Ocean travel Hainan
Hainan’s sea area holds 600-plus islands, reefs and sandbanks. The island coast runs about 1,944 km, with dozens of bays that work for a beach day or a longer stay.
Coast and islands
South-coast bays such as Yalong, Dadonghai and Sanya Bay are the easiest resort bases. Haitang Bay is the duty-free shopping shore on the same coast.
East-coast Riyue Bay is the surf beach. Smaller islands, including Wuzhizhou, are day trips for clearer water rather than a separate holiday.
What to do
Swimming, shoreline walks, snorkeling and boat days fit most first trips. Diving and sailing need a licensed operator and a weather window; ask what the boat covers before you pay.
A beach base plus one inland day is enough contrast. The central rainforest is a drive or a rail-and-transfer, not a walk from the sand.
How to plan
Three to five nights covers one coast. Add nights if you want both Sanya and Wanning without packing every morning.
Fly into Sanya Phoenix or Haikou Meilan, then use taxis for bay hops and the island-loop high-speed rail for longer jumps.
