A 7.5-km crescent of white sand - the benchmark beach.
Yalong Bay is Sanya's signature beach: a 7.5-kilometre crescent of fine white sand swung between forested headlands, with palm lawns and a line of international resorts behind the tideline. Chinese guidebooks crowned it 'the No.1 Bay Under Heaven' long ago, and one look at the turquoise water shows why.
The public beach is free and open around the clock - sun loungers, umbrellas and water sports are paid extras run by the resorts and beach vendors. Calm, warm water makes the bay the island's hub for snorkelling, diving and jet-skiing, and the November-to-April dry season delivers the clearest seas and the most reliable sunshine.
There is more than sand here: the Shell Museum at Central Square, the leafy walk-through Butterfly Valley, and the ridgeline trails of Tropical Paradise Forest Park, which look down on the full sweep of the bay. Sanya has no metro, but public buses, taxis, DiDi rides and hotel shuttles all reach the bay with ease.
