Haikou, known also as the 'Coconut City', is the capital of Hainan Province, China's second largest island. The city is the provincial administrative center of Hainan as well being the focus of the local economy, culture and transportation. Haikou stands at the northern end of Hainan Island, on the west bank of the Nandu River estuary. This river is the longest on the island and the city's name appropriately means 'Mouth of the Sea'. With the sea on three sides, Haikou enjoys a long coastline that features excellent bathing beaches and seaside resorts. Holiday Beach is the most popular of these, while Xixiu Beach is where the National sailing and windsurfing teams train and hold competitions. 

Besides its natural resources, Haikou has a number of important sites of historical interest. The Wugong Temple (The Five Official's Temple), the Tomb of Hai Rui and the Xiuying Emplacement each serve as reminders of the historical importance of Haikou.

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 Haikou as Southern China's key center for tourism.
