Dadao, on Haidian Island in the north of Haikou.

Haikou traffic is a nightmare, said by many Chinese travelers, so expect to experience some of the worst traffic in China where traffic rule is nationally practiced half-heartedly. Cars and motorbikes can come in from any directions. Drivers will drive on anywhere as if they had right of roads. Even at some very obvious moments when a car is expected to stop, they don't necessarily.
According to some wikitravelers, at nights it is common to see a motorbike without a headlight lit up suddenly show up and come at a fairly fast speed. If you are not familiar with these reckless drivers, don't put your hope on them. Turn your precaution to maximum instead. Even if you are confident that you have enough experience with traffic conditions in many cities in China, expect it even worse here.
