Photographs of Tiffany Blue in the golden sand dunes of Bintan Island Bintan Island may be unfamiliar to many people. This is a small island in Indonesia, which is a visa-free country. It is convenient to take a boat from Singapore. The island has not yet been fully developed, so there are few tourists and the sights are strange. For example, this place is called the golden sand dune. It has a lot of formations. It is said that in the Nanyang period, it is a gold mining area. Because the sand that has been dug is not treated well, the wind and the sun are raining. The drip, which has accumulated over time, has formed sand dunes of different sizes. Under the sun's rays, the sand dunes will refract different colors, either golden or white or bright red. The lake here is more beautiful, the blue lake is crystal clear, revealing the exquisiteness of Tiffany blue, which is in stark contrast with the golden sand dunes of the atmosphere, like the mosaic in this desert land. The emerald is general. In order to make the tourists take better pictures, some suggested wooden plank roads and photo points are built in the scenic spot. Although not so beautiful, they are somewhat interesting. Be sure to do a good job of sun protection here, because there is almost no place to cover the sun and rest, and you should pay attention to safety when climbing sand dunes.
