Address: Riyue Bay, near Wanning, Hainan, China

Sun and Moon Bay (Riyue Bay) sits on the southeast coast of Hainan, about 25 kilometres south of Wanning. The bay is roughly 4.5 km long and forms a wide, curving stretch of coastline.

The bay has been the site of numerous surfing events and is known within China as a surf venue; the Sun and Moon Bay Haimen Tourism Area is located along the shore. The open aspect of the bay creates space for beach and surf activities.

Visiting the bay feels more low-key than the larger resort centres on Hainan: facilities and services are concentrated around the tourism area and nearby villages, while long stretches of coast remain relatively quiet.

  • Riyue Bay surf area: The bay’s breaks are the main attraction for surfers and spectators during competitions and good swell days.
  • Sunrise and sunset: Wide views along the curved bay make for dramatic sunrise and sunset light across the water.
  • Sun and Moon Bay Haimen Tourism Area: The tourism area clusters local amenities and gives easy access to the main beach and shoreline.
  • Coastal walk and fishing boats: A walk along the shore reveals small fishing boats, rocky headlands and quieter stretches of sand away from the main tourism zone.

Getting There & Around

How to Get to Sun and Moon Bay#

The nearest town is Wanning, about 25 km north; the Shenzhou railway station lies roughly 15 km northeast of the bay. Hainan is served by island airports and a high-speed rail line that connects the main coastal cities.

To cover the last stretch to the bay, take a taxi or local road transport from Wanning or Shenzhou station; local roads lead down to the tourism area and beaches, so check schedules and road conditions locally.

Tips for Visiting Sun and Moon Bay#

  • Bring strong sun protection and water - much of the shore is exposed with limited shade outside the tourism area.
  • If you plan to surf, check local conditions and any organised events before you go, as crowding can vary with competitions.
  • Expect amenities to be concentrated around the Haimen tourism zone; pack essentials if exploring quieter stretches.
  • The last road to the bay is coastal and local - taxis are the simplest way to reach the main beach from nearby towns.
