Asian Dragon Bay (Yalong wan) is arguably Hainans best beach and definitely the most pristine. 7 km of white sand stretches along beautifully clean blue water here, backed by palm trees and lush green hills.
 

The beach sits roughly on the same latitude as Hawaii and enjoys similar temperatures and weather conditions. The water here is wonderfully clear, reflecting the blue sky and white sand beneath the depths. Snorkeling and scuba diving are popular pursuits here given the clear water, bright-coloured coral reefs and tropical fish that abound and this is arguably the nicest place to swim on the entire island.This is a new resort and development is underway in a very tasteful manner. This is a protected marine reserve and commercial fishing is forbidden here, keeping the water very clean and lovely for swimming.
 

Facilities are also good here. This great beach is adjacent to shops, restaurants and a museum with a pretty collection of sea shells. There is also a charming outdoor butterfly garden here with a mountain hiking trail and some great walks. Hotsprings, numerous golf courses and submarine cruises are also offered.A nice trip from the bay is to Wild Boar Island. Take a boat from the bay to the island for some great snorkeling and swimming. Prices for this vary, so ask around at your hotel or in the restaurants on the bay.
