Participate in the HaLong cruise, you will discover many interesting things of nature in this beautiful bay island.

Trinh Nữ Cave is situated in the island range of Bo Hon, in the system comprised of the Surprise Grotto, Dong Tien Lake, and Luon Grotto. The grotto is 15 km south of Bai Chay Beach. For some fishermen, the Virgin Grotto is home, while for young lovers it is a popular romantic rendezvous site.

According to legend, there once was a beautiful fisherman's daughter, whose family was so poor that they were in service of the rich administrator of the fishing zone, who forced the family to give him their daughter as a concubine. However, the fisherman’s daughter already had a lover and refused to marry the administrator. The administrator got angry and exiled her to a wild island where she suffered from hunger and exhaustion. One frightful night she turned to stone. On this same night, her lover, knowing of her danger, rowed his boat in search of her. However, a tempest destroyed his boat, and he floated to a nearby island. In a flash of lightening, he saw his lover in the distance, but his calls were driven away by the wind. In his final exhaustion, he also turned to stone (today’s Male Grotto).

When visiting the Virgin Grotto, you can still see the petrified girl with her long hair hanging down and eyes looking towards the mainland. Opposite the Virgin Grotto, the Male Grotto is still home to the lover whose his face is turned towards his mate. At times, his passionate calls and blows against the walls of the grotto can still be heard.
