The Red Beach is located in the Liaohe River Delta, about 30 kilometer southwest of Panjin City in China. The beach gets its name from its appearance, which is caused by a type of sea weed that flourishes in the saline-alkali soil. The weed that start growing during April or May remains green during the summer.
It is based in the biggest wetland and reed marsh in the world. The landscape is composed of shallow seas and tide-lands.
The Sueda species is one of the few species of grass that can live in highly alkaline soil. Its growth cycle starts in April when it is coloured light red, while the colour of the mature species is deep red.
