In Bai Tu Long Bay of viet nam, some 7 km east of Bai Tho (Poem) Mountain stands a stone islet, which resembles a huge magic wand in Andersen’s fairy tales. The islet is rocky mountain with 40 m high. From the northwest, It looks like imperial mandarin in blue uniform whose arms folded across his chest. Halong fisherman usually called Ong Islet instead of Dua Islet.
The Islet is a vivid evidence of the value of geological and geomorphological characteristics of the bay. The Islet is not only a fascinating sight on the Gulf but also a “lighthouse” for seagoing boats,Halong Cruises.
