Bai Chay beach is large, beautiful and closed to the coast of Halong Bay. The 100-meter-wide-sandy beach spans over 500 m.
Bai Chay is a low gently sloping range of hills that runs along the sea for more than 2 km. Blended in among the pine trees are large hotels and small villas with distinguished architectural styles. Early in the morning or in late afternoon, thousands of people liven up the atmosphere here. According to the locals, Bai Chay got its name long ago, based on another historical event. Bai Chay was once a forest. In 1287, the Mongols led by the great Truong Van Ho,(a Vietnamese name for this Mongolian general) attacked Vietnam and was driven back by general Tran Khanh Du. Many Mongolian ships were set afire and drifted to shore aided by high wind setting the forest on fire. Since then this stretch of beach became known as Bai Chay or scorched beach.
The asphalt road winds its way through the white sandy beach and luxuriant casuarinas. The Hoang Gia Tourism Company has invested in diverse services for tourists. The Bai Chay tourist site is fast changing into one of the most captivating of this kind in Ha Long City. It comprises restaurants, water puppet and traditional music theaters, Hoang Gia Park, water-skiing, and sea motorcycling. The Hoàng Gia Park lines along the Ha Long road leading from the Bai Chay Tourist Wharf to the gate of the Ha Long Night Market.
There are many legends associated with the name Bai Chay. According to one legend, when the fleet carrying food for the Yuan-Mongolian invaders led by Truong Van Ho came there, the Vietnamese troops and locals under the leadership of Tran Khanh Du set fire to it. The whole fleet was engulfed in fire. Meanwhile, the northeast wind blew hard and further added fuel to it. Fire was so fierce it burned down the forest in the western side of Cua Luc. Hence the name Bai Chay.
Another legend has it that the western side of Cua Luc used to be a wharf for seagoing boats. Acorn-barnacles firmly attached to these boats’ sides and underneath, and might wreck the boats. The local population had to use casuarinas leaves to burn acorn-barnacles. From Hon Gai and other neighboring places, people always see a blaze from there, so they called it Bai Chay.
