With the average temperature a pleasant 25.5 C all year-round, Yalong Bay is situated in the southernmost part of Hainan Province, 25 kilometers (about 15.5 miles) away from the tropical seaside tourist city, Sanya. The scenery is amazing, with endless rolling hills, serene gulfs, clear blue sea and silvery sand beaches--three times as long as any in Hawaii.

    Home to several well-preserved coral reefs with tropical fish of varied kinds, colors and shapes, the ocean here is crystal clear, allowing visitors to view underwater sights up to 10 meters (33 feet) deep from the surface.
