Yalong Bay Tropical Paradise Forest Park rises behind Sanya's best-known resort beach, trading sand for humid forest, ridge paths and broad views over the coast. Boardwalks, rope bridges and shuttle roads make the hills easy to navigate, while the viewpoints show how sharply Hainan's green interior drops toward the South China Sea.
It is a managed scenic area rather than wilderness, with photo platforms and paid attractions mixed into the forest. Go early for cooler air and clearer views, then use the park as a counterpoint to a beach-heavy Sanya itinerary.
