Yalong Bay is a broad, curved beach about 7.5 kilometres long on the southeastern side of Sanya. The shoreline is lined with large international and domestic resorts that market the bay as the Yalong Bay National Resort, giving the area a polished, purpose-built feel.

The eastern end of the bay is occupied by the People’s Liberation Army Navy as part of the Yulin Naval Base, and that section is not open to the public. Offshore there are coral formations and relatively calm water pockets that attract snorkelers and divers, though reef health and visibility vary with weather and tides.

Visiting the bay feels resort-oriented: wide sand, promenades and hotel beaches with facilities, along with numerous water-sport options organized by hotels and local operators. Away from the resort fronts you can find quieter stretches and coastal paths for strolls, but facilities and public conveniences are concentrated near the main hotels.

  • Main crescent beach: A long sweep of sand ideal for beach walks, sunbathing and watching sunrise and sunset over the bay.
  • Snorkeling and diving spots: Shallow reefs and clear patches offshore make snorkeling and introductory diving popular activities through local operators.
  • Resort promenades and spas: Upscale hotels line the bay and provide promenades, spa facilities and restaurants that shape most visitors’ experiences.
  • Coastal walks and quieter coves: Walk away from the main resort clusters to find less crowded stretches of sand and simple coastal trails.
  • Naval base viewpoint (from a distance): The eastern section is occupied by the Yulin Naval Base and is off-limits, but it is visible from public areas along the bay.
