Viewed from above, Halong Bay Vietnam resembles a geographic work of art. While exploring the bay, you feel lost in a legendary world of stone islands. There is Man’s Head Island, which resembles a man standing and looking towards the mainland. Dragon Island looks like a dragon hovering above the turquoise water. La Vong Island resembles an old man fishing. There are also the islands of the Sail, the Pair of Roosters, and the Incense Burner, which all astonishingly resemble their namesakes. The forms of the islands change depending o¬n the angle of the light and from where the islands are viewed. At the core of the islands, there are wonderful caves and grottoes, such as Thien Cung (Heavenly Residence Grotto), Dau Go (Driftwood Grotto), Sung Sot (Surprise Grotto), and Tam Cung (Three Palace Grotto).
