With a range of around 7 kilometers long beach and abundant submarine resources, Yalong Bay is famed as “No.1 Bay under heaven”. The seawater is clean and blue here. Thanks to the high visibility of the seawater, it is definitely a good place to dive. Besides, swimmers can swim here all year round because the seawater temperature is very pleasant, from 22°C (71.6℉) to 25°C (77℉) all through the year.
