About Hainan Island#

Hainan Island is the main island of China’s southernmost province, located in the South China Sea. It is a tropical to subtropical island and serves as a major domestic and international holiday destination.

Beaches, resort towns and coastal tourism are the primary visitor draws, with coral-reef dive sites, coastal promenades and luxury hotels concentrated on the southern and eastern shores. The island also contains tropical rainforests and inland scenery that attract nature tourism and outdoor activities.

Hainan was established as a separate province and a special economic zone in 1988, which spurred rapid infrastructure and tourism development. Since then the island has expanded airport, ferry and hotel capacity to support both domestic and international visitors.

Geographically it lies off China’s southern coast across the Qiongzhou Strait from Guangdong Province. Major cities on the island include the northern capital Haikou and the southern resort city Sanya.

  • Administrative status: The island province was established as Hainan Province and designated a special economic zone in 1988, accelerating modern development and tourism.
  • Best time to visit: Typhoon season runs mainly in summer and early autumn, while winter months offer warm, sun‑reliable conditions that attract visitors from northern China.

What to See#

  • Haikou: The provincial capital on the island, located on the northern coast, serves as the administrative and transport hub with ferry and air links to the Chinese mainland.
  • Sanya: A major tourist city on the southern coast known for beaches, resorts and international hotels; the city is the island’s principal winter-sun destination.

How to Get to Hainan Island#

Hainan’s main gateways are Sanya Phoenix International Airport (southern coast) and Haikou Meilan International Airport (northern coast). Domestic flights link Haikou/Sanya to major Chinese cities; high‑speed rail connects Haikou to mainland Guangdong via the Qiongzhou Strait tunnel/bridge network. Ferries operate to nearby islands and to the mainland from Haikou and Sanya.

Tips for Visiting Hainan Island#
