Sanya Bay essentials

Address: Sanya Bay, Sanya, Hainan, China

Sanya Bay runs along the southern shore of Hainan and has a continuous beach approximately 22 km long, ending near a peninsula on the eastern side. Within the bay are two small islands, Xidao and Dongdao, and the artificial Phoenix Island resort lies near the eastern end of the beach. The setting combines an urban waterfront close to Sanya with stretches of palm-lined sand and low coastal development in places.

In recent years water clarity and coastal conditions in Sanya Bay have shown improvement and a few species of dolphins, including the Chinese white dolphin, have been seen off the coast from time to time, although they are not organized as a regular tourist attraction. Visiting typically means strolling the long shoreline, taking in open-sea views and sunsets, and spotting Phoenix Island from the beach; parts of the bay are busier near the city while other stretches are quieter.

  • Phoenix Island: The man-made resort island near the eastern end of the bay is visible from the beach and dominates the skyline at that end of Sanya Bay.
  • Xidao and Dongdao islands: Two small islands sit inside the bay and are notable coastal features when viewed from the shore.
  • 22 km beach and sunset views: A long sweep of sand offers extended walks and broad west-facing sunset panoramas over the water.
  • Urban waterfront: The stretch closest to Sanya city has a developed promenade and city skyline visible from the shore.
  • Occasional dolphin sightings: Dolphins, including Chinese white dolphins, have been reported off the bay on occasion, offering wildlife interest if spotted.

  • Plan outdoor beach time outside the heaviest rain months to avoid sudden downpours.
  • Walk along the beach toward the eastern end for the best views of Phoenix Island at sunset.
  • Check local advice before swimming, and be mindful of changing sea conditions.
