At Dadonghai Bay, Mandarin Oriental, Sanya unfolds across a private stretch of coastline, where villas, gardens and low-rise buildings follow the curve of the South China Sea. Guest rooms, suites and villas use terraces, timber details and tropical materials to draw the setting into the interiors, with many categories oriented towards the water. Restaurants, beach spaces and open-air lounges keep the resort informal yet polished, while pools, spa pavilions and landscaped paths give guests room to move through the grounds.
