Hainan's ring railway

Hainan, China's tropical island province, is encircled by a high-speed ring railway — the world's first island loop line. It splits into an eastern ring (Haikou down the east coast via Qionghai and Wanning to Sanya) and a slower western ring (down the west coast via Danzhou). For the Haikou–Sanya journey almost everyone uses the eastern ring: the fastest services take about 1 hour 20–30 minutes, with trains running through the day.

Train vs flight

There are short flights between Haikou and Sanya, but on an island this size they make little sense: roughly 50 minutes in the air becomes three-plus hours once you add getting to the airport, check-in, security and the transfer at the other end. The high-speed train is city-to-city, cheaper, and turns up far more often. Unless you are connecting straight from an international flight at one of the airports, take the train.

Stations & tickets

In Haikou, eastern-ring trains leave mainly from Haikou East (海口东), with some from the main Haikou station and from Meilan Airport (美兰) — the airport station is convenient if you fly into Hainan and head straight to Sanya. In Sanya the terminus is Sanya Station, a taxi or bus ride from the resort bays of Sanya Bay, Dadonghai and Yalong Bay. Tickets are real-name; book on Trip.com or via the official 12306 system — see our 12306 English walkthrough.

Stops worth a break

Because the eastern ring hugs the coast, you can break the trip: Qionghai (for the Boao forum town and old riverside streets) and Wanning (for the Shimei Bay and Riyue Bay surf beaches) are both stations on the line. If beaches and surf are the point of your Hainan trip, a stopover turns a transfer into part of the holiday.

When to go

Hainan is a winter-sun destination: November to April is warm, dry and peak season — Sanya is busiest and priciest around Chinese New Year. Summer is hot, humid and the wettest, with a typhoon risk from roughly August to October. Trains run year-round; book ahead over the winter holidays.

Frequently asked questions

How long is the train from Haikou to Sanya?
On the eastern ring high-speed line the fastest trains do Haikou to Sanya in about 1 hour 20 to 1 hour 30; trains with more stops take up to about 2 hours. They run frequently through the day. Second class is roughly ¥85–105. Confirm times and fares when you book.
Train or flight between Haikou and Sanya?
Take the train. The flight is only about 50 minutes in the air, but with two airport transfers and check-in it loses to the ~1.5-hour, city-to-city high-speed train on both time and price for almost everyone.
What is the difference between the eastern and western ring lines?
Hainan has a full island-loop high-speed railway. The eastern ring (via Qionghai and Wanning) is the faster, busier route most travellers use. The western ring (via Danzhou and the west coast) is slower and more scenic but has fewer fast services. For a straight Haikou–Sanya hop, use the eastern ring.
Which stations do the trains use?
In Haikou, trains leave from Haikou East (海口东) and some from Haikou (the main station); Meilan Airport (美兰) also has a station, handy if you land and go straight south. In Sanya the terminus is Sanya Station, a short ride from the resort bays. Check which Haikou station your ticket shows.
