Red Beach in Panjin, China
Panjin Red Beach in China is not covered in sand at all. The redness is caused by a type of sea weed, Sueda. It starts growing during April and May, then stays green during the summer, but starts turning vividly red in autumn.
The Red Beach is located in the biggest wetland and reed marsh in the world, and actually hosts the most completed ecosystem that can be found: the area has become home to more than 260 kinds of birds and 399 kinds of wild animals. You can find the endangered Crown Cranes and Black Beaked Gulls there, which is why the area is even called home of the cranes. (Source)
