Sanya Bay boasts one of Hainan's most stunning beaches, where the 25km coconut-fringed shoreline feels like paradise. Famous for having the best sunset views in Sanya, the sands turn golden-red at dusk—don't miss snapping the 'fire cloud' phenomenon. Try parasailing or nighttime beach BBQs, and visit the lively seafood market where fishermen sell their catch straight from the boats—it doesn't get fresher than this!
