Blue Bay, Hainan
Blue Bay–also know as Clearwater Bay–is in Lingshui County in Hainan. It's an undiscovered little corner of paradise that is mostly farmland and unspoiled beaches. There's a great deal to explore, from Boundary Island to Diaoluo Mountain Nature Reserve. The area is expecting 30 new hotels to open in the next few years, so now is the time to go visit.
